The whole page was created with Claude Code. These were the most significant prompts that shaped this page:

1. Write a JavaScript parser for the fractint.l format in index.php and load the data via PHP.
2. Add a dropdown below the canvas filled with all the fractal names so I can select a fractal.
3. Render the currently selected fractal in the canvas by using l-system rules.
4. Add an iteration count control.
5. Allow iteration to be 0, so I can see the axiom.
6. Currently the letters F G are hardcoded. The rules can use any letter, like FlowSnake uses L R and F. You have to find the correct rule, based on the previous iteration. (Led to replacing string expansion with recursive turtle drawing.)
7. Yes, implement @ scale handling.
