- webcam capture resolution/quality configurable in admin settings (defaults 640x480 / 0.92)
- enhance photo modal in journal: original vs preview with sliders (brightness, contrast, saturation, sharpen) and auto-levels button
- new endpoint PUT /api/entries/:id/photo/enhance replaces photo, cleans old file and thumb
- sharper HEIC conversion (0.92) and webp thumbnails (85)
- worker: fail explicitly on empty AI response
Restore .ai-badge as a text pill and scope the compact icon circle to .ai-badge-ic (used by journal); worker page text badges now render at correct size
- Replace emoji icons with Lucide across admin pages; add vendor/lucide.min.js and renderIcons() helper\n- Reorder sidebar logically (Dashboard, Journal, Students, Groups, Files, Links, Trash + admin sections)\n- Groups: open photo chronology only via the Фото button; covers no longer clickable\n- Journal: show group badge over card photo, compact AI-status icon beside description, and date range in empty-state message\n- Update README (AI worker, Lucide, worker.js)
