**Woo credential setup (once per store):**
1. Store must already be on **HTTPS**. WordPress will not offer Application
Passwords over plain HTTP.
2. Create a dedicated low-privilege WordPress user (shop manager, or custom role
with product create/edit + media upload). Do not reuse an admin login.
3. Sign in as that user → **Users → Profile → Application Passwords** → generate
a password for "SlabUploader".
4. Enter the username + application password in the app Settings UI. FastAPI
stores them AES-GCM encrypted. Browser never keeps them.
5. Rotate by revoking the old application password in the WP profile and
re-entering a new one in Settings, then `test-woo`.
Key rotation (AES): `SLAB_AES_KEY` change requires re-encrypting settings —
provide `python -m app.security.rekey NEW_KEY` (reads old key from env
`SLAB_AES_KEY_OLD`, decrypts, re-encrypts, updates). Documented in playbook §7.
