Fixes from user testing on a real device:
- Feed: replaced an invisible spacing-only separator with an actual
hairline divider between posts.
- Android launcher icon showed Expo's default placeholder (a blue arrow)
because the app icon and the Android adaptive-icon layers
(foreground/background/monochrome) are two separate asset sets — only
icon.png/favicon.png had been replaced. Added scripts/derive-adaptive-
icon.js to crop the paw glyph out of icon.png (detected by its marigold
color) and generate all three adaptive-icon layers plus the splash icon;
this is an explicit placeholder per user's own call, not final art.
New: full pet profile (app/(app)/pets/[petId]/), matching web's
src/app/(app)/pets/[petId]/page.tsx:
- View: identity, species, bio/adoption story, follower/following counts
(tappable → list screens), the pet's own posts below.
- Follow/unfollow with real initial state (follows.isFollowing) and
optimistic toggle — unlike feed reactions, this endpoint actually
exists, so no need to fake an initial state.
- Edit screen (name/nickname/bio/adoption story via pets.update) for the
owner's own pets.
- Tapping a pet (feed header, Explore card, Pets-tab row) now opens this
profile instead of nowhere; the Pets tab's active-pet switch is now a
separate checkmark control instead of overloading the whole row tap.
PostCard's post-shape prop is now structural rather than tied to
feed.getFeed's output type, since posts.byPetId selects `pet` via the
narrower petIdentitySelect (no isVerified/owner) — both need to satisfy
the same component.
Verified end-to-end on-device: feed separator visible, own-pet profile
shows a working Bearbeiten button whose form is correctly prefilled (a
stray edit was made to Bianca's nickname field by mistake during testing
and was discarded via back-navigation without saving — never sent to the
server), someone else's pet profile shows a working Follow/Unfollow
toggle, followers list navigates correctly, and the home-screen launcher
icon now shows the paw instead of the default Expo icon.
