FNXC:Navigation 2026-06-22-01:10:
The header row now comes from the shared .view-header (which supplies the --space-lg top/side padding).

FNXC:ViewHeader 2026-06-23-03:45:
The shared ViewHeader now owns the surface background without a bottom divider, so this wrapper drops its own border-bottom/background to avoid a doubled divider under the title row. The controls row keeps its own side/bottom padding so the tab bar/search stay aligned.

FNXC:ViewHeader 2026-06-22-12:00:
Artifacts controls are the first page content below the shared header, so add a top inset there instead of on the header wrapper. This keeps the tab/search row from bumping against the title divider while preserving the existing body alignment.
