   Do **NOT** add `-p:PublishTrimmed=true`: WPF is not trim-compatible and it fails at
   runtime (BAML/XAML resource resolution), not at build time. `PublishReadyToRun` is safe.

+

+|---|---|---|

+- Renaming `<AssemblyName>` to `LlamaCasty` is the cheap win (the customer-visible exe
+  name matches what `Distribution.md` already promises; namespaces can stay `ytLive.*`).
+  It is **4 lines**, but it hard-breaks three pack URIs that spell the assembly name:
+  `MainWindow.xaml:14` (the **window icon** — taskbar/Alt-Tab), `OverlayHost.xaml:96`,
+  `RenameRecordingDialog.xaml:5`. Miss those and you ship a broken icon. Queued in TASKS.md
+  under the shipping task, not done.
+- Renaming the `%APPDATA%\ytLlive` folder is **breaking** — it would orphan every existing
+  user's layout DB, `Assets` and settings. Never do it casually; needs a migration.
+- No code compares its own assembly name (no `GetExecutingAssembly().GetName().Name` checks),
+  so the assembly name is otherwise free to change.
