/* Shared Settings button and sheet (all pages).
   Each page maps its own tokens to these:
   --s-bg  --s-text  --s-muted  --s-line  --s-accent  --s-body  and optionally --s-radius, --gs (button size)

   Hierarchy, top to bottom:
   1. sheet title            (largest, bold)
   2. group heading          (small, muted, upper case: never clickable)
   3. setting row            (label on the left, a filled button-like control on the right)
   4. page row               (name, a muted line under it, an arrow on the right) */
