   --------------------------------------------------------------------------
   ADDITIVE / DECORATIVE ONLY. Loaded AFTER main.css (cascades on top).
   - No layout changes on major containers (.nav/.section/.hero/.footer/grids)
   - RTL-safe: direction-symmetric or logical properties everywhere
   - Grain, glows, gradients = backgrounds/transforms/pseudo-elements only
   - Fixed overlays: z-index <= 3 + pointer-events:none (never blocks clicks)
   - prefers-reduced-motion: all premium motion disabled
   - Depends on tokens from main.css (--c-magenta, --c-black, --ease-out ...)
     and on the parent <link> adding 'Space Grotesk' to the Google Fonts URL.
