/* Focus styles — REMOVED by CHR-1 (DONI-555). Do not restore.
 *
 * This block was:
 *
 *   .btn:focus { outline: 2px solid var(--color-primary); outline-offset: 2px; }
 *
 * Two faults, and together they defeated FND-4 on the most common control
 * on the site:
 *
 * 1. `--color-primary` resolves to #f16b50 — the coral. On a coral button
 *    (`.btn--primary`) that is a coral ring on a coral field: measured
 *    1.00:1, i.e. INVISIBLE. This is the exact defect FND-4 was written to
 *    fix, and FND-4's own note calls out the coral button as the motivating
 *    case. It fixed `typography.css`'s `a:focus-visible` and did not catch
 *    this one.
 *
 * 2. `:focus`, not `:focus-visible`, at specificity (0,2,0) — so it beat
 *    the house rule `*:focus-visible` (0,1,0) AND painted a ring after a
 *    mouse click, which FND-4 deliberately designed against.
 *
 * Removing it is NOT sufficient on its own, and this is the subtle part.
 * `.btn { outline: none }` in the base rule above is specificity (0,1,0);
 * so is `*:focus-visible` in interaction.css. They tie — and buttons.css
 * is in the `component` group while interaction.css is in `base`, so
 * buttons.css loads LATER and wins the tie. Deleting only the `:focus`
 * block would therefore have left buttons with NO outline at all.
 *
 * So the house ring is restated here explicitly, from the house tokens.
 * That is exactly what interaction.css asks a component to do rather than
 * dropping to `outline: none`. It is written from the tokens, not from
 * literal values, so changing the ring centrally still changes it here.
 *
 * Verified with real Tab presses at 1440.
