"""安全每日一题 (security daily quiz).

A gamified daily security-awareness quiz: one question a day, a streak for
answering correctly, an all-company leaderboard, and a compliance-coverage
read so the auditor can evidence security-awareness participation. The question
bank is seeded with a curated starter set, editable by admins, and expandable
via the org's existing LLM connector (graceful no-op when no key is configured).
