 * admin-metallic-dark.css — Phase A — Thème signature dark metallic
 *
 * Palette : graphite/titanium (surfaces) + chrome (accents) + copper rose (CTA)
 *
 * Approche :
 *   - Appliqué SYSTÉMATIQUEMENT sur data-theme="dark" (défault admin)
 *   - Coexiste avec le light mode existant (on n'écrase pas si data-theme="light")
 *   - Metallic = gradients linéaires verticaux 2-stop + highlight 1px top + shadow deep
 *   - Tous les tokens en CSS vars pour tweaks futurs
 *   - Respecte prefers-reduced-motion + focus-visible WCAG
