Sandbox Base

This branch is a fresh starting point for fast canvas/WebGL prototypes. It keeps the tooling (Vite + vanilla JS) but strips out previous experiments so every new idea starts from the same clean slate.

Dev workflow

1. Install deps once: npm install
2. Run locally: npm run dev
3. Build for static hosting: npm run build

Creating a new prototype branch

1. Make sure the base is up to date:

   git switch main
   git pull

2. Spin up a branch for your idea:

   git switch -c proto/<idea>

3. Edit files in src/ (or clone the template in src/prototypes). Keep commits local to that branch.
4. Push/publish when you want to share:

   git push -u origin proto/<idea>

5. When the experiment is done, tag it or delete the branch—no merges back to main required.

Runtime pieces

• src/core/host.js – wires canvases, the control panel, pointer events, and the RAF loop.
• src/core/canvas.js – DPI-aware helpers for 2D and WebGL contexts.
• src/core/controls.js – minimal UI renderer for sliders, colors, selects.
• src/prototypes/*.js – drop-in modules that expose { id, title, controls, create() }.

See docs/prototypes.md for a deeper breakdown of the contract between the host and each prototype.
