/**
 * Mythkeeper's Room — shell styling.
 *
 * The canvas is letterboxed by `resize()` in js/render.js: every frame it fits
 * the largest 960×540 box inside #stage and sets the canvas box exactly, so the
 * declared ratio in the registry, the CSS box and the drawing buffer always
 * agree — a 3D view that is stretched to its container is a room whose walls
 * lean. Everything clickable lives outside the canvas: the journal, the
 * pockets, the buttons and the walking pad. See docs/GAME_BUILDING_AGENT.md §2.
 *
 * Dark oak, one warm accent, tabular numbers: the mood of the room in the
 * chrome around it.
