+
+### Added
+- **AI price estimation for shopping list** — Each item on the Bring! shopping list now shows an estimated retail price badge (per unit and total). Prices are fetched from Gemini AI and cached server-side for 3 months (`PRICE_UPDATE_MONTHS`). The running estimated total is displayed both in the shopping tab and as a green pill badge on the dashboard stat card.
+- **Dashboard price total badge** — The shopping stat card on the dashboard shows a green `ca. €X.XX` badge (top-right, same position as the old urgency badge). It updates in real-time as prices are calculated and persists across navigation via `sessionStorage`.
+- **Background price refresh** — Prices are fetched silently every 2 minutes even when not on the shopping tab, keeping the dashboard badge current without user interaction.
+- **Smart quantity estimation** — The price payload uses `smart_shopping` data (consumption patterns) to send the correct buy quantity per item; falls back to Bring! spec parsing, then to `qty=1, unit=conf` for manually-added items.
+
+### Fixed
+- **`stat-price-total` not visible on dashboard** — The total was only computed when `shoppingItems` was populated (i.e. shopping tab had been visited). Now uses `sessionStorage._pricetotal` as fallback so the badge is visible immediately on any page.
+- **Price bar reloading on every tab switch** — `renderShoppingItems` now checks if ALL items are already cached with matching qty/unit; if so, it applies prices from cache instantly with no loading bar or API call.
+- **`stat-price-total` real-time update** — Dashboard stat now increments as each individual item is priced (not only after the entire fetch completes).
+- **Broken emoji in `log.title`** — Corrupted `\uFFFD` character in `it.json` and `de.json` replaced with `📒`.
+- **`PRICE_CACHE_PATH` undefined crash** — Server-side constant was used inside functions that were called before the define; moved define to the very top of `api/index.php` (line 19). Affected: all `get_shopping_price` and `get_all_shopping_prices` calls from 16:33–16:40 on 2026-05-07.

 ## 🌍 Recent Updates
 
+- **AI price estimation for shopping list** — Each Bring! shopping item now shows an estimated retail price badge (unit price + total). Prices are fetched via Gemini AI, cached server-side for 3 months, and stored client-side in `sessionStorage` to survive navigation. The dashboard shopping stat card shows a live green `ca. €X.XX` badge that updates in real-time as prices are calculated — even in background when you're on another tab.
 - **Kiosk v1.7.0: OTA update system** — "Cerca aggiornamenti" button in Settings triggers a forced GitHub release check; new `installUpdate()` JS bridge calls Android `DownloadManager` directly (lockTask mode blocks external browser links); graceful degradation for older APKs with manual instructions. Automatic OTA check every 6 hours with native update banner.
 - **Kiosk: consistent APK signing** — Project keystore (`evershelf.jks`) committed to the repo; every build — local or CI — now produces an APK with the same signature, eliminating "APK incompatible / signature conflict" errors on OTA update.
 - **GitHub Actions: auto-publish kiosk APK** — On every push to `main` that touches `evershelf-kiosk/`, Actions builds the APK and publishes a versioned semver release (`kiosk-X.Y.Z`) plus updates the `kiosk-latest` alias. No more manual release uploads.
