Every tile gets a fixed-height header above its body: `● name ......... ⋯ ×`.
- The dot is the six-state classifier the tab rows and both home screens
share (_sidebarRichRow), with the existing .home-sessions-dot--* classes;
hovering the header says the state and for how long ("working 3m"). A
tile whose session waits on a permission prompt or question gets a pulsing
red border (box-shadow only, never layout; still under reduced motion).
- The name is text with data-i18n-skip; a double-click renames it through
the tab rename's own write queue (Enter or leaving the field commits,
Escape cancels, an IME composition owns Enter), and an in-flight name shows
as already applied, as on the tab.
- ⋯ is the tab rail's session menu (options, new window, close session with
its confirm); × removes the tile ONLY, the session keeps running. Neither
button focuses a tile that is not focused.
- The header is fixed at 24px so nothing in it can resize the body, and with
it the xterm and its PTY (#464).
Every tab render refreshes the headers, so they follow status and name
changes. Tabs of tiled sessions carry .in-tiles (both render paths), and the
tab strip re-renders when tiles come and go.
