/* =========================================================
   Etqan styles
   Brand colours sampled from the supplied identity image (docs/PLAN.md).

   System rules
   - Shape: interactive controls (buttons, segmented controls, tabs, tags) are pills.
     Cards and panels use --r-lg. Images, inputs and inner panels use --r.
     Viewer thumbnails use --r-xs.
   - Layers: header 50, skip link 100. The slide viewer is a <dialog> in the top layer.
   - Motion: transform and opacity only, custom ease-out curves, and every
     movement is removed under prefers-reduced-motion.
   - Theme: light and dark follow the system setting. The maroon brand blocks
     (hero, Signature plan, rescue card, footer) stay maroon in both.
   - No letter-spacing on Arabic text: it breaks the joined script.
