The lane strip replaces the placeholder board: window width divides
across the lanes' width units (no horizontal scroll, no minimum width,
degenerate compression accepted), a lane of n units flowing its cards
into n round-robin masonry columns via a measurement-cached Layout.
Width has two deliberately opposite controls, both landing here: the
right-edge drag (ported verbatim from the pathfinder's ColumnResize)
freezes the 1x standard at drag start, snaps between integer widths
with the asymmetric shadow-leads tick and 10pt re-entry, grows the
window one standard width per snap so siblings keep their exact
pixels, and rubber-bands at the screen's visible frame — uncapped
otherwise; the Increase/Decrease Lane Width items (new Board menu,
Cmd-Opt-arrows) are the stepper's keyboard face and re-divide the
existing window width instead, never touching the window. Width
changes write through the new .resize WriteOperation ("Couldn't
resize…" in the banner vocabulary, which grows with the surfaces by
design); malformed width values render as one unit and stay untouched
on disk. 27 new tests port the pathfinder's resize-math suite onto
the uncapped range and pin the write path's fidelity.

The banner surface as one vocabulary (Kanban/LiveStore/BannerCenter,
Kanban/UI/BannerStripView): a pure precedence rule — in-progress pinned
above the collapse (ratified mid-build), lock > breakage > one-shot
write failures > commit+attachment, signposts last — with all
user-facing phrasing owned here via exhaustive switches over the closed
WriteOperation enum; free-form English survives only in diagnostics.
performWrite posts its failures before rethrowing, so no one-shot can
bypass the strip; refusals under lock post nothing.
The lock vocabulary completes: vanishedRoot and unwritableLocation join
bracketedReloadFailed, each with its own clearing rule (unwritable
clears only on a reconciling reload's writability re-probe). The
registry now owns root recovery: bookmark re-resolution absorbs renames
transparently, a dead root locks read-only and re-arms FSEvents on the
gone path so the root's return round-trips back through rootChanged,
re-minting and re-keying on the way. DirtyBufferGuard is the one modal
moment, retry / save a copy / discard, no fourth button.
36 new tests; full suite 333 tests in 62 suites green. Five findings
filed on the Redesign board.
