Owner decision 8 ("when I hit the tiles button, open the tiles already!").
A click with the grid closed now opens it straight away, and Ctrl+Shift+G
runs the same function (toggleTileGrid), so the two cannot drift. What
opens comes from one pure helper, tileGridOpenSet (constants.js):
a. the grid this tab last had, if any of its sessions survive, opened
exactly (an open split closes and its sessions do not join);
b. else an open split's two sessions, Pane A focused;
c. else the open sessions in tab order (the picker's list: no detached
ones), up to what the grid takes here (the cap of 6, fewer when the
window fits fewer), the active session always among them and focused.
A click with the grid open still closes it.
The picker moved to right-click (oncontextmenu, browser menu suppressed).
With the grid open it is preselected with the current tiles, and Open
replaces them. Ctrl/Cmd+click on a tab with the grid closed opens the
toggle's set plus that session. The button's title, the Help modal and
the wiki say right-click chooses which sessions.
Docs: decision 8 and an as-built entry in the spec (Entry points too),
CLAUDE.md, the invariants (#tile-grid, Opening), the wiki's Tile Grid and
Keyboard Shortcuts pages.

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.
