**Developing the App Framework** I'm focusing on the single-page structure now. I'm prioritizing the internal CSS and JavaScript for the `index.html`. My main goal is to integrate GSAP (from the provided `gsap.min.js`), and I'm planning out the dark background and animated loading sequence with the morphing shapes.

**Considering Shape Transitions** I've confirmed the GSAP library is present, so I can start integrating it. I'm focusing on shape morphing and considering approaches beyond MorphSVG. Specifically, I'm looking at animating `border-radius`, animating `path` data with equivalent points, and simulating morphing using blob shapes. I'm leaning toward exploring those methods first. **Designing the Loader Structure** I'm now building the `index.html` structure. It'll have a container for the loader, with two or three background "morphing" blobs and a row of foreground dots. I'm thinking of a dark background like `#111`. I'll center the content and style the blobs with some transparency and glow. GSAP will be used to animate the blobs and dots. I'll experiment with `borderRadius` to achieve the "blobby" look. **Defining the Loader Styles** I've crafted the foundational CSS for the loader. The body is set to `#f0f0f0` with flexbox centering. Within, the container uses absolute positioning for blobs, `z-index` control, and blob positioning with size, background gradients, blur effects, and opacity. Specifically, I've styled two blobs, with varying sizes, gradients, and opacity levels. The styles set a foundation for the loader's visual elements. **Implementing Loader Content** I've recently added the HTML structure, including two background blobs and a row of dots, along with a "Loading" text element. CSS styling is included, setting a dark background and positioning elements. I'm focusing on defining flexbox for dot alignment, background and glow effects, using `z-index` to control stacking. The dots are white, with a 50% opacity and are styled with a glow, and their row uses a 15px gap. **Animating the GSAP Script** I've now integrated the GSAP script to animate the blobs and dots. I set up a timeline for the dots and animations for `blob-1` and `blob-2`, utilizing `borderRadius`, `rotation`, and `scale` properties, and defined their parameters. I'm repeating them indefinitely with `yoyo` and specified easing functions. I've also implemented a staggered animation for the dots, changing their `y` position, scale, and background color. **Orchestrating Shape Animations** I've refined the GSAP animations further. The dot animation is staggered and sequenced to fit a specific timeline, alongside morphing blobs. I've considered how best to integrate a smooth transition between the two, using power2.inOut ease. I'm focusing on text opacity, duration, repetition, and the yoyo effect. **Refining the Blob Look** I'm now focusing on refining the "morphing rounded shapes" with `border-radius`. I'm exploring CSS blob shapes for this, aiming to achieve a liquid and "morphy" appearance on a dark background with blur. I'm focusing on crafting a smooth, animated transformation of CSS blob shapes using a GSAP timeline. I've re-reviewed the requirements, including the use of CSS blobs and a single, self-contained `index.html` file, and confirmed that `gsap.min.js` is already present.

**Confirming Project Completion** I've finished building the app and verified all criteria. A swift code review confirms I've met the specifications, ending with `index.html` as the only required file. **Refining Visual Implementation** I'm now zeroing in on the finer points of the implementation, and I've verified the core aspects of the animation meet the requirements. I've also checked the local GSAP import strategy, ensuring it complies. I'm considering integrating the text updates within the GSAP timeline using `.call()` to achieve full orchestration; it's a small touch that would make the implementation more cohesive. I think my use of `borderRadius` to create morphing blobs meets the client's request.

**Fixing the timeline bug** I've got it! I realized I messed up the timeline's construction in the last edit. Specifically, I omitted some crucial `.add()` calls to the master timeline, which caused the animations to not trigger. Now, the `.add()` calls should be present, and the animations should play as intended in the current file.
