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'll build an animated L-system tree using p5.js with the requested features.

I've created an animated L-system tree with the requested features. The implementation includes: 1. An L-system with axiom "F" and production rule "F" → "F[+F]F[-F]F" with a 25-degree angle 2. Progressive growth from trunk to branch tips 3. Gentle swaying motion in the wind after growth completes 4. Generation control (1-5) and Regrow button that restarts growth with the selected generation 5. Tree remains visible at all generations with appropriate scaling 6. Procedural graphics with branch styling, leaves, and colors The tree will grow progressively from the trunk outward, and once fully grown, it will sway gently in the wind. The generation control allows you to select different levels of branching complexity, and the Regrow button restarts the growth process. I'll now run the application to verify the behavior.

I can see that the tree is starting to grow, showing just a single trunk line in the center of the screen. Let me continue to observe the growth process and verify the required behaviors.

I can see that the tree is growing vertically, but it's not yet showing the branching structure I expected from the L-system. Let me check if there are issues with the L-system implementation and fix them to ensure proper branching occurs.

I need to fix the tree drawing logic to properly handle the L-system branching structure. The current implementation isn't correctly interpreting the L-system grammar to create branches. Let me update the code to properly handle the branching and ensure the tree grows with the correct structure.

10 minutes have elapsed. At most 5 minutes remain. Finalize the output as soon as possible: save index.html now, fix only essential issues, and finish.
I need to make final changes to ensure the tree grows with proper branching structure. Let me update the code to fix the L-system implementation and ensure the tree displays correctly with parent-child connections.

I need to make final changes to ensure the tree displays correctly. Let me rewrite the entire Tree class with a simpler approach that will work with the L-system grammar and create branches with parent-child connections.
