Six was tested smooth on the owner's desktop; nine missed the headless
frame bar and is untested on real hardware. TILE_GRID_MAX (constants.js)
is now 6 and stays the one cap every limit reads; the layout table gets
its own bound, TILE_LAYOUT_MAX = 9, so the 7 to 9 layouts keep working
(unreachable) and going back to nine is that one line.
Every way in stops at the cap: opening, addTile, a tile's +, a session
Run makes, Ctrl/Cmd+click, the picker, "Open group as tiles", and a stored
grid with more ids (it comes back as its first six, focus kept only if it
survives, a dropped zoom cleared, row fractions that no longer match the
3x2 reset). The limits now go through one helper, _tileGridLimit(), whose
texts say which limit binds: "Up to 6 tiles" / "The grid holds at most 6
tiles" when it is the cap, "This window fits N" when it is the window.

invariants, the wiki's Tile Grid and Dashboard pages.

The grid is stored in localStorage `codeman:tile-grid` as
{ v: 1, open, ids, focused, zoomed, colFr, rowFr }: ids, focus, a zoom the
user chose (an automatic one is worked out again from the window) and the
divider fractions, never content. It is written as it changes (layout, focus,
zoom, divider drags); closing the grid keeps it remembered as open: false for
one-click return, and the last tile leaving forgets it. That stored state is
now the only "remembered" grid, so the Tiles toggle, the picker's preselection
and Ctrl/Cmd+click all bring back the grid this device last had, across
reloads. Never written or read in a solo window.
The restore runs INSIDE handleInit, in place of its single-view
selectSession(restoreId, { auto: true }), so with a stored open grid the main
terminal never loads on that page load (its first select would pull a
whole-history capture only to be parked). The stored ids are sanitized against
the session list (deleted, detached and duplicate ids dropped, anything that
is not a v1 object ignored), and the fractions and zoom go back on. A window
too narrow for the grid keeps the single view and the stored grid waits; a
#session= link on load wins and leaves the grid remembered but closed.
