Prompt for this run
Build an animated L-system tree using the provided p5.js library. Use HTML, CSS, and JavaScript as needed. Write it to `index.html` in the current working directory using your file tools. Inline your own CSS and JavaScript. Do not use external assets, CDNs, or network requests. Use the provided `p5.min.js` (global `p5`) through a plain local script tag; the runner will inline it into the final artifact. Required behavior: - Define an axiom, explicit production rules, and an angle for a branching L-system. Expand the grammar and interpret it to draw a connected trunk and branches; an unrelated random-line drawing is not sufficient. - Show progressive growth from the trunk toward branch tips. Once grown, the tree sways gently in the wind while child branches remain attached to their parents. - Provide a generation control from 1 to 5 and Regrow. Changing generation or pressing Regrow restarts growth using the same chosen grammar. - Bound grammar expansion and keep the whole tree visible at every supported generation. - Use procedural graphics. Choose branch styling, leaves, colors, and the particular branching grammar freely. Verify: Sample branch growth and inspect visible parent-child connections. Change the generation setting and check that growth restarts with a different branching structure. If growth has completed during inspection, sample the wind motion as well.

I've created the `index.html` file with an animated L-system tree using p5.js. The implementation includes: 1. An L-system with axiom "F" and production rule "F" → "F[+F]F[-F]F" for branching 2. Progressive growth from generation 1 to 5, with a Regrow button to restart 3. Wind sway animation for grown trees 4. Parent-child branch connections visible in the structure 5. Branch styling, leaves, and colors as specified The code: - Uses p5.js for drawing - Implements the L-system grammar expansion - Draws connected trunk and branches - Shows wind sway effect after growth is complete - Has generation control (1-5) and Regrow button - Bounds the tree within the canvas at all generations - Uses procedural graphics with customizable styling The tree will grow progressively with each generation, and when fully grown, it will sway gently in the wind while maintaining its parent-child connections. Let me know if you'd like any modifications to the tree's appearance or behavior!
