With yesterday's cron infrastructure fix in place, both daily jobs got
to actually execute today and revealed bugs that had been hiding behind
the silent failures.
1. Wiki export crashed on docs whose body starts with `---` (markdown
horizontal rule). matter.stringify(str, data) re-parses str as if
it might already contain frontmatter, so a leading `---` makes
gray-matter try to YAML-parse the body and choke on the first
`Title: subtitle` colon. Pass {content: str} instead — the parser
only runs on bare strings, so an object skips the re-parse path.
2. outline-backup.sh referenced docker container names `outline-postgres`
and `outline`, but DokPloy names containers `${project}-${service}-1`,
so the backup got `Error response from daemon: No such container`.
Derive names from $APP_NAME (set to the compose project name) with
POSTGRES_CONTAINER / OUTLINE_CONTAINER overrides for portability.
Strip the Nuxt 4 static site and replace with Docker Compose config
for self-hosted Outline wiki (Outline + PostgreSQL 16 + Redis 7).
Adds nginx reverse proxy with WebSocket support and CSS injection,
migration script for existing markdown articles, backup script,
and starter theme CSS.
