SubHeaderBar switched to ArcBackground variant="rect" (commit 207794e7)
when navigation was restyled with V-angled bars, but 15 pages still
rendered a 20px ARC_OVERHANG_PX spacer div directly below the tab bar
to leave room for the now-removed downward arc. That spacer is the
empty band the user reported underneath the tabs.
Drop the spacer divs and their now-unused ARC_OVERHANG_PX imports across
Feed, Search, Notifications, Profile, Videos, Photos, Relay, Letters,
Music, ExternalContent, ArticleEditor, PeopleListDetail, BadgeDetail,
Communities, and Badges. FollowPage keeps the import because it still
renders an actual <ArcBackground variant="down" /> at the top of its
profile feed scrollbox.
Lets users post either to the global Nostr feed (kind 1) or to one of
the country communities they follow (kind 1111 rooted on the country
ISO 3166 identifier, mirroring the country page's compose flow).
Layout choices that ended up sticking after iteration:
- Dropdown lives on its own row above the toolbar so the 'Post to'
label can anchor its semantic meaning without competing with the
attach / emoji / mic / poll icons below.
- Trigger renders only the flag emoji to stay compact on mobile;
the open list shows flag + country name so options remain
distinguishable.
- A small help popover next to 'Post to' explains Global vs. country
community for users new to the concept, with the second item's
flag swapping to the currently-selected (or first followed)
country so the explanation feels tangible.
- Toggle only renders when the user is logged in, followed at least
one country, isn't replying, and isn't in poll / customPublish mode.
Resets to Global after each publish so country-mode never sticks
silently across posts.
The gradient surface, ring, shadow, and country label were doing too
much work now that the flag backdrop carries the visual weight of
'this is a country post'. Reduce the pill to just the flag emoji
inside a Link with a hover scale and the existing hover-card preview.
Cleaner read in the card header; the eye sees flag-backdrop fading
into the body of the post, then a clean flag emoji as the
right-anchored 'tap to go to country feed' affordance.
