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.

A point modifier typed at any point prompt pushes a frame on the session
(Session::point_mods) that asks for what it needs ("Base point:",
"<Offset>:", "First point of mid:", ".X of", "(need YZ):") and hands one
point to the command, so every command gets them from the command line
and in scripts, and they nest (FROM then M2P). `*x,y`, `*@` and `@*`
parse as world coordinates (the same as the plain forms: no UCS yet).
`<a` locks the next point to that angle from the base point: a typed
distance follows it, a pick is projected onto it, typed coordinates win.
TK is left to object snap tracking (#379).

With DIMTOL on, the DIMPOST suffix was added to the measurement only.
As in AutoCAD, the suffix (what follows `<>`, or the whole value when
there is no `<>`) now also follows each tolerance value: symmetric
(10.0mm±0.1mm) and stacked deviations alike. The prefix stays on the
measurement; limits are unchanged.

Freezing a viewport's own layer hid only its border; the model space
seen through it still showed on screen and in plots. As in AutoCAD, a
frozen viewport layer now hides the contents too, while turning the
layer off still hides only the border. The check is in the shared
layout path, so display, PDF/SVG/PNG export and plotting agree.

Center, Scale and Dynamic all zoomed to the extents, so the point or
factor typed after them ran as a command. Center now asks for the centre
point and a magnification or height (a height, nX or nXP), Scale for a
factor, and Dynamic, which needs a drag, asks for a window. A plain n
(at the first prompt and at Scale) is relative to the limits, as in
AutoCAD: 1 fits them. ZOOM All and Extents with nothing drawn used the
model limits in paper space too; Session::zoom_limits gives the sheet
there.
Builds on #372 (ZOOM inside a viewport).

`Attrib` gains optional per-attribute properties (`props`), each overriding
the attribute definition's. DXF reading takes them from the ATTRIB's groups
8/6/62/420/370; writing gives each ATTRIB the properties it is drawn with.
The renderer prefers them over the definition's. -ATTEDIT's Layer and Color
options set them; ATTSYNC resets them to the definitions, as in AutoCAD.

Typed VPLAYER ran its JSON form with no parameters and ended, so its
options ran as commands (F started FILLET). It now loops on
?/Color/Freeze/Thaw/Reset/Newfrz/Vpvisdflt until Enter, asks for layer
names (wildcards, comma lists) and then which viewports to change:
All/Select/Current/Except current (Current by default inside a viewport,
Select by point on the sheet in paper space). Changes go through
viewport.set, layer.new and layer.set; the session is one undo step.
The Model tab refuses it.

Typed LAYOUT ran its JSON default and ended, so the option and the
layout names typed after it ran as commands. It now asks for an option
(Copy/Delete/New/Template/Rename/SAveas/Set/?, Enter = Set) and the
layout name(s) the option needs, with the current layout as the default.
The options run the layout.* command bodies, so a refused name re-prompts
and the command is one undo step. Template and SAveas report that they
are not available yet and end.

In MSPACE, Extents/All/Window/Object fitted the drawing window's aspect and
paper-view height, In/Out/nX zoomed about the screen centre, and nXP was read
as nX. Now ZOOM works on the active (unlocked) viewport's model view: fits use
the viewport's aspect, zooms keep its centre, and nXP sets the viewport scale
to n paper units per model unit. Locked viewports and the Model tab are
unchanged.

When Enter was refused (Enter repeats a command that isn't available),
headless failed the cmdline.key call while the app dropped the error,
and pressing Enter in the app's command line echoes it. Both now echo
the error to the history and reply with the command-line state, the
`output` lines the key added and `error` only when Enter was refused,
the shape #351 gives cmdline.input.

The next MLEADER started again with "arrowhead first", Maxpoints 2 and
a landing line. As in AutoCAD, the order (arrowhead, landing or content
first) and the Options values (Maxpoints, leader landing, content type,
first and second angle) are now kept in Session::last_used for the
rest of the session and are where the next MLEADER starts. JSON calls
keep their documented defaults.

EXPLODE and the DXF *D block took the text height from the bare style's
DIMTXT × DIMSCALE, ignoring the dimension's overrides (SETVAR DIM*, DIMOVERRIDE),
a fixed-height text style and the DIMSCALE 0 fallback (text ~1e-10 high), and
EXPLODE always wrote rotation 0, so aligned text turned horizontal. Both now
use the geometry the renderer draws (dimension_in): its text height, angle and
the overridden text style; EXPLODE adds no MTEXT for suppressed text.

Typed at the command line or run from a script, DIMTEDIT ran the JSON
form at once and failed with "select dimensions". It now asks "Select
dimension", then "Specify new location for dimension text or
[Left/Right/Center/Home/Angle]": a point moves the text there (the text
follows the cursor in the preview), Left/Right/Center justify it,
Home restores the default position and Angle asks for the text angle.
A single preselected dimension is taken at once. Each answer runs the
existing JSON form on the picked dimension. DIMTED is its alias.

Only the direction of the picked dimension line location was used, so
the text always went outside beyond the arrowhead. A location inside
the circle (typed, picked or JSON `at`) now places the text there: the
dimension stores it as its text position, and the dimension line runs
from the text out to the arrowhead; a diameter's spans the circle,
broken around the text. DIMTIH (not DIMTOH) decides whether inside
text is horizontal. Outside locations keep the default placement.

Tolerances and alternate units copied the primary number format, so they were
rounded by DIMRND and took DIMZIN's zero suppression: DIMRND 0.5 turned a
±0.1 tolerance into ±0.0000, and 10.3 in showed as [261.50] mm. Tolerances are
no longer rounded and use DIMTZIN. Alternate units use the new DIMALTRND
(rounding), DIMALTU (unit format) and DIMALTZ (zero suppression). The new
variables can be set with SETVAR, DIMSTYLE and overrides. A DXF keeps them as
DIMSTYLE group codes 148, 273, 284 and 285.
DIMPOST is a prefix/suffix for linear dimensions, so angular dimensions no
longer get it ("90°mm"). A text override still wraps the angle.
