Animated loader · deepseek-v4-flash

Let me build a looping loading animation with GSAP. I need to use the gsap.min.js file that's already present in the current directory. Let me first check if it exists.

The gsap.min.js file exists. Now let me build the index.html file with all the required functionality. Let me plan:

1. Dark background
2. A group of rounded geometric shapes (e.g., a diamond, a star-like shape, circles) that smoothly change scale, position, and corner radius
3. A row of five dots with staggered motion or opacity
4. GSAP timeline with smooth easing, 3-6 seconds, repeats without abrupt jump
5. Pause/Resume and Restart controls
6. Center the composition
7. No external assets

Let me design:
- Shapes: I'll use inline SVG with several geometric shapes (a hexagon, a rounded square, a circle, a triangle) that animate
- Dots: 5 dots in a row with staggered animation
- Timeline: ~4 seconds duration with repeat: -1

Let me think about the shapes more carefully. I'll create them as SVG elements or HTML divs. SVG might be cleaner for geometric shapes.

Let me go with HTML/CSS for the dots and SVG for the shapes, all inside a centered container.

I'll use:
- A large shape that morphs between a circle, rounded square, and diamond
- Supporting smaller shapes orbiting or scaling
- 5 dots that pulse with staggered delays

Let me write this out.

Let me test it in the browser to see the initial output.

Let me take a screenshot to see what it looks like and check console for errors.

Can't see images, but I can interact with the DOM and check console. Let me inspect the DOM and the current state of the animation.

I need to check if the GSAP library is loading correctly. Let me try inspecting the document more deeply and check for any errors in the console.

Let me check the console messages more carefully. The browser tool only shows one console warning about sandboxing. Let me try running a script in the page to check if GSAP is loaded. Actually, let me re-read the file I wrote and check for any issues.

One issue I see: I'm using `attr: { rx: 30, ry: 30 }` on the rect element, but GSAP's attr plugin works for SVG. However, I'm also using `cx` and `cy` attributes on the circle with `attr`, but `cx` and `cy` on circle are also SVG attributes. That should be fine.

Another issue: the `s2` triangle uses `x` and `y` properties, but `x` and `y` aren't standard transform properties. GSAP might handle them but they could be undefined. Let me use `translateX` and `translateY` or use the transform string approach.

Wait, actually for SVG elements, GSAP can handle x and y as transform properties (it maps them to SVG transforms). But that might not work correctly in all cases. Let me also check if the shape-2 being a polygon has issues with rotation center.

Let me also double-check: the s1 element is a `rect` with x=40, y=40. When I do `gsap.to(s1, { x: 30, y: 30 })`, GSAP will apply a CSS transform translate(30px, 30px) relative to its original position. That's probably okay but might not be what I intended since it already has x=40,y=40 in SVG. Actually, for SVG elements, GSAP treats x/y as SVG x/y attributes, not CSS transform. This could cause issues because the rect already has x=40, y=40 and setting x=30,y=30 via GSAP would change the SVG attributes. That should work.

But there's a subtle issue: when GSAP yoyo repeats, it should go back to original values. Let me think about this more carefully.

Actually, let me rethink the approach. Using GSAP with SVG attributes can be tricky. Let me write a cleaner version that uses CSS transforms (scale, rotate, translate) on wrapper groups, or uses SVG more carefully.

Let me rewrite with a simpler, more reliable approach:
- Use SVG groups (`<g>`) with transform attributes for positioning shapes
- Use GSAP to animate CSS properties or use the `transform` approach via GSAP

Actually, let me reconsider. The main issues I see:
1. GSAP might set `rx`/`ry` on a rect element via `attr` plugin, but the rect might not have `rx`/`ry` set initially - this should work.
2. For the circle, setting `attr: { cx: 190, cy: 30 }` should work.
3. For shapes, `x` and `y` in GSAP for SVG elements are treated as SVG attributes, which might conflict with CSS transforms.

Actually, let me just check if there were any errors. Let me see what's happening by refreshing and checking console more carefully.

Let me try node or python.

Good, the file is structured properly. Let me try to see if there are any errors in the browser by running a JavaScript evaluation there. Let me use the browser tool's key events or typing to check the console.

Actually, I can't really see runtime errors from the browser tool that way. Let me instead try a different approach - let me use `inspect` to look at the page's current state.

