Layers and objects get a PlotStyle property (ByLayer/ByBlock/name) applied
through named tables (built-in default.stb and monochrome.stb, our own
definitions). DXF keeps the names in the ACAD_PLOTSTYLENAME dictionary of
ACDBPLACEHOLDER objects with group 390 on layers and objects; tables kept in
the drawing travel in a CADCRAFT_PLOTSTYLES XRECORD. PLOTSTYLE sets an object's
or the current (CPLOTSTYLE) style; STYLESMANAGER lists, creates, edits, deletes,
loads and saves tables in our own JSON format (docs/plot-styles.md). A Plot
Style Manager dialog edits a table's styles and the layout's table; the
Properties palette shows the current plot style and table.

GROUP makes named or unnamed (*A1, *A2…) groups from the selection, typed
("Select objects or [Name/Description]") or as JSON. UNGROUP removes a group
picked by one of its objects or by name. GROUPEDIT adds and removes objects and
renames a group; removing the last object deletes it. groups.list reports them.
After every command, members that no longer exist leave their groups and empty
groups are deleted (undo restores both). The drawing model and the ACAD_GROUP
DXF round trip already existed.

MLEADER's Options answered "not available yet" for Leader type sPline and
None and for Content type Block. Spline leaders now draw as smooth curves
through their points (DXF LEADER path type 72 = 1); None places only the
content at one picked point; Block asks for a block name and how it
attaches (Center extents or Insertion point) and inserts it at the end of
the landing. MLeader gains `spline` and `block` (serde defaults); DXF stays
LEADER + MTEXT/INSERT. PURGE, RENAME, copy/paste, FLATTEN, grips and
extents follow the block content. The choices are remembered like the
other MLEADER options. docs/gaps.md: top-10 row 5, F1 and F10 narrowed.

SPLINE's Knots, Object, start/end Tangency and toLerance options printed
"not available yet". Fit-point splines now take a knot parametrisation
(chord, square root, uniform), end tangents (clamped cubic with derivative
constraints) and a fit tolerance (least-squares approximation with the
fewest control points that stay within it). The spline keeps these options
so grip and SPLINEDIT edits refit the same way; DXF writes the tolerance
(44) and tangents (12/13) and recovers the parametrisation from the knots.
Object turns 2D/3D polylines with straight segments (PEDIT Spline output)
into splines through their vertices.

The options at MTEXT's "Specify opposite corner" prompt printed "not
available yet". Each now asks its question and returns to the corner
prompt: Height (also sets TEXTSIZE), Justify (TL..BR, the insertion point
is the box's attachment point), Line spacing (At least/Exactly, then a
factor such as 1.5x or a distance), Rotation (picked, or typed through the
drawing's angle settings; the box turns with it), Style (? lists them),
Width (replaces the opposite corner) and Columns (No; Dynamic and Static
say columns are not available yet). MText stores the line spacing style
(DXF group 73) so Exactly round-trips.

A PlotStyleTable model in doc with our own built-in tables (default.ctb keeps
object properties, monochrome.ctb prints black, grayscale.ctb prints the grey of
each colour's luminance). The render builder resolves each object's style by its
index colour (true colours by the nearest index) and applies colour, screening,
linetype and lineweight. PLOT/EXPORTPDF use the page setup's table (or the
plotStyleTable option); layouts with Display plot styles (PAGESETUP
displayPlotStyles, DXF plot flag 2) show it on screen and in PNG/SVG exports.

AUDIT checks for missing layers, linetypes, styles and block definitions,
current-style variables naming missing entries, invalid geometry (NaN or
infinite numbers, zero-length lines, zero-radius circles and arcs),
block definitions that contain themselves, duplicate handles, and
references to missing objects (dimension associations, groups,
constraints, viewport layer lists). It asks "Fix any errors detected?
[Yes/No] <N>:"; the JSON form `audit {fix?}` returns a structured
report. RECOVER opens a file through the read hook and applies AUDIT's
fixes. A question prompt now shows its answers without "or".

Typed END, MID, CEN, GCEN, NOD, QUA, INT, APP, EXT, INS, PER, TAN, NEA,
PAR (any start of the word from three letters, with `_`/`'` prefixes)
and NON push a one-pick snap frame on the point-modifier layer: the
prompt reads "Endpoint of:", a typed point is snapped with that mode
alone within the aperture (or rejected with "No Endpoint found for
specified point."), and the canvas snaps the cursor with it
(Session::snap_override). A command's own keyword still wins (ARC/ZOOM
`cen`); `_cen` always snaps. Overrides nest with FROM and the filters.
Shift+right-click or Ctrl+right-click on the canvas opens the object
snap menu (From, Mid Between 2 Points, Point Filters, the snap modes,
None, Osnap Settings...), whose items type the same overrides. Tab over
a snap marker with nothing typed cycles the candidate snaps
(pointmod::snap_candidates: the running snap first, then the closest of
each mode).

PLINE arc mode answered "not available yet" for Angle, CEnter, Direction,
Radius and Second pt, and line mode for Length. Each now asks its questions
(included angles and directions read the drawing's angle settings) and adds
the segment. XLINE's options were already in draw2's XlineM2; the dead
keyword stub in draw.rs's RAY machine goes, and Offset/Reference use the
polyline segment picked rather than the first one.

Resting the cursor on a snap point acquires it for tracking (seven at
most; resting again releases it). Acquired points send horizontal and
vertical alignment paths, or every polar angle with POLARMODE 2; the
cursor snaps where two paths cross, where a path crosses an object, or
onto the nearest path. EXT runs a line or arc on from an acquired end,
PAR gives a path parallel to a rested-on line through the base point,
APP snaps where objects would meet if extended. Direct distance entry
follows the path the cursor is on. POLARMODE is now AutoCAD's bitcode;
POLARADDANG and AUTOSNAP are new.
The engine owns all of it (Session::snap_cursor, snap/tracking.rs); the
canvas draws the + markers, dotted paths and tooltip.

The options TRIM and EXTEND list at their prompt all printed "not available
yet". Quick and Standard modes follow TRIMEXTENDMODE, Edge extends lines and
arcs virtually (EDGEMODE), Project is kept in PROJMODE. The JSON forms take
fence, crossing, edgeMode and (TRIM) mode.
