/* Bye Bye, Hell demo page. Scoped to body.bbh so nothing leaks into the rest of the site.
   Everything here is lifted from the game itself:
   - the font is the game's own 5x7 bitmap font, rebuilt from its atlas (1 art pixel = 1/8 em, so keep sizes on multiples of 8px);
   - sprites are cut from the same atlas and drawn at whole-number scales with pixelated scaling;
   - colours come from Hud.ts (title, prompts, buttons), clipped from the game's overbright values. */
