"""Aggregated curated bank for 安全每日一题 (security daily quiz).

Content lives per category-group under ``seedbank/`` (authored/reviewed
independently); this module concatenates them and dedupes by prompt.
Inserted idempotently by migration 417 (existing questions are skipped),
so the same curated bank converges across every environment without
disturbing questions admins have since edited.

Each entry: prompt / options (4, keyed A–D) / correct_key / explanation /
category / qtype. Every "correct" answer is genuine security best practice.
