- Add numpy-based DDP pixel packing (send_pixels_numpy) and fast send
path (send_pixels_fast) eliminating per-pixel Python loops
- Move ProcessedLiveStream filter processing to background thread so
get_latest_frame() returns pre-computed cached result instantly
- Vectorize map_border_to_leds for average interpolation using cumulative
sums instead of 934 individual np.mean calls (~16ms -> <1ms)
- Batch all CPU work into single asyncio.to_thread call per frame
- Fix FPS calculation to measure frame-to-frame interval (was measuring
processing time only, reporting inflated values)
- Add Potential FPS metric showing theoretical max without throttling
- Add FPS label to WLED target card properties
- Add fps_potential field to TargetProcessingState API schema

- Add POST /api/v1/picture-targets/{target_id}/test endpoint for single-frame
color extraction preview on Key Colors targets
- Add test button on KC target cards that opens lightbox with spinner,
displays captured frame with rectangle overlays and color swatches
- Add API docs link in WebUI header
- Swap confirm dialog button colors (No=red, Yes=neutral)
- Remove type badges from WLED and KC target cards

Introduce Pattern Template entity as a reusable rectangle layout that
Key Colors targets reference via pattern_template_id. This replaces
inline rectangle storage with a shared template system.
Backend:
- New PatternTemplate data model, store (JSON persistence), CRUD API
- KC targets now reference pattern_template_id instead of inline rectangles
- ProcessorManager resolves pattern template at KC processing start
- Picture source test endpoint supports capture_duration=0 for single frame
- Delete protection: 409 when template is referenced by a KC target
Frontend:
- Pattern Templates section in Key Colors sub-tab with card UI
- Visual canvas editor with drag-to-move, 8-point resize handles
- Background capture from any picture source for visual alignment
- Precise coordinate list synced bidirectionally with canvas
- Resizable editor container, viewport-constrained modal
- KC target editor uses pattern template dropdown instead of inline rects
- Localization (en/ru) for all new UI elements

Introduce a new "key_colors" target type alongside WLED targets, enabling
real-time color extraction from configurable screen rectangles with
average/median/dominant modes, temporal smoothing, and WebSocket streaming.
- Split WledPictureTarget into its own module, add KeyColorsPictureTarget
- Add KC target lifecycle to ProcessorManager (register, start/stop, processing loop)
- Extend API routes and schemas for KC targets (CRUD, settings, state, metrics, colors)
- Add WebSocket endpoint for real-time color updates with auth
- Add KC sub-tab in Targets UI with editor modal and live color swatches
- Add EN and RU translations for all key colors strings

Add PictureTarget entity that bridges PictureSource to output device,
separating processing settings from device connection/calibration state.
This enables future target types (Art-Net, E1.31) and cleanly decouples
"what to stream" from "where to stream."
- Add PictureTarget/WledPictureTarget dataclasses and storage
- Split ProcessorManager into DeviceState (health) + TargetState (processing)
- Add /api/v1/picture-targets endpoints (CRUD, start/stop, settings, metrics)
- Simplify device API (remove processing/settings/metrics endpoints)
- Auto-migrate existing device settings to picture targets on first startup
- Add Targets tab to WebUI with target cards and editor modal
- Add en/ru locale keys for targets UI
