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.

The error in the console is due to a syntax error in the script. Let's fix the `drawTree` function and ensure the L-system tree is drawn correctly. I'll correct the logic and ensure the tree is rendered properly.

The tree is not rendering due to the incorrect placement of the `drawTree` function and the logic flow. Let's restructure the code to ensure the tree is drawn correctly. I'll fix the function calls and ensure the L-system string is expanded and drawn properly.
