 - **Recipe scraps tips** — During cooking steps, detect "waste" generated (peels, cores, bones, eggshells, coffee grounds, citrus zest, etc.) and surface AI-powered tips on how to reuse them (compost, natural cleaner, broth, candied peel, etc.). Could be shown as an optional collapsible hint card below the step that generates the scrap.
 
+## [1.7.20] - 2026-05-20
+
+### Added
+- **Startup health check** — During the splash screen, the app now runs a comprehensive server-side diagnostic before loading: PHP version, required extensions (pdo_sqlite, curl, mbstring, json), `data/` directory writability, SQLite database connection and table integrity, `.env` file presence, Gemini AI key and Bring! token. Results are displayed as an animated checklist (✅ / ⚠️ / ❌). Critical failures (DB, extensions, data dir) block the app with a clear error message and a "Retry" button — the app never starts silently broken. Non-critical warnings (missing Gemini key, Bring! token) are shown as amber items but do not block startup.
+- New `?action=health_check` PHP endpoint (early-exit, no rate-limit, no auth).
+- New translation keys `startup.*` in all 5 languages (IT, EN, DE, FR, ES).
+
+## [1.7.19] - 2026-05-19
+
+### Added
+- **Zero-waste tips during cooking** — When cooking mode is active, a ♻️ card appears below each step that generates reusable scraps (peels, cooking water, egg whites, cheese rinds, bread crusts, vegetable tops, etc.). Gemini generates the tips as part of the recipe JSON at no extra API cost. Tips are dismissible per-step and reset on recipe restart. Opt-in toggle in Settings → Zero-waste tips (default OFF). Resolves [#76](https://github.com/dadaloop82/EverShelf/issues/76).
+- New translation keys `cooking.zerowaste_*` and `settings.zerowaste.*` in all 5 languages (IT, EN, DE, FR, ES).
+
+## [1.7.18] - 2026-05-19
+
+### Added
+- **Dark mode** — New theme selector in Settings (Appearance card): **Off (Light)**, **On (Dark)**, **Auto (follows system)**. Applied immediately on page load to prevent white flash. Resolves [#78](https://github.com/dadaloop82/EverShelf/issues/78).
+- **Export inventory** — New 📤 button in inventory page header opens a modal to download the inventory as **CSV** (UTF-8 with BOM, Excel-compatible) or open a **print-ready HTML page** (auto-triggers print dialog for PDF). Export card also available in Settings tab. Resolves [#64](https://github.com/dadaloop82/EverShelf/issues/64).
+- `translations/de.json`: fixed missing `log.recipe_prefix` key.
+
+## [1.7.17] - 2026-05-19
+
+### Added
+- **French translation (🇫🇷 Français)** — Complete `translations/fr.json` with all 1049 translation keys. Resolves [#77](https://github.com/dadaloop82/EverShelf/issues/77).
+- **Spanish translation (🇪🇸 Español)** — Complete `translations/es.json` with all 1049 translation keys. Resolves [#77](https://github.com/dadaloop82/EverShelf/issues/77).
+- Language selector in Settings now shows all 5 languages: 🇮🇹 Italiano, 🇬🇧 English, 🇩🇪 Deutsch, 🇫🇷 Français, 🇪🇸 Español.
+- Default fallback language changed from Italian to English (for users with unsupported browser locale).
+- Setup wizard "Done" screen and navigation buttons localised for French and Spanish.
+
+## [1.7.16] - 2026-05-17
+
+### Added
+- **Barcode scan history** — Last 20 scanned products are stored server-side (SQLite `app_settings`) and shown as chips in the scan page (`#scan-recents-chips`). Tapping a chip selects the product directly — no need to scan again. Resolves [#68](https://github.com/dadaloop82/EverShelf/issues/68).
+- **Full server-side user-data centralisation** — All user preferences previously siloed in `localStorage` per-device are now synced to the server via `app_settings_save` and loaded back at startup via `app_settings_get`. Affected data: shopping tags, pinned Bring! items, location preferences (use/move), auto-added Bring! entries, Bring! purchased blocklist, no-expiry dismissed products. Data is now shared across all devices (desktop, phone, kiosk, Android app).
+- **One-time localStorage migration** — On first load, any data found in the old localStorage keys (`shopping_tags`, `_userPinnedBring`, `_prefUseLoc`, `_prefMoveLoc`, `_autoAddedBring`, `_bringPurchasedBlocklist`, `_noExpiryDismissed`, `evershelf_scan_recents`) is automatically migrated to the server and the local keys are removed.
+
+## [1.7.15] - 2026-05-16
+
+### Added
+- **Full i18n audit** — Comprehensive sweep of all user-visible strings in `app.js` and `index.html`. 25+ new translation keys added across `it.json`, `en.json`, `de.json`, covering: vacuum toast, TTS voice controls, timer step labels, product note labels, error messages, expiry form, barcode hint, category select placeholder, cooking step fallback, `form.select_placeholder`, `btn.yes_short`/`no_short`, `add.vacuum_question`, `add.vacuum_saved`, `move.vacuum_seal_rest`, `cooking.step_fallback`, `error.prefix`/`unknown`, `product.select_variant`, and more.
+- **Splash screen redesign** — Logo displayed prominently, spinner below, app version shown at the bottom; version label injected dynamically at boot time so it never gets out of sync. Minimum 3-second display duration enforced: `_splashStart` is recorded before `DOMContentLoaded`; the fade-out is delayed by the remaining time if the app loads faster than 3 s.
+- **Demo GIF in README** — `assets/img/demo.gif` (processed at 2× speed, ~36 s) added to the `## 📸 Screenshots` section.
+- **`pz`/`conf` unit labels translated** — "pz" now shows as "pcs" in English and "Stk" in German; "conf" shows as "pkg" / "Pkg". All `unitLabels` objects in JS now use `t('units.pz')` / `t('units.conf')`.
+
+### Fixed
+- **Camera button (📷) opened kiosk SettingsActivity on Android** — The native `btnSettings` ImageButton in the kiosk layout was positioned `top|end` with `alpha=0.12` (nearly invisible), sitting directly on top of the HTML scan button in the webapp header. Every tap on the 📷 button was intercepted by the native View and opened `SettingsActivity`. Fixed: moved `btnSettings` to `bottom|end` (above the bottom nav bar, `marginBottom=80dp`) and increased `alpha` to `0.28` so it is clearly separate from the header. Kiosk versionCode bumped to 16.
+- **Camera button (📷) opened settings on Android Chrome/Brave** — `pointerleave` fired before `pointerup` when finger drifted slightly, cancelling the long-press timer and leaving the browser to dispatch a synthetic `click` that bubbled to an unintended handler. Fixed: added `setPointerCapture` (prevents `pointerleave` during touch) and `preventDefault` (blocks synthetic click); replaced `pointerleave` with `pointercancel` handler. Added `touch-action: manipulation` to `.header-scan-btn` CSS.
+- **Logo white background on splash screen** — Re-processed both `logo.png` and `logo_icon.png` with fuzz 35% alpha extraction, removing the white background that was visible against the dark splash background (`#0f172a`).
+- **Recipe button label** — Shortened to "Ricetta" / "Recipe" / "Rezept" for compact display in the inventory quick-action modal.
+- **Quantity decimal precision** — `qtyNum` in recipe/cooking ingredient buttons and `conf` fallback display in inventory cards now limited to 1 decimal place (was showing 7+ decimal places from raw AI output, e.g. `0.25353223 conf`).
+- **"Errore" / "Error" fallback strings** — All remaining Italian hardcoded `'Errore'` fallbacks in `showToast()` calls replaced with `t('error.generic')`. Italian fallback strings removed from buttons that already used `t()`.
+- **README Italian phrases** — "La quantità è giusta (2 pz)", "🤖 Spiega", "Latte / Affettato / Panna da cucina", "Buon appetito!", "L'ho buttato" replaced with English equivalents in the README.
+- **Appliance chips translated** — `renderAppliances()` now shows translated names (e.g. "Air fryer" in EN, "Heißluftfritteuse" in DE) for all known canonical Italian appliance names via `_applianceDisplayName()` lookup. `addApplianceQuick` toast no longer hardcoded Italian. Remove-button title translated.
+- **Gemini API key not preserved on settings save** — `saveSettings()` was overwriting `s.gemini_key = ""` when the Gemini input field was empty (it is intentionally not pre-populated for security). Key is now preserved if the input is blank. `_geminiAvailable` is re-fetched from the server after every settings save so the recipe buttons reflect the real state immediately.

