showTileGridButton gets the full per-device treatment Split has: a header
chip in App Settings beside Split, its load and save lines, OFF by default
(and in the handheld defaults), a member of the displayKeys merge policy,
stripped from the settings PUT and never declared in the .strict()
SettingsUpdateSchema (sending it would 400 the whole save).
The setting also gates the Ctrl+Shift+G toggle (the applied default while the
owner's answer is pending; one line in tileShortcutFor to change): OFF, the
chord is inert and reaches the terminal like any unbound key; ON, it opens and
closes the grid where one can open. A grid that is open however it was opened
(Ctrl/Cmd+click, a dropped tab, "Open group as tiles") keeps all its chords,
the toggle that closes it included.

⤢ in a tile's header, or Alt+Shift+Enter (registry entry zoom-tile, applies
only while the grid is open and is swallowed before the Shift+Enter newline
gate), makes that tile fill the grid like tmux zoom. The other tiles stay
connected but hidden, so they measure nothing and send no resize; pressing it
again restores the grid and refits every tile, since the hidden ones have a
stale size. Zooming a tile that is not focused focuses it first (a human
selection).
As in tmux, moving focus to another tile restores the grid, and so does
removing the zoomed tile or adding one while a tile is zoomed by hand.
When the grid area cannot fit the tiles' minimum size, the grid zooms the
focused tile itself with a hint; that zoom follows focus and lifts once the
window fits again. A zoom the user chose is left alone.

Shortcut registry (DEFAULT_SHORTCUTS, group Tiles, all rebindable):
- Toggle Tile Grid, Ctrl+Shift+G: opens the grid this tab last left (one step
back after a selection outside it), else an open split as two tiles, else
the active session as one tile; pressed again, back to the single view of
the focused session. xterm emits nothing for a shifted Ctrl letter; the
browser's find-previous is overridden only where the grid can open.
- Focus Tile Left/Right/Up/Down, Alt+Shift+Arrows: a human selection of the
tile in that direction.
- Remove Focused Tile, unbound: the session keeps running.
tileShortcutFor() decides whether a chord applies (the toggle wherever a grid
could open, the rest only while one is open, so outside the grid
Alt+Shift+Arrows reach the terminal untouched) and is registry-aware. The
capture handler dispatches it, and the main terminal's and every tile's xterm
key handler return false for it, for every event type and before the
Shift+Enter gate, so a chord that applies never reaches a PTY.
Coexistence with the split pane: opening the grid over an open split closes
it (no wasted resize for the pane about to park) and seeds the grid with both
of its sessions, Pane A focused. While the grid is open openSplitPicker and
openSplitPane refuse and the Split button reads as unavailable
(aria-disabled); closing the grid never reopens a split.
