/* ============================================================================
 * VYNUMO — BLOODCRIMES THEME
 * ============================================================================
 * Optional theme (data-theme="bloodcrimes"). The default Vynumo themes and
 * their identity are untouched: this file only applies when the theme is
 * explicitly selected, which the BloodCrimes adapter does automatically in
 * BloodCrimes mode.
 *
 * Design source of truth: BloodCrimes tokens
 *   (assets/css/bloodcrimes/tokens.css — neo-noir crime RPG).
 *   bg #0B0C10 · surface #141418 · crimson #B51220 · gold #C99A38
 *
 * RULES OBSERVED HERE
 *   1. The 4x4 board stays the most readable thing on screen. Decoration is
 *      always edge-anchored, low-alpha, and never sits over a value.
 *   2. Low-value tiles stay plain. Only 128+ gains real ornament, so early
 *      play reads as a clean board instead of confetti.
 *   3. Motion is short (<= 220ms) and fully disabled under
 *      prefers-reduced-motion.
 * ========================================================================== */
