   OKLCH / DISPLAY-P3 ACCENT PALETTE (PROGRESSIVE ENHANCEMENT)
   ═══════════════════════════════════════════
   The @theme block above keeps the original sRGB hex values, which
   Tailwind reads at build time and which serve as the fallback for
   sRGB monitors and browsers without OKLCH support.

   When the browser understands oklch(), we redefine the SAME vivid
   accents + node-type colors using their OKLCH equivalents. These are
   faithful conversions of the hex values (same hue/chroma identity);
   on a wide-gamut display-p3 monitor they render more saturated while
   reading as the same color. The void/abyss/surface neutrals are left
   untouched — only the vivid accents benefit from the wider gamut. */