Let me also think about whether the animation actually works. One potential issue: SVG `x` and `y` attributes are read-only for certain elements? No, GSAP's attr plugin should handle them.

Actually, wait - there's a potential issue with how I'm using `x` and `y` on the rect (s1). In SVG, `x` and `y` are attributes of the rect element that control its position. GSAP's default behavior for SVG elements when you animate `x` and `y` is to treat them as CSS transform properties (translateX and translateY). But the `attr` plugin handles SVG attributes. However, in my code I'm not using the attr plugin for x and y on s1 - I'm using plain `x: 30, y: 30` which GSAP would try to animate as CSS transforms (translateX, translateY).

Wait, actually, for SVG elements, GSAP by default treats x and y as SVG attributes? No, that's only with the attr plugin. Without attr, GSAP treats x and y as CSS transform properties (translateX, translateY) for all elements. But for SVG elements, CSS transforms work fine in modern browsers.

Hmm, let me reconsider. When I do:
```js
tl.to(s1, { x: 30, y: 30, ... })
```
GSAP would try to animate `s1.x` and `s1.y` properties, which on a DOM element don't exist directly, so it falls back to CSS transforms. For SVG elements in modern browsers, CSS transforms work.

But then the initial position of the rect is x=40, y=40 in SVG coordinates, and we're applying a CSS transform translate(30px, 30px) which offsets it by 30px from its original position. That's different from setting the SVG x/y attributes.

Actually, I think this is fine for the animation effect, but the `yoyo: true, repeat: 1` should bring it back and forth properly.

Let me check the browser again to see if there are visible issues.

The console shows no JS errors, which is good. Let me try to interact with the page - click the Pause button, check the animation state.

But wait - the browser inspector shows "Pause\nRestart" which is just the button text. I can't see the SVG shapes or dots rendered. Let me check if GSAP is actually running by trying to evaluate JS in the page.

Let me try to click the Pause button and see what happens.

The coordinates might be wrong. Let me check the page layout. The buttons are at the bottom. Let me try to figure out the positions.

Actually, I think the issue might be the viewport size. Let me click somewhere near where the buttons would be. With flexbox centering and the layout, the buttons should be somewhere in the lower middle area.

Let me also try to see if I can evaluate JS to check the state. Actually, I'll use the `type` action to inject some JS evaluation.

Hmm, but actually, the main thing I need to verify is:
1. The animation plays
2. The shapes change
3. Dots stagger
4. Pause/Resume works
5. Restart works

Let me try clicking around and see if the Pause button click changes its text.

Still showing "Pause\nRestart" - the button text hasn't changed, which means I didn't click the Pause button (it should change to "Resume" on click). Let me try different positions. The buttons are in a flex container at the bottom, so they should be somewhere around the lower portion of the viewport.

Let me think about the layout:
- Container is flex column, centered
- shapes-wrap: 220px + gap 48px
- dots: some height
- gap 48px
- controls: buttons ~40px height
- Total: roughly 220 + 48 + ~50 + 48 + 40 = ~406px of content, centered vertically

In a 800px viewport height, centered content would start at about (800-406)/2 = ~197px from top, and end at ~603px.

The buttons would be at the bottom of the centered content, so around y=570-620.

Let me try x=500, y=580 for the Pause button (which is the left button).

Wait, actually the container has gap: 48px between each child. The shapes-wrap is first, then dots, then controls with extra margin-top: 8px.

Content height: 220 + 48 + 16 + 48 + 8 + 40 = ~380px
Centered start: (800-380)/2 = 210px
Buttons y: 210 + 220 + 48 + 16 + 48 + 8 = ~550px

Let me try y=550.

Still "Pause\nRestart" - I'm not hitting the button. Let me try a wider range. Maybe the flex layout with centering puts the content differently.

Actually, let me think about this differently. The body is `display: flex; align-items: center; justify-content: center; min-height: 100vh`. With the viewport at 1200x800.

Actually, I should try scrolling first or try clicking in a grid pattern. Let me try x=500 and a few y values.

Or better, let me try to click the first button. Since the buttons are in a flex row centered, and the Pause button is the first one, it should be at approximately x=500 (center - offset for button widths).

Button width: ~100px each (padding: 8px 22px, text ~50px)
Gap: 12px
Total: 100 + 12 + 100 = 212px, centered around 600px
Pause button: from ~494 to ~594
Restart: from ~606 to ~706

So x=545 is roughly the center of Pause button.

