As the branch does for older tests: `panic!("…")` instead of
`unreachable!()` in test code (clippy.toml only allows unwrap, expect and
panic there), and the integration tests main added (CLI file I/O, render
gradient text and stroke geometry, SVG export suites) opt out of the
unwrap/expect/panic lints. No test logic changed.

With the Gradient tool on a freeform gradient the selected point shows its
spread as a dashed ring with a handle; dragging either sets the spread. A
point dragged out of the object is removed on release, and double-clicking a
point opens the gradientStop popover, which now edits the selected freeform
point (colour, opacity, spread). In Lines mode successive clicks draw one
smooth line (with a rubber band to the pointer); clicking an existing point
continues the line from it, and Escape or a click off the art ends it.

A CMYK document that shows transparency is drawn once per ink plane
(complemented C, M, Y; complemented K as a grey) so every blend mode,
opacity, group, knockout and effect composites inks, PDF-style; the
planes' inks are shown through the working CMYK profile (cached 4-D XYZ
table). Cyan multiplied over magenta now shows C100 M100. Opacity masks
keep screen luminance; RGB colours and placed images are separated
first. RGB documents and opaque CMYK documents keep the screen-colour
path.
PDF export of CMYK documents writes its transparency groups with
/CS /DeviceCMYK (luminosity mask groups stay RGB) and puts top-level
transparency in a non-isolated page-wide group so it blends in CMYK too.
Flatten Transparency composites CMYK documents ink by ink and makes CMYK
regions. Non-separable modes no longer give NaN for greys.

Scaling with Scale Strokes & Effects on now scales stroke weights, dash
lengths and dash offsets and every distance parameter of object, fill and
stroke effects (groups and layers too), from new length metadata in the
effects catalogue. Off, nothing painted changes size and type keeps its
character strokes' weight. Scale Corners off keeps live corner radii.
object.scale/transform/transformEach take strokes?/corners? (default: the
preferences) and journal the values they used. The Scale dialog and a new
Transform Each dialog get both checkboxes, kept as the preferences on OK;
the panels' toggles go through prefs.set.

Window > Attributes (Cmd+F11) shows Overprint Fill/Stroke, Show/Don't Show
Center, Reverse Path Direction Off/On, the non-zero / even-odd fill rule,
Image Map, a URL field with recent URLs and a Browser button, and a note.
New commands attributes.set and path.setFillRule; path.reverse takes ids and
reversed; attributes.info reports every value. Objects keep the attributes in
Node.attrs. SVG export wraps linked objects in <a>, and import reads links
back. The canvas draws the centre point of selected objects that show it.

Paint given to a clipping path (paint commands with its id) now shows: its
fill paints inside the clip behind the clipped art and its stroke over the
art, unclipped, on the canvas and in SVG and PDF. Node::clip_paint splits the
clipping path into its fills and its strokes (type: its characters' too) for
all three outputs; the renderer caches the parts per clipping path. Clip group
visual bounds take in the stroke. Make Clipping Mask still leaves the clipping
path unpainted, as the reference app does; Ungroup no longer wipes a painted
clipping path's appearance (Release already kept it).

Paths and compound paths now measure their visual bounds along their shape:
the body (inside/outside alignment, the width profile's widest point), the
tips of the miter spikes the limit keeps, projecting caps' corners and the
arrowheads' reach. A rectangle's right-angle miters stay within half the
weight (Fit to Selected Art, Rasterize and all-art SVG export get tighter,
exact boxes); Appearance::outset is the conservative reach for anything else.
Clicks hit what the strokes paint: outside strokes outside the path (0.8 x the
weight out), inside ones inside, the profile's width where clicked, caps,
spikes and heads. Click culling keeps a cheap box (hit test 0.34 ms per click
on the 50k-path budget). The subpath/tangent helpers move from the stroke
geometry into vectorcraft_geom::bez so both share them; a cross-check test
holds every painted point of the real stroke geometry inside the bounds and
hittable.

The Control bar and Properties Fill/Stroke chips show the proxies' paints
("?" for mixed selections) and open a popover with the Swatches panel body
(Shift-click or the toggle: the Color panel's mixer); a click brings the
chip's proxy forward through paint.toggleActive {fill}. The Properties
panel offers Recolor for multi-colour selections. Window panel shortcuts
(Color F6, Color Guide Shift+F3, Appearance Shift+F6, Graphic Styles
Shift+F5, Stroke Cmd+F10, Gradient Cmd+F9, Transparency Shift+Cmd+F10)
run window.panel {panel}, show in the Window menu and are editable.
paint.invert / paint.complement and the "?" state honour the Appearance
panel's active item; objects without bounds still show their paints.

