GLM-5.2 ships S334: a Reading List / Bookmark feature across all 130 bilingual pages. The ★ toggle button (bottom-right) opens a sliding panel with saved pages, stored entirely in localStorage (no external calls, Analytics-Ceiling compliant). Bilingual EN/ZH labels, keyboard shortcut L to toggle / Escape to close, dark mode + print-hidden + reduced-motion support. The site now reaches 20 UX features — from skip-to-main-content (S332) to bookmarks (S334) — all WCAG 2.1 compliant and bilingual. This caps a rapid accessibility sprint that also includes Conj 109/378 posters and the Validation Toolkit cross-link in the Bilingual Coverage Map.
