The replica framed to a font-derived nominal width, so faces in wide
lanes' interior masonry columns and narrow lanes dragged a preview of
the wrong size and the cursor could sit over empty space beside it.
CardFaceView's existing onGeometryChange now reports size, not height
alone - height still feeds LaneDropRegistry, width feeds the replica -
and BoardMetrics.cardReplicaWidth(measured:bodyPointSize:) keeps the
old figure as the documented not-yet-laid-out fallback. Same row, same
paddings, same lineLimit at the same width means the same height, so
the preview is now an exact overlay of the face it left.
Manual verification pending alongside the lane grab-point card: 3x vs
1x lanes, interior masonry columns, window re-divide, trash rows,
large text sizes, drag-at-creation fallback.
3 tests. 1661 green on both schemes.

Full relative text scaling per DESIGN/10: BoardMetrics is the board
strip's geometry as a pure function of the body point size
(CardWindowMetrics' twin) — lane plate/header/band, card
corner/stripe/padding, masonry spacing, the drop model's nominal card
height, resize-handle geometry, trash hatch pitch, and both window
floors all derive from an em; CardFaceMetrics folded in. The two fixed
font sizes (welcome brand/glyph) went relative; the toolbar search
field is 17 ems like the transient bar's. The no-horizontal-scroll
invariant is pinned by test at six text sizes by twelve lane counts.
Accommodations is Motion's sibling for the visual settings: Increase
Contrast adds a flat point to strokes (monotone, hierarchy-preserving),
gives borderless card/lane plates a resting separator hairline, and
takes faded accents to full alpha; Reduce Transparency turns the
transient search bar's glass solid and does the same for the alpha
washes that composite over a user-chosen board background (trash plate,
hatched header, drag shadow). Reduce Motion audited — every animated
surface already routes through Motion with a reduced variant; no gaps.
Full Keyboard Access: the template chooser's tiles were pointer-only —
now focusable, arrow-navigable (clamped, StyleWellGrid's rule), Space
picks, Return stays the sheet's default action, focus names the
selection one-way. The board's single tab stop shows its focus ring
under FKA (focusEffectDisabled inverts). Style editor verified already
conformant. Edge accents verified text-free; trash hatch pitch now
font-derived so it still reads as hatching at large text.
1549 unit tests green, both schemes build.
