 * Tsumiki — page chrome and the heads-up display.
 *
 * Two visual languages, on purpose, and they meet in the middle.
 *
 * The menus are Minecraft's: hard-edged panels wallpapered with the game's own
 * dirt texture, buttons with a three-pixel bevel that inverts when pressed, and
 * white text over a hard offset shadow. Nothing is rounded and nothing fades,
 * because that is the vocabulary she already reads as "this is my kind of game"
 * before she has read a single word on the screen.
 *
 * The in-world HUD is a phosphor monitor: the words themselves glow, so that
 * English on screen is always the brightest thing in the room. The bloom in the
 * shader is the other half of the same idea.
 *
 * The dirt and stone data URLs are injected as custom properties at boot from
 * the same canvas that paints the world's textures — see atlas.js.