Let me try that with different y values.

Still not hitting the button. Let me try more systematically. Let me use keyboard/mouse to get more info. Actually, let me try to scroll and see what happens. But first, let me try some other y values.

Let me try typing in the console to check the state.

Let me try more systematically.

Let me try a much higher y value, maybe the content is pushed down differently than I calculated.

Let me try even lower.

Still not clicking the button. Hmm, maybe the viewport isn't 800px tall. Let me check what `min-height: 100vh` resolves to. Actually, the browser says it uses a 1200x800 viewport. But maybe the content is scrollable.

Let me try scrolling down to see if the content is below the fold.

OK, so scrolling works. Let me try clicking at a higher position after scrolling, or maybe the buttons are at a different y now. Let me scroll back up first.

Actually, let me reconsider. Maybe the issue is that `min-height: 100vh` in the iframe context doesn't work as expected. Let me check by scrolling to various positions and trying to click.

Let me first scroll to top, then try clicking at different positions systematically.

Let me try a completely different approach. Let me try to check if there are JS errors by looking at the page structure more carefully. Let me also try to evaluate some JavaScript in the page to see if GSAP is loaded.

Actually, I realize I haven't seen any console errors from JS, which is good. Let me try typing or clicking more carefully. Maybe I need to find the exact coordinates of the buttons.

Let me try a drag action or something to see coordinates.

Actually, let me try evaluating JS by clicking somewhere and checking. Or let me just try different coordinates systematically.

The page doesn't change when I click anywhere, which could mean:
1. The page is not interactive (JS not working)
2. I'm not clicking where the buttons are
3. The viewport coordinates don't match the actual rendering

Let me try to reload and then inspect more carefully. Let me also try using the `type` action to type into an input field... but there are no input fields.

Let me try another approach - use `inspect` to get the full DOM tree.

The inspect output seems very minimal. It just shows the text content "Pause\nRestart" which is what's between the two buttons. It seems like the DOM inspection might be limited.

Let me check if there are any runtime errors. Let me try reloading and then checking.

Still only one console message - the warning about sandboxing. No JS errors. GSAP should be loading fine.

Let me try to find the buttons by clicking in a more systematic way. I'll try a grid search pattern.

Actually, you know what, let me check if the page even has the right elements. Let me see the full HTML by evaluating some JS. But I can't evaluate JS directly through the browser tool.

Wait, I can use the `type` action with `text` to type into an element. But there's no input field.

Let me try clicking at a wider range of positions. Let me try x=300 (far left) or x=900 (far right).

Let me try to click at the very bottom of the viewport.

Still nothing changes. The DOM output shows "Pause\nRestart" but maybe it's not updating properly. Let me look more closely at the actual page structure. 

Wait - I just realized something. The DOM output says "Pause\nRestart" - this is just the text content of the buttons. The buttons are:

```html
<button id="btn-pause">Pause</button>
<button id="btn-restart">Restart</button>
```

So the DOM text would be "Pause\nRestart" as those are the visible texts stacked vertically... wait no, they're in a flex row with `gap: 12px`, so they'd be side by side. The "Pause\nRestart" with a newline between them is just how the browser tool reports the combined text.

Let me actually try to type into the page to execute some JS. Wait, I can't do that without an input.

Let me try a different approach. Let me take a screenshot to see what's happening.

Actually, the browser tool says "images": "model does not support images" - so screenshots don't work. But I can still interact.

Hmm, let me reconsider. Maybe the fact that I'm not seeing any change in the DOM output means the buttons aren't being clicked. Let me try to check if the page has correctly loaded GSAP by evaluating something, but I can't do that directly.

Actually, maybe I should try the `type` action to inject text? No, that requires a focused element.

Let me try clicking on the buttons more precisely. Maybe the issue is that the button text "Pause" changes to "Resume" on click, but I need to verify this.

Let me try to find the button coordinates more carefully. In the 1200x800 viewport:
- The container has flex centering
- shapes-wrap: 220x220
- dots: ~16px + gap spacing
- controls: two buttons side by side

Total content height: 220 + 48 + 16 + 48 + 8 + ~40 = ~380px
Centered top: (800-380)/2 ≈ 210px

So buttons are at roughly y = 210 + 220 + 48 + 16 + 48 + 8 = ~550

BUT - this assumes the body fills the full viewport with `min-height: 100vh` and flex centering. In an iframe, 100vh might be different.

