docs(memory): backfill registries for docker, certbot, formation
decisions.md — log BDR-004 (containerize site with nginx:alpine behind reverse
proxy): rationale, hardening flags (read_only, cap_drop,
no-new-privileges, tmpfs), alternatives rejected (bare nginx,
Caddy/Traefik). Reference commits: 7957b04.
learnings.md — log LRN-001 (certbot --nginx matches `server_name`, not
filename): root cause was leftover `server_name autreprojet.fr`
in `sites-available/bchanot.fr`. Future check:
`grep -n "server_name" /etc/nginx/sites-enabled/*` before any
certbot install on a multi-site VPS.
journal.md — 5 lines covering docker setup, git init + remote + push,
certbot diagnose + fix, prior commit batch, and today's
feat(formation) section work (commit 1d5fbfa).
