Done — `index.html` contains a self-contained p5.js L-system tree: - **L-system grammar**: axiom `F` with stochastic rules (`FF-[-F+F+F]+[+F-F-F]` variants) seeded deterministically, so each "Regrow Seed" gives a new unique tree. - **Turtle renderer**: `[`/`]` push/pop recursion for branches, trunk thickness tapering with depth, brown trunk fading to green leaf dots at the tips. - **Wind sway**: layered sines + p5 `noise()` gust, applied more strongly at the tips and on branch rotations. - **UI controls**: iterations (1–7), branch angle, wind strength, and a regrow button. Sky gradient background, all offline with the local `p5.min.js`.

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.