Let me try more y values systematically from 400 to 700.

OK I'm going to try a completely different approach. Let me check if perhaps the page didn't render at all because of some issue, or if the DOM output is just truncated. Let me try clicking at many positions across the viewport quickly.

Actually, wait - I know what might be happening. Maybe the browser isn't loading the page properly because there's a syntax error in the JS that prevents gsap from loading, but the console doesn't show it? No, JS errors would show in console.

Let me try to check by running a very simple test. Let me rewrite the file with simpler content first to verify the browser tool works, then rebuild.

Actually, let me first verify that clicking works at all by creating a simple test.

I can't change the URL the browser loads - it loads index.html. Let me put this test into index.html temporarily.

Let me check the browser to see the console output now.

Now I can see the console output! 

- The first script runs before GSAP is loaded, so `gsap` is undefined.
- The second script runs after GSAP is loaded, and `gsap` is available with `timeline` function.

So GSAP IS loading correctly. The page renders with the buttons and the shapes/dots should be there.

Now let me try clicking the "Click to test" button. Its text should change to "CLICKED OK". Let me find its coordinates.

The buttons are in a row at the bottom. The "Click to test" button is first, then "Pause", then "Restart". With 3 buttons, each about 120px wide (padding 8px 22px = 30px padding + text ~60px), and gap 12px.

Total width: ~120 + 12 + 100 + 12 + 100 = ~344px
Centered in 1200px viewport: from (1200-344)/2 = 428px to 428+344=772px

"Click to test" button: from 428 to ~548
"Pause" button: from 560 to ~660
"Restart" button: from 672 to ~772

Y-coordinate: same as before, around 550-570 depending on centering.

Let me try clicking at x=488, y=550 (center of "Click to test" button) and x=610, y=550 (center of "Pause" button).

Still "Click to test" - didn't change. Let me try different y values.

Let me try a much higher y - maybe the content is at the top of the viewport.

Let me try a truly exhaustive search. Going through different y coordinates systematically.

Actually wait - maybe the container isn't being displayed because there's a JS error in my test page that happens before the button clicks? Or maybe the click event isn't being propagated correctly?

Actually, let me just check: maybe the onclick attribute isn't working because the script runs after? No, the inline onclick should work regardless of script order.

Let me try to scroll down first and then click.

Let me try clicking at various positions after scrolling.

Let me try a different approach. Let me scroll back to top and try clicking near the very bottom.

Let me try clicking at various y positions at a fixed x.

Let me try clicking at x=488, y=10.

Let me try a different x.

OK, the clicking doesn't seem to be changing the button text. This might be because the click events aren't being registered, or the DOM reporting is cached.

Let me reload the page and then try clicking immediately.

Let me try using the `key` action to see if keyboard events work. Let me try typing something.

Let me try clicking exactly at the center of the viewport (600, 400) and then at many other positions.

Actually, maybe the problem is that the `onclick` attribute isn't working in the sandbox. Let me try a different approach - use addEventListener instead, or maybe the click coordinates just don't match.

Actually, wait - maybe the viewport size is different. Let me check by trying to click at the edges.

I'm going to accept that the click interactions might be limited in this test environment and focus on ensuring the animation code is correct. I know GSAP loads (confirmed from console logs). Let me now rebuild the full animation with the working GSAP library.

Let me write the proper full version now. Based on what I know:
1. GSAP loads fine from the local file
2. The DOM renders correctly
3. Click interactions might be unreliable in this test environment

Let me write the full animation. I'll be careful with the code.

Now let me reload the browser and check for any console errors.

No JavaScript errors! The animation is running. The console shows no errors and no unexpected warnings (only the sandbox warning).

Now let me try to interact with the buttons. Let me try clicking at different positions to find the buttons. Let me calculate more carefully where the buttons would be.

Actually, I know that the viewport is 1200x800. The content height approximately:
- shapes-wrap: 220px
- gap: 40px
- dots row: ~14px
- gap: 40px
- controls: ~40px
- margin-top: 8px
Total: 220 + 40 + 14 + 40 + 40 + 8 = ~362px

Centered in 800px height: top = (800-362)/2 = 219px

The controls row would be at y ≈ 219 + 220 + 40 + 14 + 40 = 533px to 573px.

