/**
 * Rewards & Progression — role-unlock flows (matrix rows 12.1.1 / 12.1.2 / 12.1.3).
 *
 * Goal: prove that the Rewards page renders the three unlock taxonomies the
 * matrix tracks — activity-based, integration-based, plan-based — by
 * pre-seeding `mockBehavior.rewardsScenario` for each case before the
 * Rewards page fetches `/rewards/me`.
 *
 * Per-case strategy:
 *  - 12.1.1 activity-based unlock: `rewardsScenario=activity_unlocked` →
 *    streak achievement marked unlocked; assert "1 of 3 achievements unlocked"
 *    + "Unlocked" label on the streak card.
 *  - 12.1.2 integration-based unlock: `rewardsScenario=integration_unlocked`
 *    → discord membership=member, assignedDiscordRoleCount=1; assert
 *    "Joined the server" copy + Discord achievement card unlocked.
 *  - 12.1.3 plan-based unlock: `rewardsScenario=plan_unlocked` → plan=PRO,
 *    hasActiveSubscription=true; assert the plan-tier achievement is the
 *    unlocked one in the snapshot reflected in the UI.
 *
 * The mock has to be primed BEFORE the Rewards page mounts: `Rewards.tsx`
 * fetches once on mount via `useEffect`. Each `it()` resets behavior,
 * primes the scenario, then navigates fresh — the SPA hash router unmounts
 * the previous Rewards instance, so re-navigating is enough to re-trigger
 * the load (no full page reload needed).
 *
 * Mac2 skipped — Rewards content is rendered in the WKWebView and the
 * Appium helpers do not yet expose the `Rewards` bottom-tab label cleanly.
 * The Linux tauri-driver run is the source of truth for this spec, matching
 * `whatsapp-flow.spec.ts` / `slack-flow.spec.ts` / `insights-dashboard.spec.ts`.
