The first MINOR after 1.0.0: send-only DMARC guidance in the panel, AGPL packaging on every page, and an internal split of `internal/web` ahead of domain-admin work. Upgrading runs one SQLite migration (empty defaults; existing DNS guidance is unchanged until you set a report address). Changed: - `internal/web` split into subpackages (`web/view`, `web/auth`, `web/validate`, Added: - panel: DMARC guidance for send-only relays — the suggested `_dmarc` record - AGPL packaging hygiene: [NOTICE](NOTICE) names the copyright holder and the - [docs/roadmap.md](docs/roadmap.md) — candidate item **visual-style** (panel Full detail: CHANGELOG.md (1.1.0).
