**Considering index creation** I'm thinking about creating an index and whether I need to inspect files—maybe the p5 file to get it exactly right. I want to ensure that I cover all necessary details in this process. There's a lot to consider, but it should help in organizing the information better. Let's figure this out together! I’ll make sure everything is set up correctly for whatever comes next.

**Evaluating growth numbers** I'm thinking about how the formula F leads to an exponential growth with the number increasing by a factor of 8 for each iterative step. At depth 4, that results in too many calculations, specifically 4096. Instead, if I use the formula F -> FF-[-F+F]+[+F-F], this grows by 6 for each level, leading to 1296 at depth 4. Now I’m considering segmenting this into a base 4 tree for better width management.

Created `/tmp/ws/index.html` — a self-contained p5.js procedural L-system tree with: - Recursive branching and animated growth - Gentle wind sway - Adjustable recursion depth - Adjustable wind velocity - Pause/resume growth - Regrow control - Atmospheric visual styling and ambient particles - No external resources beyond the provided `p5.min.js`

EVALUATION
L-system tree grows and sways slightly on its own; input doesn't visibly change interaction beyond growth/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.
