Using the pre-provided p5.min.js (global p5), grow a procedural L-system fractal tree that branches recursively and sways gently in the wind.

The user wants me to create a procedural L-system fractal tree using p5.js that: 1. Uses the pre-provided p5.min.js file 2. Branches recursively (L-system fractal) 3. Sways gently in the wind Let me first check what's in the current directory to see the p5.min.js file.
{"command":"ls -la /tmp/ws"}total 1012 drwxr-sr-x. 2 node node 23 Aug 1 20:13 . drwxrwsrwx. 3 root node 16 Aug 1 20:13 .. -rw-r--r--. 1 node node 1034532 Aug 1 20:13 p5.min.js

Good, the p5.min.js file is present. Now I'll create an index.html file with: 1. A fractal tree using L-system approach 2. Recursive branching 3. Wind animation that makes the tree sway gently Let me create a nice L-system fractal tree with: - L-system rules for branching - Recursive drawing - Wind effect that varies over time using sine waves - Beautiful styling I'll use a classic L-system approach: - Axiom: "X" - Rules: F -> FF, X -> F[+X][-X]FX (or variations) - Or a simpler approach with recursive branching that mimics L-system behavior Let me create an engaging visual with the tree swaying in the wind.

I've created the index.html file with: 1. A recursive L-system fractal tree using p5.js 2. Wind animation that makes the tree sway gently 3. Beautiful visual styling with gradient background 4. Color gradients from brown (trunk) to green (branches/tips) 5. Leaf clusters at branch tips 6. Multiple wind gusts for more natural movement Let me verify the file is there and looks correct.

The file is created. Let me verify the structure is correct by checking a portion of it.

The file looks good. It has: 1. p5.min.js loaded properly with `<script src="p5.min.js"></script>` 2. The L-system fractal tree code 3. Wind animation with multiple gusts 4. Recursive branching 5. No external dependencies The task is complete. The index.html file is ready with a procedural L-system fractal tree that: - Uses L-system rules for branching - Recursively branches (simulates L-system behavior) - Sways gently in the wind using sine wave animations with multiple wind gusts
Done! I've created `index.html` with a procedural L-system fractal tree featuring: **L-System Implementation:** - L-system string generator with rules (`X → F[+X][-X]FX`, `F → FF`) - Recursive branching that mimics L-system behavior with main branches and side branches - Additional random extra branches for a more organic look **Wind Animation:** - Multiple wind gusts with varying offsets, strengths, and speeds - Wind effect increases toward branch tips (more sway at the top) - Sine-wave based oscillation for smooth, natural movement - Wind indicator displayed in corner **Visual Features:** - Gradient background (dark night sky) - Color gradient from brown trunk → green branches → leaf clusters - Leaf clusters at branch tips - Ground grass/foliage at the base - Responsive canvas that fills the window The tree recursively branches 12 levels deep, with each branch having a 67% length decay and 25° branching angles, all animated with wind sway.

MEASUREMENTS
Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
