 - Portraits, the nav buttons, status dots, rings and the breathing circle are full circles.
+- People are real photos (`designs/Portrait.dart`), never scene art: your photo is picked in Settings or by tapping the Home avatar, shrunk to 256 px and kept on the phone; members show the `photo` the server sends. No photo means an initial on a soft neutral disc. Mock mode uses bundled Unsplash portraits (`assets/images/person_*.jpg`, see `PEOPLE-CREDITS.txt`).
 - Screen padding `20` horizontal. Card padding `16`. Section gap `28`.
 - Hairlines at `colorDivider` (black 7%), borders at `colorBorder` (black 8%).
 - One soft shadow only: `0 4 18 rgba(0,0,0,0.03)`. No coloured glows.
