Replace single preview PlateView with two stacked previews showing
horizontal and vertical FillLinear results. Each has a label showing
the part count. Apply uses the direction with more parts.

Add Vector-based overloads to SpatialQuery (ray casting, edge distance,
directional gap, perpendicular overlap) and PartGeometry (directional
line filtering) to support pushing parts along any angle, not just
cardinal directions.
Add Compactor.PushBoundingBox for fast coarse positioning using only
bounding box gaps. ActionClone shift+click now uses a two-phase strategy:
BB push first to skip past irregular geometry snags, then geometry push
to settle against actual contours.

Add FileExtension and FileFilter constants to NestFormat and update all
references across Console, MCP, Training, and WinForms projects.

The Size fix (d4222db) changed Size.Width to Y axis and Size.Length to
X axis but only updated DrawPlate/LayoutViewGL. BoundingBox, WorkArea,
rotations, DXF export, and engine code still used the old Width=X
convention, causing the fill engine to get a swapped work area (60x120
instead of 120x60) and parts to fill in the wrong direction.

Size.Parse and ToString now use WxL format (width first) matching the
natural convention. Fixed the Plate(w,l) constructor which was swapping
args when creating Size. Fixed PlateView.DrawPlate and DrawControl
ZoomToArea which had width/length mapped to the wrong screen axes.
Simplified Console --size parsing to use Size.TryParse instead of manual
split with confusing PlateHeight/PlateWidth fields. Added Command-Line
Interface section to README documenting all console options.

Relocated add and remove plate buttons from the Plates tab toolstrip
to the right side of the plate header, keeping plate actions together.

Plate nav buttons (first/prev/next/last) now sit in a centered header
bar above the PlateView with a plate info label on the left, making
navigation more accessible without reaching up to the main toolbar.

Adds a toolbar button that opens a dockable remnant viewer showing
tiered remnants (priority, size, area, location) with color-coded
overlay rendering on the plate view.

Compute the label point from the base drawing's unrotated program
and rotate the cached point instead of recomputing on each rotation.
Prevents label jitter caused by arc discretization differences.

Replace PathPoints[0] label positioning with polylabel algorithm
to place part ID labels at the visual center of each part. Labels
are now centered and readable even in dense nests.

Parts created by fill operations share a Program instance via
CloneAtOffset. RotateSelectedParts called Part.Rotate on each,
compounding Program.Rotate on the shared object (1x, 2x, 3x…)
and producing inconsistent bounding boxes. Fix tracks rotated
programs with a HashSet, rotates locations around the group center,
and anchors the bounding box corner to prevent drift.

Replace the single-pass guillotine split approach with RemnantFinder-based
iteration. After each fill, re-discover all free rectangles and try all
remaining items again until no more progress is made. This fills gaps that
were previously left empty after the initial strip + remainder layout.
Also change ActiveWorkArea border color from orange to red.

The sequencer returns parts ordered from exit point inward. Reverse
so part 1 is nearest the origin and cutting works outward.

Advanced sequencer with default 0.25 MinDistanceBetweenRowsColumns
puts every part in its own row, degenerating to a Y-sort. Switch to
LeastCode (nearest-neighbor + 2-opt) for visible results.
Also replace AddRange(linq) with foreach+Add to avoid ObservableList
AddRange re-enumerating a deferred LINQ query for event firing.

The auto-nest code paths (MainForm, MCP, Console) now call
engine.Nest(items, progress, token) instead of manually orchestrating
sequential fill+pack. The default implementation in NestEngineBase
does sequential FillExact+PackArea. StripNestEngine overrides with
its strip strategy. This makes the engine dropdown actually work.
Also consolidates ComputeRemainderWithin into NestEngineBase,
removing duplicates from MainForm and StripNestEngine.

When Strip is selected in the engine dropdown, RunAutoNest_Click
calls StripNestEngine.Nest() instead of sequential FillExact+Pack.

Moving BasePart locations via Compactor.Push bypassed LayoutPart.Offset
which sets IsDirty. Without it, graphics paths were stale until a zoom
triggered a full rebuild.