 ## ✨ Features
 
+> ♻️ **New in v1.7.19 — Zero-waste cooking tips**
+> During cooking, EverShelf shows a contextual ♻️ tip card for each step that generates reusable scraps — peels, cooking water, egg whites, cheese rinds, bread crusts and more.
+> Tips are generated by Gemini *as part of the recipe* at zero extra API cost, shown inline in cooking mode, and dismissible per step.
+> Enable the toggle in **Settings → Zero-waste tips** (default: off).

+Feature requests, bug reports and planned work are tracked in the [**EverShelf Roadmap**](https://github.com/users/dadaloop82/projects/2) GitHub Project.
-- [ ] **Cooking mode — 3D wheel JS** — swipe navigation, gyroscope tilt, haptic feedback
-- [ ] **Cooking mode — step timers** — auto-detect "X minutes" in recipe steps, countdown + alert
-- [ ] **Push notifications** — daily expiry alerts via PWA Service Worker + VAPID
-- [ ] **Quick search / quick-add bar** — always-visible search above the nav, PWA shortcuts
-
-### Medium Priority
-- [ ] **Receipt OCR → bulk add** — photo of receipt → Gemini Vision → auto-fill inventory
-- [ ] **CSV/JSON export & import** — download/upload inventory from Settings
-- [ ] **Custom storage locations** — user-defined locations beyond Fridge/Freezer/Pantry
-- [ ] **Multi-user support** — PIN-based user distinction, action log with user label
-- [ ] **AI optimal purchase prediction** — suggest "buy X units of Y within Z days"
-- [ ] **Price history sparklines** — per-product price chart from the AI cache data
-
-### Low Priority / Nice to Have
-- [ ] **Dark mode** — CSS custom properties are already structured to support it
-- [ ] **Full offline mode** — Service Worker cache to show inventory read-only when server is down
-- [ ] **French & Spanish translations** (`fr.json`, `es.json`)
-- [ ] **Swipe actions on inventory rows** — swipe left to use/discard, right to edit
-- [ ] **PHP unit tests** — PHPUnit coverage for shelf-life, price calc, and key helpers
-
-### Completed ✅
-- ✅ AI price estimation in shopping list
-- ✅ Server heartbeat + offline banner
-- ✅ In-app bug reporter → automatic GitHub issue creation
-- ✅ Cooking mode (start, steps, 3D wheel CSS)
-- ✅ Kiosk ⚙️ Settings overlay button (replaces Android native button)
-- ✅ Adaptive consumption anomaly detection
-- ✅ CI/CD pipeline (PHP lint, JS lint, Docker build, Trivy security scan)
