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 current implementation has a few issues: 1. The tree is not properly expanding or showing progressive growth. 2. The wind effect is not applied correctly to the branches. 3. The tree structure is not visible as expected, and branches are not connected properly. I will fix these issues by: - Correcting the L-system grammar expansion and drawing logic. - Ensuring branches are connected to their parents. - Adding a proper wind effect to sway the tree. - Ensuring the tree grows progressively with each generation. Let's update the code.

The tree is still not displaying correctly, and the branches are not growing as expected. Let's refine the implementation to ensure the L-system grammar is correctly applied, the tree grows progressively, and the wind effect is applied properly. Here’s what I will fix: 1. **Correctly apply the L-system grammar** to ensure branches grow and connect properly. 2. **Adjust the `drawTree` function** to handle the stack correctly and ensure branches are drawn in the right order. 3. **Ensure the wind effect** is applied to the entire tree structure. 4. **Add a scaling factor** to reduce branch length with each generation to keep the tree visible. Let's update the code again.

The tree is now visible and correctly structured for generation 1, but it's not scaling or growing properly for higher generations. Let's fix the scaling and ensure the tree grows progressively with each generation. I'll adjust the `drawTree` function and ensure the length scaling is applied correctly. Here's the final fix:

The tree is still not scaling correctly for higher generations. Let's ensure the tree grows progressively and correctly by adjusting the scaling logic and ensuring the `drawTree` function uses the correct length for each generation. I'll make the final adjustments.

The tree is still not scaling correctly for higher generations. Let's simplify the approach and ensure the tree grows progressively by adjusting the length scaling and the grammar rules. I'll make a final adjustment to ensure the tree grows and scales properly.

It seems the tree is still not scaling correctly for higher generations. Let's simplify the approach by directly adjusting the length for each generation and ensuring the tree grows progressively. I'll make a final, more direct adjustment to the code.

The tree is still not growing correctly for higher generations. Let's take a different approach by ensuring the tree grows progressively and correctly by adjusting the grammar and scaling logic. I'll make a final attempt to fix this by implementing a more direct scaling method and ensuring the tree grows properly.

The tree is no longer visible, likely due to the scaling logic. Let's simplify the approach and ensure the tree is visible and grows correctly for each generation. I'll make a final adjustment to ensure the tree is visible and scales properly.
