/* WORLD — an earlier scripture and the Quran, side by side.
   Mobile-first (390px design width), tokens only, so all five skins work.

   LAYOUT LAW (mirrors world.js):
   - .wd-left is the earlier scripture, .wd-right is always the Quran. The grid
     never reorders them: no direction, no order, no row-reverse anywhere below.
   - .wd-cite is sticky and is never given a hidden, collapsed or truncated state.

   Phone (<700px): the two panels stack and the segment toggle jumps between them.
   Nothing is hidden — both panels and both citation bars stay in the page.
   Tablet/desktop (>=700px): the reader breaks out of the 560px column and the
   panels sit in two independently scrolling columns. */
