/* ---- Settings ----
   STROKE RULE, Aug 13 2026 — proposed, pending Kim's approval.

     A group of rows is expressed by a surface and hairline dividers.
     It is never expressed by an outer box.

   Stroke is reserved for things a person acts on directly — inputs, buttons,
   selects — plus overlays, which already get elevation. In-flow grouping
   surfaces (settings, FAQ, cards, tables) get background + dividers and no
   border. This is the Apple Settings / Stripe dashboard pattern.

   Why the old treatment was wrong on two counts: a 1.5px near-black border is
   heavier than any content inside it, so the container outranked the content;
   and box-shadow on an in-flow surface contradicts CLAUDE.md's own rule that
   only overlay surfaces get elevation.

   The one sanctioned exception: a surface that must be distinguished from an
   identical sibling directly beside it (side-by-side compare, selected state).
   Nothing in the app does that today. */
