Backend:
- VideoCaptureSource dataclass with url, loop, playback_speed, start/end_time,
resolution_limit, clock_id, target_fps fields
- VideoCaptureStream: OpenCV decode thread with frame-accurate sync clock seeking,
loop, trim range, resolution downscale at decode time
- YouTube URL resolution via yt-dlp (auto-detects youtube.com, youtu.be, shorts)
- Thumbnail extraction from first frame (GET /picture-sources/{id}/thumbnail)
- Video test WS preview: streams JPEG frames with elapsed/frame_count metadata
- Run video_stream.start() in executor to avoid blocking event loop during
yt-dlp resolution
- Full CRUD via existing picture source API (stream_type: "video")
- Wired into LiveStreamManager for target streaming
Frontend:
- Video icon (film) in picture source type map and graph node subtypes
- Video tree nav node in Sources tab with CardSection
- Video fields in stream add/edit modal: URL, loop toggle, playback speed slider,
target FPS, start/end trim times, resolution limit
- Video card rendering with URL, FPS, loop, speed badges
- Clone data support for video sources
- i18n keys for video source in en/ru/zh

- Add Color Strip Processing Template (CSPT) entity: reusable filter chains
for 1D LED strip postprocessing (backend, storage, API, frontend CRUD)
- Add "processed" color strip source type that wraps another CSS source and
applies a CSPT filter chain (dataclass, stream, schema, modal, cards)
- Add Reverse filter for strip LED order reversal
- Add CSPT and processed CSS nodes/edges to visual graph editor
- Add CSPT test preview WS endpoint with input source selection
- Add device settings CSPT template selector (add + edit modals with hints)
- Use icon grids for palette quantization preset selector in filter lists
- Use EntitySelect for template references and test modal source selectors
- Fix filters.css_filter_template.desc missing localization
- Fix icon grid cell height inequality (grid-auto-rows: 1fr)
- Rename "Processed" subtab to "Processing Templates"
- Localize all new strings (en/ru/zh)

- WebSocket test: move w,h capture to after PP filter application
so downscaler effect is reflected in reported resolution
- HTTP test: read actual thumbnail dimensions from filtered image
instead of using pre-computed values

Stability: Add outer try/except/finally with _running=False cleanup to all 6
processing loop methods (live, color_strip, effect, audio, composite, mapped).
Add exponential backoff on consecutive capture errors in live_stream. Move
audio stream.stop() outside lock scope.
Performance: Replace per-pixel Python loop with np.array().tobytes() in
ddp_client. Vectorize pixelate filter with cv2.resize down+up. Vectorize
gradient rendering with np.searchsorted.
Frontend: Add lockBody/unlockBody re-entrancy counter. Add {once:true} to
fetchWithAuth abort listener. Null ws.onclose before ws.close() in LED preview.
Backend: Remove auth token prefix from log messages. Add atomic_write_json
helper (tempfile + os.replace) and update all 10 stores. Add name uniqueness
checks to all update methods. Fix DELETE status codes to 204 in audio_sources
and value_sources. Fix get_source() silent bug in color_strip_sources.

Replace blocking REST-based capture tests with WebSocket endpoints that
stream intermediate frame thumbnails at ~100ms intervals, giving real-time
visual feedback during capture. Preview resolution adapts dynamically to
the client viewport size and device pixel ratio.
- New shared helper (_test_helpers.py) with engine_factory pattern to
avoid MSS thread-affinity issues
- WS endpoints for stream, capture template, and PP template tests
- Enhanced overlay spinner with live preview image and stats
- Frontend _runTestViaWS shared helper replaces three REST test runners