Freeform gradients carry their own points (colour, opacity, spread) and lines
(Catmull-Rom curves through points), blended by inverse-distance weighting
from each disc of pure colour. paint.editGradient {kind: "freeform", mode?}
places 4+ points inside the shape, coloured along the stops (which follow the
points' colours). The renderer samples the field on a cached colour grid
drawn as an image paint clipped by the fill or stroke. Moves, transforms,
box rebases and warps move the points; old files load unchanged.

A group's or layer's own fills and strokes paint every member's geometry, below or above the
members as the new contents slot (Appearance.contents_index) says; its geometry effects reshape
the members as one piece and its raster effects apply to the composite (one combined shadow),
respecting knockout groups. Type's own fills and strokes paint under or over its characters.
Render, SVG/PDF (via bake) and Expand Appearance evaluate them alike.
Commands: appearance.* / effect.* take target: "object"|"contents" and layer ids;
appearance.moveItem moves the Contents slot (from: "contents") or an item across it
(contents); appearance.targetContents selects a group's members. Graphic styles applied to a
group now style the group itself. The Appearance panel shows Contents/Characters rows that
drag, and double-click to target the members or edit the characters' paint.

layer.clippingMask.toggle {id?} -> {clip}: the top object of the current
layer (or of the one selected group, or of `id`) becomes the clipping path,
unpainted and moved to the bottom so art added later is clipped too; pressing
the button again releases the mask and leaves the path unpainted. One undo
step. The Layers panel button runs it and underlines clipping-path names.
Model: NodeKind::Layer.clip (skipped when false). Clipped layers render, hit
test, bound, and export to SVG and PDF like clip groups (Node::clips /
set_clips); the clip-path helpers are shared with Make/Release Clipping Mask.

On screen, a group (or object) with opacity, a blend mode, an opacity mask or
knockout whose content blends is drawn offscreen over a copy of its backdrop
and mixed back in by its opacity, mask and clip (a group blend mode then
applies to the backdrop-free result, as PDF defines it). Isolate Blending keeps
the content starting from transparency. Clip groups no longer isolate their
children (blending content is clipped per drawing), and non-isolated knockout
groups composite their elements against the art below the group. Groups
without blending inside still render as plain layers.
In PDF, such groups are written as non-isolated transparency groups (a
constant-alpha soft mask instead of the writer's isolated opacity group),
knockout groups included.
doc: Node::blends_through / children_blend.

New Node.knockout_shape (transparency.set / object.setProps knockoutShape,
reported by transparency.info). In a knockout group such an object knocks
out only as much as its opacity and mask let through (a 50% object knocks
out 50%); otherwise its full coverage knocks out. The renderer, PDF and
SVG masks honour it, and the panel's checkbox is now live.

Knockout Group is now Knockout {Neutral, Off, On} (old files' true loads as
On, false as Neutral). In a knockout group each child erases what the
children below it drew where it paints, then adds itself, so it composites
against the group's backdrop; neutral plain groups pass their children
through to the enclosing knockout group. transparency.set / object.setProps
take knockout "on"|"off"|"neutral"|bool; transparency.info reports the
state. PDF and SVG write knockout groups as nested soft masks with the same
look (PDF warns); the Transparency panel has a tri-state checkbox.

Styles now store the object's opacity, blend mode, isolate and knockout and apply them.
New Graphic Style from a group without its own paint captures its topmost object's
appearance, and from type its characters' fill and stroke. Names are made unique.
graphicStyle.apply takes ids and add (Alt-click in the panel adds the style on top of the
existing appearance). graphicStyle.list reports every style. Applying links objects to a
stable style id (Node.graphic_style), which the management commands build on.

An appearance is basic with at most one fill and one stroke, none hidden or
with its own opacity, blend mode or effects, and no object effects; Reduce
to Basic keeps the topmost visible fill and stroke. The Layers panel fills
an object's target circle for any non-default transparency (blend mode,
isolation, knockout or an opacity mask: Node::has_default_transparency).
A multi-selection whose objects differ shows "Mixed Appearances" with no
rows. The Appearance panel's object row and the Control bar name the
selection from one source, and type objects are "Type". Expand Appearance
is only in the Object menu. Clear Appearance also resets the object's
opacity and blend mode. Tests cover addFill/addStroke, setItem/removeItem,
clear, reduceToBasic and graphicStyle.apply.

Clip groups clip by compound paths (with their holes), even-odd paths, text
outlines and groups (the union of their members) on screen, in raster
export, in SVG and in PDF alike, through one shared region:
Node::clip_outline (the model walk) and effects::clip_outline (text
outlined, several shapes united), cached per clipping path in the
renderer. Nothing to clip by hides the clipped art everywhere, and clicks
hit a clip group only inside its clipping region. Make Clipping Mask takes
a compound path or text object on top (it loses its paint) and Release
gives it back unchanged in kind.
