/* ------------------------------------------------------------ Quran slide ---
   Epic onfiremobile-r5nk2, bead .4. Loaded after styles.css. Rendered by
   slide-quran.js. Reverent and still: deep teal ground, a single soft gold
   glow, no motion, generous air. Sizes use clamp()/vmin only so a 1280x720 Pi
   and a 4K panel read the same.

   Arabic typography rules (DESIGN.md §7), each one load-bearing:
   - line-height >= 2.1: Uthmani harakat above and below collide, and the
     stage's overflow:hidden would clip the top marks of the first line.
   - letter-spacing normal, no text-transform, no font-synthesis: spacing
     breaks Arabic joining.
   - unicode-bidi: isolate, so an RTL block never reorders its LTR neighbours. */
