Same root cause as IsChatBox — SourceType binding fails on WebcamSceneConfig,
WPF defaults Visibility to Visible without calling the converter.
Added virtual bool IsCountdown on SceneElement, override in Source.
Swapped binding to BoolToVis. Removed dead SourceTypeToVisibility converters.
SceneElement was missing virtual IsChatBox property (unlike IsWebcam, IsWebSource, IsImageSource).
WPF binding failed silently when SelectedElement was a webcam, defaulting StackPanel to Visible.
Added virtual bool IsChatBox => false on SceneElement, made Source.IsChatBox override it.
- Source.ShowDesktop bool persisted in DB (schema migration + LayoutStore)
- ClearBackdropCaptureAsync clears CaptureKey + VideoImageSource for static fallback
- Top bar: red/green/pulsing status light, avatar via BitmapImage, Log In button
- ShowStartStream now requires IsConnected
- RunMockChatPreviewAsync: simple async loop, ChatPreviewEnabled property on Source
- EnsureDefaultBackdrop called on every scene switch, seeds all 5 scenes
- SeedEndingBackdrop replaces existing, SeedChatBackdrop added
- SceneCatalog: Chat scene display name corrected (layer = 'YouTube Chat')
- Left panel spacing consistency, context menu reordered
- Border animation rendering via code-behind Storyboard approach
- 3 new backdrop assets (ending-backdrop.jpg, chat-backdrop.jpg, live-backdrop.jpg)
- Build 0 warnings, 178 tests passing
SeedBrbBackdrop() now updates the AssetId on an existing Background
source instead of bailing when one already exists. This ensures the
new brb-backdrop.jpg replaces any old image already in the DB.
SeedStartingBackdrop() moved outside the Scenes.Count==0 guard so it
fires on every startup. Existing layouts with a Background source are
skipped (idempotent check).
- Source.IsDraggable now includes ChatBox and WebSource (was Image-only)
- ChatBox default: 400×1080, top-right corner (1520, 0) on first add
- SeedStartingBackdrop: embeds starting-backdrop.jpg as Background source
in the Starting scene on first launch (pack:// resource)
- Elements panel config UI for ChatBox source (font size slider,
font/member/super-chat/background color inputs, max messages slider,
timestamp/badge toggles)
- Schema migration: 8 new ChatBox columns on Source table (ChatFontSize,
ChatFontColor, ChatBackgroundColor, ChatMaxMessages, ChatShowTimestamps,
ChatShowBadges, ChatMemberColor, ChatSuperChatColor)
- Load/save: Source SELECT and INSERT now include all ChatBox fields
- IsElementsPanelEmpty excludes ChatBox so hint doesn't cover config
- ChatBoxRenderer.cs created: WPF FormattedText + RenderTargetBitmap
renderer for on-stream chat overlay
- Slider bindings set to TwoWay for live propagation
- Assets/llamacasty-icon.png: new brand llama figure (no text)
- Assets/llamacasty-icon.ico: converted from PNG for executable
- Assets/llamacasty-logo.jpg: full logo with text
- ytLive.csproj: updated ApplicationIcon and Resource references
- All XAML windows: updated Icon references to new file
- YouTubeStreamService: added GetBroadcastLiveChatIdAsync to fetch liveChatId from broadcast contentDetails
- YouTubeChatService.Poll(): parse snippet.type to handle textMessageEvent, superChatEvent, newSponsorEvent
- MainViewModel: wire _youtubeChat.Start(liveChatId) in PrepareAndStartLiveAsync after broadcast creation
- MainViewModel: wire _youtubeChat.Stop() in StopStream before encoder stop
- MainViewModel: wire _youtubeChat.Dispose() in Shutdown
- MainWindow.xaml: updated chat DataTemplate with member badge (⭐), Super Chat highlight (💰 + gold border), timestamps (HH:mm)
- MainWindow.xaml.cs: auto-scroll ChatListBox on new messages via CollectionChanged
- Chat lifecycle is non-fatal: failures log and the stream continues without on-panel chat
Issue 3: Desktop meter now decays 2.5x faster than it rises
(DecaySmoothing=0.5 vs Smoothing=0.2). When rms drops below current
level the higher alpha pulls the bar down quickly; when audio returns
it rises smoothly. 207 tests pass, 0 warnings.
Skip Thumb clicks (let drag work normally), set value + e.Handled on
track clicks so the RepeatButton's IncreaseLarge/DecreaseLarge can't
override the jumped-to position.

1. Error text shows in red inside the desktop audio meter bar (scrollable)
when TRAX load or playback fails — user gets feedback, not just a
silent red dot.
2. LoadTrax no longer nulls _music on error — the track path is retained
so the user sees what failed and can retry.
3. OnTraxPlaybackEnded now receives the NAudio exception and surfaces it.
4. TRAX dot is green (playing) or gray (idle/no track) — no more yellow
or red states.

Push GameAudioVolume to MMDevice.AudioEndpointVolume.MasterVolumeLevelScalar
on every change. The slider now controls what Windows sends to the
headphones, so the creator hears exactly what the stream carries (minus
mic — monitored via meters only, no feedback).

All three element sections (webcam border, countdown, web URI) now use
consistent [✕][✓] button order. Green check buttons enabled with click
handlers that save current values as snapshot baseline — revert undoes
to last accepted state, not initial selection.
Countdown section buttons were swapped (had [✓][✕], now [✕][✓]).
Webcam and web sections already had correct visual order.

The web source section's visibility was bound to SelectedElement.Type
via a converter, but WebcamSceneConfig has no Type property — the WPF
binding path didn't resolve correctly and the section leaked through.
Added IsWebSource virtual property to SceneElement (mirrors existing
IsWebcam pattern), overridden in Source to return
Type == SourceType.WebSource. Section visibility now binds directly to
SelectedElement.IsWebSource via BoolToVis.

SourceTypeToVisibilityConverter returns Collapsed when Type is null;
WebcamSceneConfig has no Type property so the binding produces null.
Issue 1c of polish batch — confirmed no fix needed.
Merged the URI TextBox and check/revert buttons into one DockPanel.
TextBox fills remaining space, buttons dock right (✓ rightmost, ✕ left).
No more line-wrapping in the web source config.

The scrollbar lives inside the ScrollViewer, not the StackPanel
(ElementsPanel). Window_PreviewMouseLeftButtonDown was checking
IsDescendantOf against ElementsPanel, so scrollbar clicks fell through
and nulled SelectedElement. Now checks ElementsScrollViewer instead.
