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'.
Replaces the Stone theme with Wild Dragon branding (canvas #0A0A0A, accent cyan #97EDF0, secondary #9AE0FD, coral alert #FB819C — sourced from wilddragon.net) and reorganizes MainWindow into a Microsoft Teams-style three-column layout: a 72px left rail (logo + Participants/Settings nav + engine-status indicator), a center content area (header + participants card), and a right settings panel.
Adds InitialsConverter so participant avatars render real initials (Brendon Power -> 'BP', '(Local)' -> 'L') instead of a generic glyph. Drops the obsolete StoneTheme.xaml; the project now ships exactly one theme dictionary.
Typography: Inter (with Segoe UI Variable Display fallback) for the sans stack, JetBrains Mono (Cascadia Mono fallback) for machine names and timecodes — matching the wilddragon.net site.
Verified live against the running Teams meeting: app launches, participant 'Brendon Power' displays with avatar, settings panel surfaces NDI groups + Hide-Local toggle, engine status pill shows green/live.
