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 L-system rules for branching 2. Recursively generates the tree 3. Has a gentle wind swaying animation 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 20:14 . drwxrwsrwx. 3 root node 16 Aug 1 20:14 .. -rw-r--r--. 1 node node 1034532 Aug 1 20:14 p5.min.js

Good, the p5.min.js file is present. Now I'll create an index.html file with: 1. An L-system fractal tree using p5.js 2. Recursive branching 3. Wind animation that makes the tree sway An L-system works by: - Starting with an axiom (initial string) - Applying production rules iteratively - Interpreting the string as drawing instructions (F = draw forward, + = turn right, - = turn left, [ = save position, ] = restore position) I'll create a classic tree L-system and add wind animation.

I've created the index.html file with an L-system fractal tree that: 1. Uses L-system rules (axiom: X, rules for X and F) 2. Recursively branches using the bracket operators [ and ] 3. Sways gently in the wind with oscillating wind strength 4. Has a dark atmospheric background with stars 5. Draws the tree with branch color gradients from brown/tan at the trunk to green at the tips Let me verify the file was created correctly.

The file has been created successfully. Let me give a quick summary to the user.
Created `/tmp/ws/index.html` with a procedural L-system fractal tree featuring: - **L-System Engine**: Uses axiom `X` with rules `X → F+[[X]-X]-F[-FX]+X` and `F → FF`, running 5 iterations - **Recursive Branching**: Uses `[` and `]` to save/restore state for branching - **Wind Animation**: The tree sways gently using layered sine waves that affect both branch angle and position - **Visual Polish**: - Dark gradient background with subtle stars - Branch color gradient from warm brown/tan (trunk) to green (leaves) - Varying branch thickness - Wind direction indicator The tree grows from the bottom-center of the canvas and the wind creates a natural, organic swaying motion.

EVALUATION
L-system fractal tree grows and sways gently in wind, but small, dark, and no branch leaves/thickness.

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.
