 * store-account.thresholdx.net — B2C account page (#985, spec #833)
 *
 * Design doctrine: threshold-documents/doctrine/design/
 *   - No borders (2026-07-03 ruling): tone separates, not lines.
 *   - Radii ladder: 8px buttons/cards, 10px large panels, 12px modals, 4px tags.
 *   - Lapis is the CTA/interactive accent; Threshold Blue is the canvas.
 *   - Basier Circle self-hosted (customer-facing web surface).
 *   - Focus rings stay (accessibility floor). Reduced motion respected.
