Context: Owner review round — header shows no description; must come from config (flags/env only, no config file per doctrine).
Tasks:
1. `--description S` flag + `HU13_DESCRIPTION` env (flag wins, then env, then fallback: first line of wiki README? NO — fallback: empty, header hides description line). Thread through build into header + og:description + api (add `description` field to a new api/meta.json? or index only — decide: header + og + feed subtitle; keep api unchanged to avoid breaking agents).
2. Entrypoint: pass HU13_DESCRIPTION through. Dockerfile ENV default empty.
3. Demo: description text lives in DEPLOY (env on the live container), not the repo. Supervisor sets `-e HU13_DESCRIPTION="..."` on hu13-live.
4. Tests: description shown escaped (hostile `<script>` in description renders as text), absent description hides the line (no empty <p>), og:description matches.
Success rubric:
- [ ] Flag/env/fallback chain tested; escaping verified; entrypoint passes env.
Swarm: Owlette. Branch `m6/description`. Small, parallelizable.
