- src/shell.html: Custom HTML shell with crisp pixel CSS
(image-rendering: pixelated) and zoom prevention on canvas
- src/emscripten_pre.js: Patches browser quirks that cause crashes:
- Intercepts resize/scroll events to ensure e.detail is always 0
- Wraps window properties (innerWidth, outerWidth, etc.) to
always return integers, fixing browser zoom crashes
- CMakeLists.txt: Output as .html, include shell and pre-js files
The pre-JS fix addresses "attempt to write non-integer (undefined)
into integer heap" errors that occurred when users zoomed the browser
via Ctrl+scroll or browser menu.
