 * axe does not catch this - focus visibility is not reliably automatable - so it is covered
 * by a keyboard test in e2e/tests/accessibility.spec.ts instead.
 *
 * The ring is two-tone on purpose. WCAG 1.4.11 wants 3:1 against what the indicator sits
 * on, and no single colour manages that against both a navy button and the near-white page:
 * gold is 5.4:1 on navy but 2.9:1 on the page. So a white halo separates the ring from the
 * button, and a navy ring reads against the page at 15.4:1 and against the gold button at
 * 5.4:1.
