 - **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.

+### 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.
