-
-- `MEDIA_STORAGE_ROOT` per la root `storage_media` usata dal backend (`original/`, `public/`, `private/`)
-- `SHOP_STORAGE_ROOT` per la root `storage_shop` usata dal backend per i modelli dei prodotti shop

-- `MEDIA_UPLOAD_MAX_FILE_SIZE_BYTES` per il limite per asset immagine

-## Media pubblici
-
-Il backend salva sempre l'originale in `storage_media/original/` e precomputa le varianti pubbliche in `storage_media/public/`. La cartella `storage_media/private/` è predisposta per asset non pubblici.
-
-Nel deploy Docker i volumi attesi sono `/mnt/cache/appdata/print-calculator/${ENV}/storage_media:/app/storage_media` e `/mnt/cache/appdata/print-calculator/${ENV}/storage_shop:/app/storage_shop`.
-
-Nginx non deve passare dal backend per i file pubblici. Configurazione attesa:
-
-```nginx
-location /media/ {
-    alias /mnt/cache/appdata/print-calculator/${ENV}/storage_media/public/;
-}
-```
-
-Usage key iniziali previste per frontend:
-
-- `HOME_SECTION / shop-gallery`
-- `HOME_SECTION / founders-gallery`
-- `HOME_SECTION / capability-prototyping`
-- `HOME_SECTION / capability-custom-parts`
-- `HOME_SECTION / capability-small-series`
-- `HOME_SECTION / capability-cad`
-- `ABOUT_MEMBER / joe`
-- `ABOUT_MEMBER / matteo`
-- riservati per estensioni future: `SHOP_PRODUCT`, `SHOP_CATEGORY`, `SHOP_GALLERY`
-
-Operativamente:
-
-- carica i file dal media admin endpoint del backend
-- associa ogni asset con `POST /api/admin/media/usages`
-- per `ABOUT_MEMBER` imposta `isPrimary=true` sulla foto principale del membro
-- home e about leggono da `GET /api/public/media/usages?usageType=...&usageKey=...`
-- il frontend usa `<picture>` e preferisce AVIF/WEBP con fallback JPEG, senza usare l'originale
-- nel back-office frontend la gestione operativa della home passa dalla pagina `admin/home-media`
 
 ## Troubleshooting
 
 ### Percorso OrcaSlicer
 Assicurati che `slicer.path` punti al binario corretto. Su macOS è solitamente `/Applications/OrcaSlicer.app/Contents/MacOS/OrcaSlicer`. Su Linux è il percorso all'AppImage (estratta o meno).
 
-### FFmpeg e media pubblici
-Verifica che `MEDIA_FFMPEG_PATH` punti a un `ffmpeg` con supporto JPEG, WebP e AVIF (encoder + muxer AVIF). Nel container backend il default è `/usr/local/bin/ffmpeg-media`: usa `/usr/bin/ffmpeg` se già compatibile, altrimenti installa un fallback statico con supporto AVIF. Se gli URL media restituiti dalle API admin non sono raggiungibili, controlla che `APP_FRONTEND_BASE_URL` punti al dominio corretto, che `location /media/` sia esposto da Nginx e che il volume `storage_media` sia montato correttamente.
-
 ### Database connection
 Verifica le credenziali in `application.properties`. Se usi Docker, puoi passare `DB_URL`, `DB_USERNAME` e `DB_PASSWORD` come variabili d'ambiente.
-
-### Deploy e traduzioni OpenAI
-Nel deploy Gitea la chiave OpenAI deve stare nel secret `OPENAI_API_KEY`. La pipeline la aggiunge al file `.env` dell'ambiente durante il deploy e il container backend la riceve come variabile runtime. I file `deploy/envs/*.env` restano per i valori specifici di `dev/int/prod`.
