The repo mixed variants such as center/centre and color/colour, so a
name could be spelled either way and searches missed half the hits.
Standardize on the US spelling, matching .NET's own APIs (Color, Center).
Wire values owned by other systems keep their spelling: the material
ledger's "Cancelled" hold status and GitHub's "cancelled" job status.
No behavior change beyond the spelling of a few status messages.

Plates with staged automatic scrap cut-offs could not be planned: P260810-01
plate 1 ran out of budget even at 10x effort, while the same plate plans
Ready in 3.6k expansions without the lines. A cut-off was one fixed program
cut whole before every part its line passes through, which dragged the tour
to the middle of the sheet and left the head at the far edge of the line;
and cutting every line first (the rejected alternative) weakens the sheet
and breaks the containment operators rely on when they fast-forward a
changed program.
A cut-off stays one definition, but Plate.RegenerateCutOffs now makes one
part per trimmed segment, each with its own place in the cut sequence.
CutOffSegments gives each segment the span of the nominal line it stands
for (end of the segment before it to start of the one after), and the
dependency rules of the planner and Part Sequencing use that span, so a
segment precedes only the parts beside it. The free-order search plans the
parts as if the segments were not there, so adding lines no longer changes
a plate's route, then CutOffInsertion slides each segment into the latest
gap before its first part where the rapid into its pierce and the rapid
from its end cross nothing cut before; only when one fits nowhere is the
plate searched with the segments among the parts. The search looks through
segments wherever they sit (entries face the next part, hole routes rank
from the pre-segment position, rapids are still checked from the segment's
end), so an applied plan replanned with the order kept replays Ready.
Segments saved out of consecutive order are recorded per segment in the
.nest file (`segments`); older readers load them consecutively.
P260810-01 plate 1 now plans Ready in 3639 expansions with every check
passing; rapid travel 1836 against 1547 without the lines. Plates without
cut-offs keep their PlanningCharacterizationTests digests, and the
problem-nest corpus has no plate below its baseline.

Changing a rate, the pierce time or the machine rebuilt the timeline and
kept the playhead's old time. That time pointed at a different move on
the retimed timeline, so the torch jumped around while settings were
adjusted. When the new timeline has the same moves, Load now finds the
same move and how far through it the torch was (CutSimulation.TimeAt
inverts FractionAt, acceleration included).
The in-progress rapid was drawn whole with a dashed pen. GDI+ cost grows
with dash count: zoomed in, one paint of a long rapid can take seconds
to minutes. It is now clipped to the visible area, as finished rapids
already were.

The cut simulation treated Display-layer contour moves (what cutting
strategies emit) as head-up travel, so plates with assigned lead-ins were
timed as rapids. They now cut, matching the verifier and posts, and
suppressed moves are left out.
Cut time now follows the CI Fiber post: closed clockwise contours and
cut-offs take an outside feed, other contours a hole feed, and etch-only
contours can be skipped like its SkipScribe default. The settings are
shared by Calculate Cut Time and the simulator, and plate/nest times now
always come from the simulation.

A Grbl-style lookahead planner re-times the cut simulation with
trapezoidal acceleration, junction-deviation corner speeds and a
centripetal cap on arcs. Machines gain cut/rapid acceleration and corner
deviation in Machine Configuration, with placeholder values until the
controller's are entered. The simulator and Calculate Cut Time pick the
machine (or full speed), and the simulator shows the live head speed.

Plate > Simulate Cutting replays the active plate in cutting order: the
torch traces cuts, rapids and pierces timed like Calculate Cut Time, with
play/pause, scrubbing, 1x-250x speed, step and part/cutout jumps. Parts
the torch has not reached are drawn muted.

Quality review of 50884da found the unshown RichTextBox oracle compared
cached CRLF text against the highlighted editor's native LF-normalized
text, which would fail on first Windows execution. Compare generated
text with normalized line endings on both sides instead, capture the
status label and preview state inside the ProgramChanged handler to
prove fallback-before-notify ordering, document the HighlightSpan
UTF-16 and rule-index contract, and pin the null-text argument check.
Program.Clone deep-copied the SubPrograms dictionary but left every
SubProgramCall pointing at the source's sub-program, and
SubProgramCall.Clone went through the Rotation setter, which re-rotated
that shared program to the call's stale angle. Copying a program with
hole lead-ins therefore rotated the source's holes, and rotating the
copy rotated the source again.
Program.Rotate also rotated a shared sub-program once per call, so two
identical holes (one deduplicated sub-program) turned twice.
Clone now binds calls to one private copy per shared sub-program
without re-aligning it, and Rotate turns each distinct sub-program once.
RapidEnumerator primed the walk position at the first pierce point, then
the skipped first rapid advanced it again. Raw programs start with a zero
rapid so this was invisible, but lead-in programs start with a real
incremental offset to the pierce, which shifted every later rapid by that
delta and drew rapids off the sheet. Start the walk at the program origin.

Min/max were seeded at 0, so any geometry not touching the origin got an
inflated box, and the first move only updated max (else-if). Rotated
canonical drawings are the common trigger: their origin ends up outside
the shape, which skewed Part bounds and bbox-based alignment.
Track the real extents and keep returning a zero box for empty programs.

Repo-wide sweep with the pinned CSharpier 1.3.0 tool. Whitespace and
line-wrapping only; OpenNest.Engine.Tests (109) and OpenNest.IO.Tests
pass after reformat, full solution builds 0 errors.
Added .csharpierignore so csproj/config XML keeps its existing layout
(CSharpier's XML wrapping churns attributes with zero benefit).
Formatting is now enforceable: dotnet csharpier check . passes.
Pulls the rapid-walk logic (sub-program unwrapping, first-pierce lookup,
incremental-vs-absolute handling, first-rapid skipping) out of
PlateRenderer.DrawRapids into a reusable RapidEnumerator in Core so it
can be unit-tested and reused outside the renderer.

Adds Dictionary<string,string> VariableRefs to Motion (cleared on Rotate/Offset) and string VariableRef to Feedrate, with deep-copy Clone() support, so post processors can emit variable references instead of literal coordinate values.

Adds immutable VariableDefinition record to OpenNest.CNC with name,
expression, resolved value, inline, and global flags. Fixes namespace
collision in PatternTilerTests and PolygonHelperTests caused by the new
OpenNest.Tests.CNC namespace.
