/* ==========================================================================
 * GHZYLAB ARCADE — shared chrome (switcher overlay + hub page).
 *
 * Deliberately SELF-CONTAINED: Buggy Run and Potion Sort have different design
 * languages and different CSS variable names (--accent/--text vs --gold/--ink),
 * so this file defines its own --arc-* tokens instead of borrowing either. That
 * way the switcher looks identical in both games and cannot break when one
 * game's palette changes.
 *
 * Every colour has one definition per theme block; nothing is defined only
 * inside a media query.
