/* ───────────────────────────────────────────────────────────────────
 * Quota-economy UI (2026-04-29)
 *
 * Replaces the credits-balance display with a quota-aware UI for
 * users in the QUOTA_MODEL experiment. Until Phase 6 (D-day), this
 * stylesheet only takes effect when window._experimentFlags.quota_model
 * is true — JS adds `html.quota-mode` and the CSS scoped under it.
 *
 * Header changes:
 *   - The credits pill (#navCredits) is hidden
 *   - A single tier pill (#navTierPill) is shown — Free / Basic / Pro / Pro+
 *
 * Cost labels (Phase 3b+):
 *   - .regen-cost (the "15" badge on image buttons) is hidden
 *   - .regen-quota (a new sibling element) is shown with "used/cap"
 *
 * Everything outside `html.quota-mode` is untouched.
 * ───────────────────────────────────────────────────────────────── */