The controls buttons are centered horizontally. Two buttons each ~90px wide (min-width: 80px + padding 22px*2 = 44px + text ~30px = ~84px, let's say ~90px each). Gap: 12px. Total: 192px. Centered in 1200: from (1200-192)/2 = 504px to 504+192 = 696px.

Left button (Pause): from 504 to 594, center at 549
Right button (Restart): from 606 to 696, center at 651

Y would be around 545-565.

Let me try clicking at (549, 553) - center of Pause button.

It worked! The button text changed from "Pause" to "Resume", confirming the pause functionality works. Let me now click "Resume" to resume the animation.

Resume works - button went back to "Pause". Let me now test Restart.

Restart works (button text unchanged, which is expected). Let me verify a few more things:

1. Let me pause, wait a moment, then resume to check that it continues from paused state (not jumping)
2. Let me test Pause → Restart → check initial state

Let me pause first, wait, then check.

Now it shows "Resume" - meaning it's paused. Let me wait a moment and then click Resume, and then immediately Pause again to see if it continued from where it was.

Actually, the best way to verify this is:
1. Pause → note state (Resume button shown)
2. Click Restart
3. Check if button goes to "Pause" (meaning Restart restarted and unpaused)

Let me try that:

Restart from paused state works correctly - button goes back to "Pause" (animation restarted and playing).

Now let me test the full flow:
1. Pause (done - shows Resume)
2. Resume (continue from paused state) - let me click Resume now
3. Then Restart

Hmm, the second click on the Pause button didn't toggle - it's still showing "Resume". Wait, it went from "Pause\nRestart" to "Resume\nRestart" - that means the Pause button was clicked, toggling to Resume mode. Let me click again to toggle back to resume mode.

Wait, no. Let me re-read:
- First: "Pause\nRestart" (animation playing)
- Click (549,553): "Resume\nRestart" (paused, button says Resume)
- Click (549,553) again: "Resume\nRestart" (still same - wait, it should have toggled back)

Hmm, actually I think the tool might not be registering the click correctly. Let me try again more carefully.

Wait, let me re-trace:
1. Initial: "Pause\nRestart" (playing)
2. Click Pause: "Resume\nRestart" (paused)
3. Click Restart: "Pause\nRestart" (restarted and playing)
4. Click Pause: "Resume\nRestart" (paused again)

OK so steps 1-4 are:
1. Playing → Pause shown
2. Click Pause → paused → Resume shown
3. Click Restart → restarts → Pause shown
4. Click Pause → paused → Resume shown

So step 4 was just a pause toggle. The animation is paused. Let me click Resume (same position) to resume it.

Resume works - button went back to "Pause". Now let me verify one more thing: let me pause, then restart, and check the initial state.

Actually, I've been able to verify the key behaviors:
1. ✅ Pause: button changes to "Resume"
2. ✅ Resume: button changes back to "Pause"
3. ✅ Restart: animation restarts, button shows "Pause"
4. ✅ No JS errors
5. ✅ GSAP loads correctly from local file
6. ✅ Animation runs (no JS errors means the timeline is executing)

The animation cycle is 4 seconds and repeats infinitely. The user requirements are:
- Dark background ✅
- Group of rounded geometric shapes that change scale, position, and corner radius ✅
- Row of five dots with staggered motion/opacity ✅
- GSAP timeline with smooth easing ✅
- 3-6 seconds duration (4s) ✅
- Repeats without abrupt jump ✅ (yoyo with proper easing)
- Pause/Resume and Restart controls ✅
- Centered composition ✅
- SVG shapes (no external assets) ✅
- Local gsap.min.js ✅

Let me now verify the timing to make sure my H=2 (half-cycle of 2s) with yoyo:true, repeat:1 gives a total cycle of 4s. Let me think about this...

Each tween has yoyo:true and repeat:1, which means it goes forward (2s) and back (2s) = 4s total. Then repeat: -1 on the timeline makes it loop. Since all tweens start at offset 0, they all complete their yoyo cycle in 4s, and the timeline repeats seamlessly. 

However, I realize there might be a subtle issue: some tweens have a delay (like offset 0.3, 0.5, 0.6). These will complete later than the main 4s cycle. But since they also have yoyo:true, repeat:1, they'll complete their full forward+backward cycle in 4s regardless of when they start. So after the first 4s cycle, timing should settle.

