- lib/toast.tsx (renamed from .ts for JSX): new showToast.undo(message, onUndo, ms=5000) helper. Inline 'Undo' button dismisses the toast and fires onUndo. Note: react-hot-toast 2.6 lacks onClose/onDismiss, so expiry is silent — same effective behavior as confirm() declined. - Dashboard.handleDelete: captures the full MealPlanItem before the DELETE so Undo can re-fire meals.generateItem(planId, dayOfWeek, mealType) and refill the slot (recipe may differ — see plan R4). - Pantry.handleRemove: fully reversible — Undo re-fires pantry.add with the original ingredient_id, quantity, and unit. New removeId state scopes the spinner to the clicked row. - Both confirm() call sites removed. - App.tsx Navigation: whitespace-nowrap + px-2 sm:px-3 so all 4 links fit on one line down to 360 px. aria-current='page' on the active link. <nav aria-label='Primary'>, <main id='main-content'>. - components/ui/Badge: optional icon and aria-label props. Dashboard approval-status Badge passes aria-label='Approval status: approved' (or the current value) so screen readers don't rely on color alone. - ErrorBoundary already mounted at App.tsx:42 — verified, no code change. - Review/sprint3-verification.md (new) + Review/ui-nielsen-audit.md and fix-ui-audit.md updated with Sprint 3 status and deploy steps. Build: npm run build (tsc + vite) green. tsc 0 errors.
