- **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.

## [1.7.19] - 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).
