Stand up the full SQLite content layer: all 7 tables from the authoritative
schema with WAL + foreign-keys enforced per-connection, entity dataclasses
plus row mappers, hand-rolled versioned migrations tracked in
schema_migrations, and an idempotent Python seed (system user + welcome
post + About page).
Add a Markdown->HTML service using markdown-it-py with a strict bleach
allowlist (tables intentionally omitted on both sides). Add a typed
in-process TTLCache[K,V] and wire it into real DB-backed PostService and
PageService, both exposing invalidate_all() for Phase 4 admin writes.
Rewire / and /about to read from the DB; homepage renders the seeded
welcome post, About renders page.title + sanitized body_html_cached.
Update the Phase 1 route tests accordingly.
Mark Phase 2 complete in docs/ROADMAP.md.
