CANVAS_TEMPLATE_HINT = """
Starter template guidance for a plain canvas game:

index.html
- Create a centered app shell with:
  - a header area for title and score
  - a main game canvas
  - a mobile controls section with large directional/action buttons
  - a restart button

style.css
- Use a responsive layout that stacks nicely on mobile.
- Keep the canvas visible without horizontal scrolling.
- Add `touch-action: none;` for interactive game controls.
- Use clear visual contrast and large tap targets.

script.js
- Create explicit game state variables.
- Create a `resizeGame()` function if canvas sizing matters.
- Create a `startGame()` / `resetGame()` flow.
- Create a `gameLoop()` driven by `requestAnimationFrame` or a timed tick.
- Add keyboard listeners and touch/click listeners.
- Keep gameplay fully self-contained without external assets.

THREE_JS_TEMPLATE_HINT = """
Starter template guidance for a Three.js browser game:

index.html
- Include a UI overlay for score, status, and restart.
- Load Three.js with a browser-safe CDN module import in script.js.

style.css
- Full-viewport scene layout.
- Overlay HUD pinned above the renderer.
- Mobile-safe action buttons if touch input is needed.

script.js
- Set up:
  - scene
  - perspective camera
  - renderer sized to the viewport
  - ambient + directional light
  - resize handler
  - animation loop
- Keep geometry lightweight for mobile.
- Use simple primitives and colors instead of relying on asset pipelines.
- Implement gameplay logic on top of the render loop, not just a visual demo.
"""


PHASER_TEMPLATE_HINT = """
Starter template guidance for a Phaser game:

index.html
- Include a HUD area for score and status.
- Load Phaser from a browser-ready CDN.

style.css
- Center the game canvas and ensure it scales on mobile.
- Add large touch-friendly controls when needed.

script.js
- Use a Phaser config with `type`, `width`, `height`, `parent`, `backgroundColor`, and scaling rules.
- Create at least one scene with `preload`, `create`, and `update`.
- Use primitive graphics or generated shapes if no external assets are required.
- Add restart behavior and visible score/status updates outside or inside the Phaser scene.
