Two user-reported bugs:
1) CheckBox content was clipping in the 380px settings panel ('Control surface (Stream Deck / Companion / w...' / 'LAN-reachable (allow other machines on yo...'). The Wd.CheckBox template used a horizontal StackPanel which doesn't bound child width, so long Content strings ran off the column without wrapping. Replaced StackPanel with a Grid (Auto + *) and injected a TextBlock style with TextWrapping=Wrap into the ContentPresenter resources — when WPF auto-wraps a string Content in a TextBlock, the resource lookup gives it Wrap.
2) The rail Launch Teams button ambushed operators: clicking with Teams already running (which is common when the eye-toggle has hidden Teams' windows) opened a 'Close all Teams windows now?' dialog. Operators expect Launch to mean 'show me Teams', not 'stop Teams'. Split the actions:
- Left-click: Teams not running → launch; Teams hidden → restore + foreground; Teams visible → bring to front. Always idempotent-progressive.
- Right-click: ask to stop Teams (preserves the kill path for those who want it).
TeamsLauncher.TryLaunch now collects per-attempt errors instead of swallowing them — a real failure surfaces 'ms-teams: URI → <reason>' / 'AppsFolder shell → <reason>' / 'classic Update.exe → not found at <path>' so 'No Teams found' isn't a black box.
Also added a 2nd path: explorer.exe shell:appsFolder\\\\MSTeams_8wekyb3d8bbwe!MSTeams (AppX activation via the OS's own Start-menu verb) as a fallback if the URI handler is misconfigured. Removed the broken bare-stub call to %LOCALAPPDATA%\\\\Microsoft\\\\WindowsApps\\\\ms-teams.exe — that's a 0-byte AppX placeholder that never worked outside an AppX context.
Four polish items + a test pass.
1. Inter Variable (rsms/inter v3.19, OFL) is bundled at Assets/Fonts/Inter.ttf (~800 KB) and registered as a WPF Resource. WildDragonTheme.xaml's Wd.Font.Sans now points at pack://application:,,,/Assets/Fonts/#Inter so the typography matches wilddragon.net regardless of whether the user has Inter installed system-wide. Falls back to Segoe UI Variable Display if the resource is missing.
2. 'Stop all ISOs' button at the right of the participants header. Bound to a new MainViewModel.StopAllIsosCommand that snapshots the enabled list, awaits DisableIsoAsync sequentially, and silently swallows per-pipeline failures (best-effort emergency stop). CanExecute gates on whether any ISO is currently enabled.
3. WindowStateStore service persists the main window's Left/Top/Width/Height/State to %LOCALAPPDATA%\\TeamsISO\\window.json on close and restores it on SourceInitialized. Multi-monitor friendly: a saved position with no corner inside any virtual screen is rejected so a disconnected monitor doesn't strand the window off-screen.
4. Two new unit tests cover FrameProcessor's drops + duplicates accounting. 76/76 unit tests pass (was 74).
Six related polish items, all building on tonight's groundwork.
1. App icon: teamsiso.ico generated from dragon-mark.png at 7 sizes (16-256), wired as ApplicationIcon in the WPF csproj, MainWindow.Icon, AboutWindow.Icon, and ARPPRODUCTICON in the WiX MSI. Taskbar / window / Add-Remove-Programs all show the dragon mark now.
2. Running incoming FPS: ring buffer of last 30 frame timestamps in IsoPipeline; ComputeFps() returns moving-average rate. Surfaced on IsoHealthStats.IncomingFps and shown in the Source column of the participants DataGrid as 'WxH · 59.94 fps'. Resets cleanly on every supervisor restart.
3. Drops counter: FrameProcessor.Stats already aggregated FramesDropped (closest-frame strategy when the receiver outpaces the processor) and FramesDuplicated; just plumbed _liveProcessor through IsoPipeline so GetStats() can read them. Exposed in the Live column under the in/out counters as a coral-tinted 'drop N'.
4. Console --version flag: prints engine version (with embedded git SHA), .NET version, OS, NDI runtime banner, expected prefix, exit-code legend, plus a wilddragon.net link. Useful for support tickets.
5. About dialog: chromeless modal with the dragon mark + version / .NET / OS / NDI runtime fields and a link to wilddragon.net. Triggered by clicking the rail logo.
6. Teams launcher Stop toggle: TeamsLauncher gains IsRunning() and StopAll(). The rail's Teams button now toggles — if Teams is up, ask to close all Teams windows via WM_CLOSE; otherwise launch as before. Confirms before stopping so we don't kill the user's call mid-transition.
Tests: 74/74 unit + 9/9 NDI integration green throughout. MSI builds clean and now embeds the dragon icon for ARP.
First step of Phase E.1 from the new spec at docs/superpowers/specs/2026-05-08-embedded-teams-orchestration.md: a third icon in the left rail launches the Microsoft Teams desktop client as a subprocess of TeamsISO so the operator doesn't have to leave the app to start a meeting.
Services/TeamsLauncher tries the ms-teams: URI first, falls back to %LOCALAPPDATA%\\Microsoft\\WindowsApps\\ms-teams.exe (new Teams), then the classic Update.exe handoff. On failure surfaces a friendly MessageBox with the install link.
The spec doc lays out the full three-phase roadmap (launcher -> window orchestration -> in-app meeting controls via Graph API or UIAutomation) and explicitly calls out what's out of scope (replacing Teams' media stack).
_NEXT.md updated to mark Phase D done and queue Phase E + remaining polish items (code-signing, Inter/JetBrains Mono font bundling, real Wild Dragon dragon-mark, drops counter, running-fps display).
MainWindow drops the standard Windows title bar (WindowStyle=None + WindowChrome with CaptionHeight=44, ResizeBorderThickness=6, UseAeroCaptionButtons=False) and draws its own minimize / maximize-restore / close buttons inline in the existing header strip. The custom buttons opt into shell:WindowChrome.IsHitTestVisibleInChrome=True so clicks fire on them rather than starting a window drag.
Result: the entire top of the window is now ours, matching the Microsoft Teams desktop client's flush header look. The 'TeamsISO + by Wild Dragon' branding sits at the same baseline as the engine-status pill and the caption controls, and dragging anywhere not occupied by an interactive widget moves the window.
Caption-button styles in the theme: 46x32 hover-tinted, with the close button turning the Windows 11 #C42B1C red on hover. Maximize-button glyph swaps between the single-rectangle and overlapping-rectangles variants on StateChanged.
Drive-by: ParticipantViewModel.{FramesIn,FramesOut,IncomingResolution} setters dropped from private to public so {Run Text=...} bindings (which default to TwoWay on Run) can attach without WPF throwing 'cannot work on read-only property'.
- TeamsISO.App: hand-rolled net8.0-windows WPF csproj since the WPF
template isn't shipped on linux-arm64 .NET SDK; UI is a placeholder
for Phase C.
- TeamsISO.Engine.IntegrationTests: cross-platform xunit project with a
skipped scaffold fact tagged [Trait("requires", "ndi")] for Phase B.
- TeamsISO.Linux.slnf: solution filter for non-Windows CI that excludes
the WPF project (which can only build on Windows).
