Subject: [PATCH] feat(android): adaptive launcher icon with Material You
 themed-icon support
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replace the placeholder system icon with the Punktfunk brand mark (two overlapping violet circles,
from the shared logo in clients/apple/.../punktfunk_Logo.icon).

- drawable/ic_launcher_foreground.xml: the violet logo (3 exact paths) scaled + centered into the
  108dp adaptive-icon safe zone via a group transform.
- drawable/ic_launcher_monochrome.xml: single-tone silhouette for Android 13+ themed icons
  (Material You) — the launcher recolors it to the wallpaper.
- mipmap-anydpi-v26/ic_launcher{,_round}.xml: adaptive-icon (background + foreground + monochrome);
  dark-indigo background (@color/ic_launcher_background) so the violet pops.
- Manifest: android:icon=@mipmap/ic_launcher + roundIcon (was @android:drawable/sym_def_app_icon).

minSdk 31 → anydpi-v26 covers every device (no legacy PNG mipmaps needed). Verified on a physical
phone (Android 16): the icon renders centered + circle-masked; the themed-icon layer is wired.
