- SSRF-safe fetcher: public IPs only, connects to the checked address,
redirects re-validated, size/time limits, honest user agent
- schema.org/Recipe JSON-LD extraction (graphs, HowToSections, ISO
durations, yields, keywords, images) without extra dependencies;
AI fallback on plain page text when no structured recipe exists
- Instagram: one login-free request to the public embed page; when
Instagram withholds the caption, the import page explains how to paste
the text or import a screenshot instead
- Suggested source photo can be downloaded and attached on save
- Text import works without AI (text becomes the description)
- Installable PWA with manifest, icons and Android share target
- Offline tests for SSRF rules, parsers, Instagram and import views

- recipes/ai.py: Chat Completions with strict JSON schema (Structured
Outputs), Pydantic re-validation, plausibility clamping, prompt treats
input as data only
- "Mit KI aufbereiten" on create/edit form returns an editable draft
- Import page: photo/screenshot (vision, downscaled JPEG, not stored) and

- Clear UI messages for timeout, rate limit, quota, auth, model and
connection errors; without OPENAI_API_KEY AI features show a notice
- Optional per-user and global daily AI limits (default unlimited)
- Tests for response parsing, schema strictness, error mapping, views
