/**
 * launcher.css — R-Marq Arcade, direction "Cartridge".
 *
 * ONE DOM, TWO LAYOUTS. The markup is always the same — a bar, an optional
 * feature block, and sections of boxes — and a container query decides whether
 * that renders as the Stack (portrait: feature + clipping rails) or the Wall
 * (landscape and TV: one vertically scrolling grid). Rendering both would mean
 * two DOMs and twice the canvases for twenty-eight games.
 *
 * Sizes are container-relative (cqw) so a 390px phone and a 1080p television
 * share a stylesheet. --ts is the one knob that changes with viewing distance:
 * a TV is not a big monitor, it is a small screen seen from ten feet, so the
 * Fire TV shell sets --ts and everything follows.
 *
 * Palette and motion values are the design bible's, docs/launcher/README.md
 * §4 and §6. Do not invent new ones here.
