"""安全宣贯 — the security-awareness domain.

Turns "we sent a security email once" into a continuous operating loop
with an evidence trail: a hosted content library (comics / articles / links, three
languages), an exposure ledger recording who was actually shown what,
and — in the PRs that follow — campaigns that target an audience over
Feishu / mail / the in-app inbox, per-person acknowledgement, an ambient
surface, and a compliance control that reads coverage off all of it.

Nothing here imports another domain: cross-domain work goes through
``app/core/coordinators`` and the notification outbox, per the platform
rules in CLAUDE.md.
