/**
 * Settings → Health Score: the surface that decides which pillars count.
 *
 * Everything asserted here goes through stable `data-slot` / `data-*`
 * attributes rather than viewport-dependent text, so the spec keeps working
 * at any width and in any locale (only the copy assertions read English, and
 * the suite pins the English locale through the storage state).
 *
 * The refusal case is driven through the REAL write. Deselecting every
 * pillar genuinely fails the server's breadth rule, and a refused write
 * persists nothing, so the case leaves the shared account exactly as it
 * found it. Mocking the 422 would have proved that the page can render a
 * message, not that the rule is enforced or that the page reads the reason
 * the server actually sends.
 *
 * The analytics read IS mocked, because it is the page's secondary read and
 * the states it drives — waiting for data, safety signposting — depend on
 * what the seeded account happens to hold. Fixing it makes those two rows
 * deterministic without touching the write path under test.
