/*
 * Hartii Biome — the rooms.
 *
 * READ THIS FIRST: the default styles below describe a NORMAL SCROLLING PAGE. Every room is an
 * ordinary section, stacked, fully readable. `html.js-rooms` (added by rooms.mjs, and never under
 * prefers-reduced-motion) is what turns the page into a fixed 3D stage you swipe through. So no
 * JS, an old browser and reduced motion all get complete content — nothing is only reachable by
 * swiping.
 *
 * Depth is built from two independent perspectives rather than one fragile preserve-3d tree:
 * each room's set dressing (.room-bg) and content (.room-inner) carry their OWN perspective, so a
 * room is a "painting with depth" that the stage can then rotate as a single plane. That survives
 * Safari's preserve-3d + overflow bugs, and it is cheaper to composite on a phone.
