Two related deliverables addressing the user's morning asks.
1. Branding: Dragon WHITE.png and Wild Dragon Logo WHITE.png from the brand kit are copied into src/TeamsISO.App/Assets/ and registered as <Resource> items in the .csproj. The rail's placeholder 'W' glyph is replaced by the real dragon mark (40x40, HighQuality bitmap scaling) with a 'Wild Dragon' caption underneath.
2. NDI Access Manager automation: NdiAccessManagerConfig service reads/writes %APPDATA%\\NDI\\ndi-config.v1.json, working in JsonNode trees so we don't clobber unrelated keys. ApplyTranscoderTopology() sets groups.send=[teamsiso-input] and groups.recv=[public, teamsiso-input] so all local senders (Teams + anything else) broadcast on the private group while local receivers can still see public sources too. Engine-side, the user's per-pipeline OutputGroups override pushes TeamsISO outputs back onto Public so downstream switchers see clean ISOs.
Atomic write: temp + replace, with timestamped backup of the prior config. ReadCurrentGroups() can be used by future UI to show what's currently configured. RestoreDefaults() reverts.
Settings panel grows an 'Apply transcoder topology' button under the NDI Network section. Click writes the system config, sets the engine's discovery=teamsiso-input / output=public, refreshes the bound text boxes, and pops a dialog with a 'restart Teams' reminder + the backup path.
- 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).
