- store records in SQLite via built-in node:sqlite, no native deps - wrap DB reads in await io() so they stay out of the static shell - add CRUD pages backed by Server Actions with per-request data - generate managed config and restart container via Docker socket - add /resolve page to query dnsmasq for A and CNAME records - add Dockerfile and compose setup with shared config volume