PushSelected now calls Compactor.Push instead of duplicating the push
logic. Compactor.Push moves parts as a group (single min distance) to
preserve grid layouts. Compact tries both left-first and down-first
orderings, iterating up to 20 times until movement drops below
threshold, and keeps whichever ordering traveled further.
Also includes a cancellation check in FillWithProgress to avoid
accepting parts after the user stops a nest.

ComputeRemainderStrip used the bounding box of ALL plate parts against
the full plate, missing large interior gaps between drawing groups.
Now computes remainder within the current work area based on only the
parts that were just placed. This lets subsequent drawings fill the
gap between previous drawing groups instead of being forced into a
tiny strip at the plate edge.

Show width x length and total part area on the "Nested:" row

Extract direction helpers to Helper class (EdgeDistance, DirectionalGap,
DirectionToOffset, IsHorizontalDirection) and use them to skip parts not
ahead in the push direction or further than the current best distance.
Defer line computation until parts survive bounding box checks.

The BestFitFilter's aspect ratio cap of 5.0 was rejecting valid pair
candidates needed for narrow plates (e.g. 60x6.5, aspect 9.2) and
remainder strips on normal plates. Three fixes:
- BestFitFinder: derive MaxAspectRatio from the plate's own aspect
ratio so narrow plates don't reject all elongated pairs
- SelectPairCandidates: search the full unfiltered candidate list
(not just Keep=true) in strip mode, so pairs rejected by aspect
ratio for the main plate can still be used for narrow remainder
strips
- BestFitCache.Populate: skip caching empty result lists so stale
pre-computed data from nest files doesn't prevent recomputation
Also fixes console --size parsing to use LxW format matching
Size.Parse convention, and includes prior engine refactoring
(sequential fill loops, parallel FillPattern, pre-sorted edge
arrays in RotationSlideStrategy).

Move NFP-based AutoNest logic (polygon extraction, rotation computation,
simulated annealing) into dedicated AutoNester class. Consolidate duplicate
FillWithPairs overloads, extract BuildCandidateAngles and BuildProgressSummary,
reorganize NestEngine into logical sections. Update callers in Console,
MCP tools, and MainForm to use AutoNester.Nest.

Don't overwrite the Detail label with phase-level reports — let the
per-angle and per-candidate descriptions from the parallel loops remain
visible. Only clear the label on completion.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
ReportProgress was not setting Description, so the Detail row always
showed the default em-dash. Now each phase report includes a meaningful
description, and UpdateProgress always updates the label (resetting to
em-dash when null).

PageDown keyboard navigation.

Thread ISlideComputer through BestFitCache → BestFitFinder →
RotationSlideStrategy. RotationSlideStrategy now collects all offsets
across 4 push directions and dispatches them in a single batch (GPU or
CPU fallback). Also improves rotation angle extraction: uses raw geometry
(line endpoints + arc cardinal extremes) instead of tessellation to avoid
flooding the hull with near-duplicate edge angles, and adds a 5-degree
deduplication threshold.

Brings in the full NFP implementation: ConvexDecomposition, NoFitPolygon,
InnerFitPolygon, NfpCache, BottomLeftFill, SimulatedAnnealing optimizer,
and INestOptimizer interface. Resolves conflicts by keeping master's
progress reporting infrastructure alongside the new AutoNest methods,
and adapting RunAutoNest_Click to use NFP AutoNest with async/cancellation.

Cache offset polygon geometry on LayoutPart so DrawOffset no longer
recomputes the expensive offset pipeline every paint cycle. The costly
OffsetEntity/ToPolygonWithTolerance/RemoveSelfIntersections chain now
runs only when rotation, spacing, or tolerance actually changes.
Also update temporary parts in UpdateMatrix() so preview parts during
nesting scale correctly with zoom.

Avoids visual confusion with reserved UI colors (orange preview parts,
green/blue selection windows) by using a fixed 12-color palette that
skips those hue zones. Removes unused HSLColor and RandomColorGenerator.
