- Post divider was on each PostCard's outer Pressable as borderBottom
(#222), which was barely visible on OLED black and disappeared
entirely in pressed state (the pressed bg ate the line). Moved the
seam to a dedicated PostSeparator component (1px, #2a2a2a) wired as
FlatList's ItemSeparatorComponent on both /feed (timeline / for-you
/ trending) and /feed/tag/[tag]. Also bumped inter-card vertical
padding (14-16 top / 16-20 bottom) so cards have real breathing room
even before the divider.
- FAB position was flaky: with <Stack> at the (app) level the overlay
could end up positioned against the Stack's card view instead of the
tab container, which made the button drift around and stick against
unexpected edges. Wrapped it in an absoluteFill container with
pointerEvents="box-none" — the wrapper owns positioning against the
tab screen, the button inside just declares right: 14 / bottom: N.
Bumped bottom offset to `max(insets.bottom, 8) + 70` so the FAB
always clears the 5-icon NavBar with ~14px visual gap on every
device. Shadow switched from blue-cast to standard dark for better
depth perception on dark backgrounds.
