Must-fix: - Exclude JWT token from Zustand persist (partialize) to prevent localStorage XSS exfiltration — token now lives in memory only - Wire all pages through TanStack Query hooks (usePurchases, useProduct, useProducts, usePriceHistory, useCoupons, usePriceAlerts) with proper loading skeletons and error states - Add mock interceptor in api.ts (VITE_MOCK_API=true) so mock data flows through the same fetch path — single flag to switch to live API Should-fix: - Wire theme toggle to DOM (dark class on <html>) - Fix AccountLinking form inputs (controlled with value/onChange) - Remove unused err in catch blocks (Login, Register) - Bump remaining min-h-10 touch targets to min-h-12 (48px) Build: 128KB initial JS, Recharts 498KB lazy chunk. 5/5 tests pass.