Actually, let me reconsider: if a tween starts at 0.3 and has duration H=2 with yoyo:true repeat:1, its total animation takes 4s, ending at 4.3s. The timeline repeats at 4s (totalDuration). So there would be a slight mismatch.

To fix this, I should make sure all animations complete within the same total duration. Let me adjust the approach.

Actually, the better way is to set the timeline's total duration explicitly OR make sure all animations fit within the same time window.

Let me recalculate. The simplest approach:
- Set timeline duration to exactly 4 seconds
- All animations complete within those 4 seconds
- Use yoyo:true, repeat:1 for each, but offset them so they all fit in 4s

For a yoyo with duration H and repeat:1, total time is 2*H. If some start at offset D, they end at D + 2*H. For everything to fit in 4s: D + 2*H <= 4.

Currently:
- Dots: H=0.5, D=0, ends at 1.0 ✅
- Dots color: H=2, D=0, ends at 4.0 ✅
- Shape A attr: H=2, D=0, ends at 4.0 ✅
- Shape A scale: H=2, D=0, ends at 4.0 ✅
- Shape A rotation: H=4, D=0 -- wait H*2 = 4 for rotation! That means total with yoyo:true, repeat:1 is 8s. That's too long!

Let me fix this. I need to make sure all animations fit within 4s total.

Let me rethink the timing:
- Total cycle: 4s
- Shape A rotation: 180° rotation in 2s one way, 2s back = 4s total. So duration should be 2, not 4.
Current: `duration: H * 2` where H=2, so duration=4. With yoyo/repeat, total = 8s. Wrong.

Let me fix all the durations to fit within 4s.

Actually, a cleaner approach: make the timeline 4s total, and don't use repeat on individual tweens - instead just let them play once with yoyo (which goes forward and back). Then the timeline repeat handles the looping.

If I use `yoyo: true, repeat: 1` on each tween, that's fine as long as:
- duration = H, repeat: 1, yoyo: true → total time = H * 2
- For offsets D, they need D + H*2 <= total timeline duration

Let me set timeline duration explicitly: `tl.duration(4)` and make everything fit.

Or simpler: don't use yoyo/repeat on individual tweens. Just animate forward once (duration = 2s) and use timeline's yoyo with repeat: -1 on the entire timeline.

Wait, but the requirements say different elements animate at different times. Let me think about this differently.

Best approach: Use a single 4s timeline with no per-tween repeats. The timeline itself has repeat: -1. For effects that need to go back and forth, use yoyo on the timeline level OR use separate forward/backward tweens.

Actually, GSAP timeline with repeat: -1 will replay the entire timeline. If I want smooth looping, the starting state should equal the ending state. With yoyo on the timeline, the entire thing reverses, which creates a natural loop.

Let me try this cleaner approach:

```js
const tl = gsap.timeline({ repeat: -1, yoyo: true });
```

Then each tween just animates one way (no individual yoyo/repeat). The timeline's yoyo reverses all of them. Total forward time should be about 2-3 seconds.

This is much cleaner! Let me rewrite.

Let me reload and test again.

No JS errors. Let me test the controls again to verify they still work.

Pause works. Let me test Resume and Restart.

Resume works. Let me test Restart.

Restart works. Let me verify the Pause → Restart flow:

Good, animation paused. Now let me click Restart to restart from paused state.

All control flows verified:
1. ✅ Pause → Resume → works smoothly
2. ✅ Restart from playing state works
3. ✅ Restart from paused state works (unpauses and goes to beginning)
4. ✅ No JS errors at all
5. ✅ GSAP loads from local file

The file is complete. Let me verify it one more time by reading the final file to make sure everything is in order.

The "Self-contained: false" is because of the `script src="gsap.min.js"` - the instructions say to load that from a plain local script tag since it's already present in the directory. That's correct per the requirements.

Also there might be false positives from checking for http/https - let me double check.

Actually wait, let me check what's making it say "false":

That's the SVG namespace URL `http://www.w3.org/2000/svg`, which is fine - it's an XML namespace, not a network request. The check is misleading. In a sandboxed environment, SVG namespace declarations don't trigger network requests and are purely declarative. So the file is truly self-contained.

Everything looks good. Let me report the results.
