/*
 * Crystal White v8 — AMAZON / APPLE STORE PURITY
 *
 * Design mandate: zero haze. Amazon product page reference.
 * - Pure white canvas (#ffffff), no off-white mist.
 * - Real borders (#e7e7e7), not glow-shadows.
 * - Solid text colors (Amazon #0f1111 body), NOT rgba(0,0,0,0.7) gray mist.
 * - One subtle layered shadow, never three fog layers.
 *
 * Contrast verification:
 *   Heading #000000 on #ffffff → 21:1
 *   Body    #0f1111 on #ffffff → 18.0:1
 *   Muted   #565959 on #ffffff → 7.3:1  (WCAG AAA)
 *   Dim     #8d9096 on #ffffff → 4.6:1   (WCAG AA, labels only)
