Replace hardcoded gamma/saturation/brightness fields with a flexible
filter pipeline architecture. Templates now contain an ordered list of
filter instances, each with its own options schema. Filters operate on
full images before border extraction.
- Add filter framework: base class, registry, image pool, filter instance
- Implement 6 built-in filters: brightness, saturation, gamma, downscaler, pixelate, auto crop
- Move smoothing from PP templates to device stream settings (temporal, not spatial)
- Add GET /api/v1/filters endpoint for available filter types
- Dynamic filter UI in template modal with add/remove/reorder/collapse
- Replace camera icon with display icon for screen capture streams
- Legacy migration: existing templates auto-convert flat fields to filter list

Introduce Picture Stream abstraction that separates the capture pipeline into
composable layers: raw streams (display + capture engine + FPS) and processed
streams (source stream + postprocessing template). Devices reference a picture
stream instead of managing individual capture settings.
- Add PictureStream and PostprocessingTemplate data models and stores
- Add CRUD API endpoints for picture streams and postprocessing templates
- Add stream chain resolution in ProcessorManager for start_processing
- Add picture stream test endpoint with postprocessing preview support
- Add Stream Settings modal with border_width and interpolation_mode controls
- Add stream test modal with capture preview and performance metrics
- Add full frontend: Picture Streams tab, Processing Templates tab, stream
selector on device cards, test buttons on stream cards
- Add localization keys for all new features (en, ru)
- Migrate existing devices to picture streams on startup

DXcam engine overhaul:
- Remove all user-facing config (device_idx, output_idx, output_color)
since these are auto-resolved or hardcoded to RGB
- Use one-shot grab() mode with retry for reliability
- Lazily create camera per display via _ensure_camera()
- Clear dxcam global factory cache to prevent stale DXGI state
UI improvements:
- Replace "Loading..." text with CSS spinner animations
- Fix template card header gap on default cards (scope padding-right
to cards with remove button only via :has selector)
- Add auto-restart server rule to CLAUDE.md
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Generate default templates (MSS, DXcam, WGC) in memory from EngineRegistry at startup
- Only persist user-created templates to JSON, skip defaults on load/save
- Add capture_template_id to Device model and DeviceCreate schema
- Remember last used template in localStorage, use it for new devices with fallback
- Split Device Settings dialog into General Settings and Capture Settings
- Add capture settings button (🎬) to device card
- Separate default and custom templates with visual separator in Templates tab
- Add capture engine integration to ProcessorManager
- Add CLAUDE.md with git commit/push policy and server restart instructions
- Add en/ru localization for all new UI elements

- MSS and DXcam now auto-initialize on first capture_display() call, matching WGC behavior
- Remove engine.initialize() call from test endpoint to prevent WGC from initializing monitor 0 unnecessarily
- This fixes the issue where testing WGC with secondary monitor would show borders on both displays
Previously, calling engine.initialize() would initialize WGC's monitor 0 by default, then capture_display() would initialize the requested monitor, causing both to be active. Now all engines consistently auto-initialize only when needed.

- Refactored WGC engine to maintain separate capture instances per monitor
- Each monitor gets dedicated instance, control, frame storage, and events
- Supports simultaneous capture from multiple monitors using same template
- Fixed template test endpoint to avoid redundant monitor 0 initialization
- Removed monitor_index from WGC template configuration (monitor-agnostic)
This enables using the same WGC template for multiple devices capturing
from different monitors without conflicts or unexpected borders.

The critical bug was not capturing the return value from start_free_threaded(),
which returns a CaptureControl object with the proper wait() method.
Changes:
- Store CaptureControl from start_free_threaded() return value
- Use CaptureControl.wait() to block until thread finishes (not timeout)
- Remove redundant capture_control storage from frame callback
- Cleanup now properly releases GPU resources and yellow border
Tested: Yellow border now disappears immediately after capture test ends.

- Add WGC engine with aggressive COM object cleanup (multiple GC passes)
- Persist capture test duration to localStorage
- Show only short error messages in snackbar (details in console)
Note: WGC cleanup still has issues with yellow border persistence - needs further investigation

Allow LEDs to cover only a fraction of each screen edge via draggable
span bars in the calibration UI. Per-edge start/end (0.0-1.0) values
control which portion of the screen border is sampled for LED colors.

- Show RGBW/RGB channel indicator with colored squares on device card
- Move version, display index, LED count to subtitle row under device name
- Add remove button as × icon in top-right corner of card
- Hide latency from card display (still visible in health dot tooltip)
- Fix display layout overflow on narrow viewports
- Add wled_rgbw and wled_led_type to ProcessingState API schema

- Replace segment-based calibration with core parameters (leds_top/right/bottom/left);
segments are now derived at runtime via lookup tables
- Fix clockwise/counterclockwise edge traversal order for all 8 start_position/layout
combinations (e.g. bottom_left+clockwise now correctly goes up-left first)
- Add pixel layout preview overlay with color-coded edges, LED index labels,
direction arrows, and start position marker
- Move "Add New Device" form into a modal dialog triggered by "+" button

asyncio.to_thread() to prevent event loop starvation
- Turn on WLED device and enable live mode when starting DDP streaming
- Add LED strip offset field to calibration (rotates color array to match
physical LED position vs start corner)
- Add server management scripts (start, stop, restart, background start)
- Fix WebUI auth error handling and auto-refresh loop

Server fixes:
- Fix numpy uint8 JSON serialization by converting to Python int
- Change WLED payload to flat array format [r,g,b,r,g,b,...]
- Add payload debugging logs (size, LED count, sample data)
Web UI improvements:
- Add comprehensive console logging for device errors
- Log actual error messages from state.errors array
- Log device operations (start/stop/add) with details
- Fix password field form validation warning
The HTTP API may have payload size limitations for large LED counts.
Consider UDP protocols (DDP/E1.31) for better real-time performance.

- Added get_monitor_refresh_rates() function in monitor_names.py using Windows ctypes/DEVMODE to detect monitor refresh rates
- Updated DisplayInfo dataclass and Pydantic schema to include refresh_rate field (in Hz)
- Modified get_available_displays() to detect and include refresh rates (defaults to 60Hz on non-Windows or if detection fails)
- Added refresh rate display in Web UI between Resolution and Position
- Added translations for refresh rate label (displays.refresh_rate) in English and Russian locales
- Cross-platform compatible: gracefully falls back to 60Hz default on non-Windows systems
