Audio UX (UI) + bottom bar rework: two-line footer (dropped/duration under bitrate/fps), centered sound meter (blank→green→yellow→red, zone markers at 60%/80%) + MIC chip (MicVolume slider, ToggleMicMuteCommand) — the mic is the creator's only audio control, desktop/game audio is automatic (KISS rule); scenes list is content-height (no dead space before SOURCES); top bar shows the connected YT account avatar/name via SyncConnectedAccount; docs updated (65 tests passing)

|

|
||||
- `ViewModelBase.SetProperty<T>()` for property change notifications
|
||||
- `RelayCommand` for all button actions; commands gate on state (e.g. Start only when Offline). **Typed `CommandParameter`s — no stringly-typed command tokens:** menu items that pick a source type pass the enum value itself (`CommandParameter="{x:Static models:SourceType.DisplayCapture}"`), so a typo breaks the build instead of silently adding an Image; `AddSource` still falls back to `Enum.TryParse<SourceType>(..., true)` for safety. The webcam item is its own `AddWebcamCommand` (it greys out via `CanAddWebcamToActiveScene` and isn't a `SourceType` — webcams are `WebcamSceneConfig`, not `Source` rows)
|
||||
- **Audio is KISS by rule** — the whole of audio is *one knob*: **desktop/game audio is automatic** (WASAPI loopback from the default output at unity, zero UI — "it just is"); the **mic is the creator's only audio control**, a single bottom-bar MIC chip: sound meter (blank → green → yellow → red with zone markers at 60%/80%, `MeterFillWidth`/`MeterBrush` from `MainViewModel.AudioLevel`) + volume slider (`MicVolume`) + mute (`MicMuteText`). No device pickers (never show device names — no "install a device you didn't know existed"), no filter stacks, no monitoring, no routing — OBS's confusion (dynamic mixer, unintuitive names, four required filters) is deliberately absent. A production-ready mic chain (high-pass → noise gate → compressor) will be applied invisibly in the mixer, unconfigurable. Capture runs only while live (privacy indicator stays off otherwise). Capture pipeline = `IAudioSource` seam + NAudio `WasapiCapture`/`WasapiLoopbackCapture` + `AudioMixer` (pending — the UI is in place now). The connected account's avatar/name shows in the top bar next to Start Stream (`AccountAvatarUrl`/`AccountDisplayName` via `SyncConnectedAccount`), so the creator always sees WHICH account will go live.

- ViewModels are constructed in XAML (`<vm:MainViewModel/>` as DataContext)
|
||||
- Services are currently instantiated in MainViewModel's constructor — no DI container yet
|
||||
- Layout persists to SQLite (`Microsoft.Data.Sqlite`); scenes/sources/asset bytes stored in the DB, asset identity is a SHA-256 content hash (1:M reuse, no file paths — assets are always available)
