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.
