   - state management: `frontend/src/stores/ui.ts`
   - mounted globally in `frontend/src/App.vue`
   - card-level loading/error states are wired in `TodayView`, `MealsView`, `MealDetailView`, `IngredientsView`
+  - expired-session handling is global:
+    - token error detector in `frontend/src/utils/error.ts` emits `auth:session-expired`
+    - listener in `frontend/src/main.ts` clears session, shows info toast, and redirects to auth route
 - Frontend i18n is wired and used across new UI:
   - setup in `frontend/src/i18n/index.ts`
   - locale files in `frontend/src/locales/{sk,cs,en,es,de}.json`
   - language switcher updates locale dynamically.
   - app UI keys include (`nav`, `pageTitles`, `mealTypes`, `common`, `nutrition`, `today`, `meals`, `ingredients`, `stats`, `settings`, `ux`)
+  - `nutrition.short.fiber` exists in all locales and is used in macro badges
+  - `ux.toast.sessionExpired` exists in all locales for auto-logout flow
 - Frontend theme system is implemented:
   - centralized theme store: `frontend/src/stores/theme.ts`
   - shared toggle component: `frontend/src/components/common/ThemeToggle.vue`
   - toggle available in auth, app topbar, and settings
   - design tokens in `frontend/src/assets/css/style.css` (`:root` variables).
+- Frontend macro-badge visual system is implemented:
+  - shared component: `frontend/src/components/common/MacroBadge.vue`
+  - shared colors/tokens/styles in `frontend/src/assets/css/style.css`
+  - used in `IngredientsView`, `MealsView`, `DayTotalsCard`, and `DayMealCard`
+  - `Today` day totals card layout: kcal block on the left, macros on the right in one row
+  - macro colors:
+    - protein `#3B82F6`
+    - carbs `#F59E0B`
+    - fat `#EF4444`
+    - fiber `#10B981`
+  - style uses subtle tinted background + full-color text, pill shape (no saturated full backgrounds)
+- Frontend typography is local (no remote font CDN):
+  - `frontend/src/assets/css/style.css` uses local `@font-face` for `DM Sans` and `Space Grotesk`
+  - font files are stored in `frontend/src/assets/fonts/*.woff2`
 - App logo is served from `frontend/public/Nutrio.png` (copied from `doc/Nutrio.png`).
 - Font Awesome is installed and registered globally in `frontend/src/main.ts`.
 - Pinia is installed and configured in `frontend/src/main.ts` via `frontend/src/stores/index.ts`.
