Owner: an empty cell need not be the last one ("the empty tab can also
be tab nr 4 or 3"). The helpers that let the grid hold cells instead of
a packed list, with no behaviour change on their own:
- fitTileCells: the cells after a shape change. The same shape keeps
every cell, holes included; a new shape keeps each tile at its row
and column when all fit (2x2 growing to 3x2: the four tiles stay
put), else the tiles pack in reading order.
- tileInDirection takes cells: focus never lands on an empty cell.
Left and right go along the row past a hole and never leave it; up
and down take the nearest row with a tile, the same column else the
nearest (lower on a tie). For a packed list this is exactly the old
rule, short last row included.
- tileCellInDirection: the adjacent cell a Move Tile chord moves into
or swaps with.
- sanitizeTileGridState reads the stored ids as cells (null for an
empty one) and returns them as `cells` beside the packed `ids`; a
dropped id becomes a hole, never a shift. The old packed format reads
as cells with no hole.

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.
Docs: decision 7 and an as-built entry in the spec, CLAUDE.md, the
invariants, the wiki's Tile Grid and Dashboard pages.

The grid now places every tile explicitly (grid-column / grid-row, reading
order) with a 6px divider track between columns and between rows, instead of
relying on DOM order and a gap. Track sizes are fractions (grid-template fr
values) that reset to equal whenever the column or row count changes.
Dragging a divider trades size between the two tracks either side, each kept
at the minimum tile size (the pure dragTrackFractions in constants.js, always
computed from the fractions the drag started with, so it cannot drift). The
affected tiles reflow locally at most once per animation frame, with no PTY
resize; each hears exactly one fit (one PTY resize) at pointer-up, and tiles
in other tracks hear nothing. Pointer capture keeps the drag on the divider,
the body locks the resize cursor and text selection for its duration, and
closing the grid or removing a tile mid-drag tears it down, as the split's
divider does. A zoomed grid shows no dividers.

window.CodemanTileGrid (constants.js), the grid's pure half:
- computeTileLayout: columns x rows by tile count (1x1, 2x1, 3x1 on a grid
area at least 1800px wide else 2x2, 2x2, 3x2, 3x3), capped at 9, and
whether every cell clears the minimum tile size (480x240).
- tileGridCapacity: how many tiles a grid area can hold.
- sanitizeTileGridState: a stored grid (ids only) made safe to apply;
unknown, deleted, detached and duplicate ids are dropped, focus and zoom
must name a kept tile, track fractions must be sane.
- tileNeighbor / tileInDirection / cycleTile: which tile takes focus when one
leaves, on a directional chord, and on Ctrl+Tab or Alt+[ ].
- TILE_SCROLLBACK (10,000 lines, not the primary pane's 50,000) and the tile
font default.
