- Snapshot entity + SnapshotId/Source/Kind in Core - ISnapshotRepository + SqliteSnapshotRepository (Dapper, UTC ISO-8601) - migration 009_snapshots with (CameraId, TakenAt) index - DI registration in SharedComposition
- SnapshotService in Core picks the HD source by priority: live mainstream -> Majestic HTTP -> brief mainstream open -> SD fallback - thumbnails via SkiaThumbnailGenerator (Video); indexes each capture - ICameraCredentialsProvider seam keeps the service unit-testable - snapshot button on grid tiles + reuse in single-camera page - IconCamera/IconImage lucide glyphs
- Recordings page gains a segmented Recordings/Snapshots switch - SnapshotBrowserPageViewModel: camera + date-preset filters, sort, per-day timeline, multi-select with batch delete - gallery via WrapPanel; thumbnails decode capped at 320px - en/ru strings
- ImageViewerViewModel: prev/next over the filtered set, zoom/pan, rotate, flip, fit, 1:1, slideshow, copy, delete, properties - window on desktop (modal) / full-screen overlay on mobile - wheel + drag + pinch + arrow-key navigation - browser opens snapshots in-app; reloads on viewer deletes - en/ru strings
- SnapshotEdit/IImageEditor in Core; SkiaImageEditor composites arrows, boxes, text and crop, normalized coords - editor mode in the viewer: tool/color/thickness, undo, save copy - saves always as *_edited.jpg via SnapshotService.SaveEditAsync; original untouched; new DB row (Source=Edited) - en/ru strings
- IShareService in Core; desktop reveals in file manager - Android ACTION_SEND via FileProvider (manifest provider + file_paths) - iOS UIActivityViewController - share button in viewer + browser selection toolbar - en/ru strings; all five heads build
- SnapshotServiceTests: HD source-priority (live main > majestic > brief open > SD fallback), never SD when HD available - SqliteSnapshotRepositoryTests: CRUD + camera/date filters - SkiaImagingTests: thumbnail downscale, editor crop + annotation - ROADMAP: phase 14 done; snapshot share sheet ticked
- Video.Tests needs the Skia native; the SkiaSharp package bundles win/osx natives but Linux needs SkiaSharp.NativeAssets.Linux - the app loads Avalonia.Skia's native at runtime, so this is test-only - fixes 3 SkiaImagingTests failing on Linux CI (cannot open libSkiaSharp)

Summary
Turns ad-hoc snapshots into a managed feature: always-HD capture, a SQLite index, a browser, an in-app viewer with basic editing, and share. All five heads build (Win/Lin/Mac/Android/iOS), 0 warnings.
SnapshotService(Core) picks the HD source bypriority: running mainstream → Majestic HTTP
/image.jpg→ briefly open themainstream → SD fallback. Never persists an SD frame when an HD source exists.
Snapshot button added to grid tiles; single-camera page reuses the service.

page (keeps the mobile bottom nav at 5/5). Camera + date-preset filters, sort,
per-day timeline, multi-select with batch delete.
zoom / pan / rotate / flip / fit / 1:1 / slideshow, prev-next over the current
filter, wheel + drag + pinch + arrow-key navigation.
