Maxim Dolgolyov 5381679c68 chore: консолидация незакоммиченной работы (биохимия + System Health + lab/textbooks)
Зафиксирована накопленная незакоммиченная работа рабочего дерева, КРОМЕ файлов
учебника «Химия 7» (migration 046, chemistry_7_*.html, chem7_svg.js, тест —
оставлены незакоммиченными по запросу).

Включает: модуль биохимии (ядро BIO, 3D VSEPR, химдвижок, баланс, challenges,
пути из БД), System Health Level 1 (вердикт/мониторинг), а также frontend-
страницы и lab/textbooks-правки параллельной сессии.

Maxim Dolgolyov 5c66105fc2 refactor: ещё 6 модалок → LS.modal (dashboard, theory, course)
dashboard.html: 2 → 0 
  - join-modal — вступить в класс
  - qs-modal — быстрый тест с выбором предмета + режим + кол-во

theory.html: 1 → 0 
  - new-course-modal — создание нового курса учителем

course.html: 4 → 0 
  - add-section-modal — новый раздел курса
  - edit-course-modal — редактирование курса
  - add-lesson-modal — новый урок
  - save-course-tpl-modal — сохранить курс как шаблон

Везде:
  - Inline <div class=\"modal-overlay\">...</div> → удалён
  - openX(): создаёт modal через LS.modal({content, actions})
  - closeX() удалена — _xModal.close()
  - Глобальный selectQsSubject() inline'нут как listener на body модалки
  - Enter-handler на главных inputs сохранён

Не трогаю:
  - biochem.html#lib-modal — кастомная тёмная тема, не подходит под
    светлый LS.modal без редизайна
  - library.html — 3 сложные модалки (folder-access, assign, upload)
    с tabs и dynamic state — отдельный заход
  - classes.html — modal-assign (128 строк, complex) + review-modal
  - flashcards.html — fc-modal (не modal-overlay, своя CSS)

Прогресс миграции: 12 простых модалок → LS.modal за серию (4 ранее
+ 2 ранее + 6 сейчас). 4 страницы полностью очищены от
modal-overlay. Унифицированы:
  - ESC/backdrop/focus поведение
  - z-index (9000)
  - Анимация (scale .22s)
  - Адаптив на мобилке

Maxim Dolgolyov 26ba289019 a11y: WCAG AA contrast + ARIA roles + focus management across all pages
- css/ls.css: --text-3 #8898AA → #56687A (5.1:1 contrast), min-height 44px on .btn-primary/.btn-ghost/.sb-link, new .icon-btn utility (44×44px)
- js/api.js: lsConfirm — role=dialog, aria-modal, aria-labelledby, Tab focus trap, restore focus on close; lsToast — aria-live=polite on container, role=alert on errors; live quiz — role=dialog, role=radiogroup, role=radio, aria-checked, keyboard support
- test-run.html: q-opt divs — role=radio/checkbox, aria-checked, tabindex, keyboard enter/space; confirm modal — role=dialog, aria-modal; btn-flag — aria-pressed; dots — aria-label, aria-current; touch targets 44px
- board.html: btn-del-ann — aria-label; reaction buttons — aria-label, aria-pressed
- All 18 HTML files: replace hardcoded color:#8898AA with color:var(--text-3)

Maxim Dolgolyov edb4c211a0 feat: universal sidebar via sidebar.js + stale ID cleanup
- Add js/sidebar.js: generates full sidebar HTML into #app-sidebar,
  handles role-based visibility, active link (with prefix matching),
  toggle wiring, collapsed state, board/features/notif init
- Replace <aside class="sidebar">...</aside> with <aside id="app-sidebar">
  across all 35 standard-layout pages via scripts/apply-sidebar.js
- Add notifications.js to 5 pages that were missing it
- Fix api.js initPage(): skip toggle re-wiring if data-sb-wired set,
  fix active link selector .sb-item → .sb-link
- Remove stale sbl-*/nav-admin/btn-upload-nav getElementById calls
  that crashed after sidebar replacement (lab, classes, collection,
  crossword, hangman, knowledge-map, library, pet, profile)

Maxim Dolgolyov fd29acbbdd feat: WebSocket real-time + rAF render gate + guest board + screen picker
Classroom performance:
- WebSocket server (ws-server.js) for low-latency cursor & stroke preview
  Replaces HTTP POST per event → eliminates per-message auth overhead
  Session member cache (30s TTL) avoids SQLite query per WS message
  Fallback to HTTP POST when WS not connected
- Cursor throttle reduced 100ms → 33ms (~30fps)
- Stroke preview throttle reduced 50ms → 20ms
- whiteboard.js: render() is now rAF-gated (_doRender/_rafPending)
  Multiple render() calls within one frame collapse into one repaint
  document.hidden check — zero CPU when tab is in background
  visibilitychange listener restores canvas on tab focus

Guest board:
- guestClassroom.js route: public token-based read-only access
- guest-board.html: name entry + read-only whiteboard + SSE
- SSE: addGuestClient/removeGuestClient/emitToGuests

Screen share picker:
- Discord-style modal with tab switching (screen/window/tab)
- Live video preview before confirming share
- useExistingScreenStream() in ClassroomRTC

Fullscreen exit overlay:
- #cr-fs-exit-overlay button inside cr-board-wrap
- Visible only via CSS :fullscreen selector (touchpad users)

File sharing from library:
- Teacher picks file from library, sends as styled card in chat
- crDownloadLibraryFile() fetches with Bearer auth
