 * Catersoft Help — Article Theme
 * Shared styles cho 4 article trong feature `thuc-don-tuan/`:
 *   - thuc-don-tuan.html         (entry, how-to)
 *   - sao-chep-tu-tuan-khac.html (how-to)
 *   - in-thuc-don-tuan.html      (how-to)
 *   - xoa-thuc-don-tuan.html     (admin-only)
 *
 * Convention:
 *   - Variables (light + dark via prefers-color-scheme)
 *   - Article anatomy: topbar, hero, toc, sections (s), steps,
 *     note, tip, branching, faq, next-steps, related, footer
 *   - Components: glossary v2 (3-group), compare cards,
 *     ui-shot figures, troubleshoot tables
 *   - Optional danger family (xoa-style files): .danger-banner,
 *     h2.danger, ol.steps.danger, .note.danger, etc.
 *
 * Khi rollout sang module khác (kho/, ke-toan/, nhan-su/):
 *   `git mv` lên `_assets/` ở root v4-user-guide-docs + sửa path
 *   trong các <link> tag (currently `./theme.css`).
