The renderer kept the outline of a stroke under the address of the
stroke in the object's appearance, the bits of the width and the
tolerance level, and used an entry only when the entry held the object
being drawn. The slices of a gradient along or across a stroke were
kept the same way. Objects can share one appearance until one of them
changes it. Copies made by Duplicate Selection share the original's
appearance, gradients included. For objects without a gradient fill or
stroke, so do the art the renderer places for unstained symbol
instances, the copies a live repeat draws and copies made by
edit.duplicate. In each frame, the objects that share an appearance
replaced each other's entries. The renderer therefore outlined their
strokes again in every frame.
The two caches now key each entry by the address of the object as
well, and each object keeps its own outlines from frame to frame. Art
that the renderer makes again in every frame keeps the old key: symbol
art that placed_art does not keep, and the evaluations of live objects
and the art of objects with effects that their caches do not keep. The
copies in such art replace each other's entries as before.
vectorcraft-cli bench of 2,000 unstained instances of a symbol of
eight paths took 45.7 ms a frame on main and 31.1 ms with this change,
at 2880x1800 on 8 threads, and a grid repeat of the same paths, which
draws 2,000 groups, took 45.0 ms on main and 27.2 ms with this change.
The peak working set of a bench run on the instances went from 88 MiB
to 122 MiB. In the tests, each frame draws what a new renderer draws.
The renderer decoded images with the decoder's default 512 MB allocation
limit, so a 300 ppi roll (6614 x 59055 px, 1.56 GB as RGBA) that opens and
exports to PDF fine drew nothing in a raster export - a fully transparent PNG,
exit code 0, no warning. It now decodes with the allowance opening has (2 GB,
512 MB on the web), shrinks an image past a pixmap's 65535 px side to fit
instead of dropping it, and counts any image it still can't decode: a raster
export that drew fewer images than it should says so in its warnings.

In Outline view a template layer drew as outlines like any other, so a
picture placed to be traced turned into a box. It now keeps drawing in
Preview (dimmed as before) while the other layers are in outline.
The renderer kept the rasters of an object's drop shadows, outer glows
and filtered content (Gaussian Blur, Feather and the Photoshop-style
filters), and drew them again while the object, the zoom and rotation
and the ink plane stayed the same. The content drawn into a raster also
reads things outside the object: patterns, symbols, brushes, images,
document, layer and color settings, the knockout a group inherits, the
fonts, and the options the frame is drawn with. When one of them
changed, a renderer that had drawn the object went on drawing the
raster it had kept, made from the old values.
Each kept raster now records what its content was drawn from: which of
those things the object reads, found by walking the object when the
raster is made, and a hash of their values then. The renderer draws
the raster only while that hash is the same in the current frame. Once
a frame, the renderer hashes the document's patterns, symbols and
images. It hashes their art and pixels by the addresses of their
shared values, and it keeps weak references to those values while a
raster made with them is kept, so no other value can take one of those
addresses. A filtered raster also records the color channels its
filters split, and under De-Interlace the raster resolution.
A temporary release test timed the inputs of 400 kept rasters at about
10 microseconds a frame.
The renderer drew each symbol instance by copying its symbol's art,
staining the copy for a stained instance and moving every object in it
by the instance's transform, in every frame. The copies were new
nodes, so the caches the renderer keys by a node's address (cull
bounds, path geometry, glyph layouts, live-effect geometry) missed for
every object of every instance, and the copies stayed in those caches
until they were pruned. Stroke outlines missed as well, because their
cache uses an entry only when the entry holds the node being drawn.
The renderer copied and moved the art of inline graphics in type the
same way.
The renderer now keeps the art it places in a frame cache with a
64 MiB budget, under the address of the symbol's art, the transform,
whether strokes scale with it, and the instance's stain. When the art
is a group or a layer without an appearance of its own, the renderer
copies none of it in a frame whose instances and symbols did not
change, and the objects in it hit the caches keyed by their own
address (cull bounds and paths, glyph layouts, live-effect geometry).
The stroke-outline cache keys a stroke by its address in the
appearance. In the art placed for an unstained instance, each object
without a gradient fill or stroke shares its appearance with the same
object in the symbol's art. When a symbol has two or more unstained
instances, the renderer therefore still outlines the strokes of those
objects again for each instance in every frame. Moving or restaining
an instance, or editing its symbol's art, places that art again, and
the other instances keep theirs. Other art is placed again in every
frame, as before, and so is art that holds a symbol instance, type
with an inline graphic, an image, a placed document, a blend, an
envelope, a repeat or a raster effect. Art that holds type is placed
again when the fonts change.
vectorcraft-cli bench of a symbol of eight paths (three filled and
stroked, two only filled, three only stroked) shown by 2,000
unstained instances took 51.6 ms a frame on main and 32.3 ms with
this change, at 2880x1800 on 8 threads; the same paths in 2,000
groups took 26.0 ms. The peak working set of a bench run at that size
went from 150 MiB to 83 MiB. In the tests, a renderer that keeps
placed art draws the same pixels as a new renderer, and instances
draw the same pixels as groups of their placed art.
Each pointer move of a drag applies the move to the interaction's
snapshot, so the dragged object is a new node in every frame. The
renderer kept the rasters of an object's drop shadows, outer glows and
filtered content (Gaussian Blur, Feather and the Photoshop-style
filters) only for the same node, so every frame of a drag ran those
effects again. On main, a moved frame of texture_drag_perf (a CMYK
rounded rectangle at 190.07% and DPI 1.5 in an 1800 x 1500 view) took
112 to 197 ms in a release build.
The canvas now renders with RenderOptions::interacting while a drag or
a dialog's preview is in progress. When an object misses its cached
raster in such a frame, the renderer takes the raster an earlier frame
made for an object with the same id, slot and ink at the same zoom and
rotation, made by the same effects from content of the same size (to
within 0.000001 pt). It draws the object's content into a raster
placed as that one was and compares the pixels byte for byte (only the
alpha under a shadow or glow). For Feather it also compares the points
of the clip outline, to within 0.000001 pt. When they match, the old
raster is drawn at the new place, rounded to a whole pixel, as a pan
draws a cached raster. Content under De-Interlace never takes a moved
raster, and a raster made over moved rasters counts as moved itself.
A frame rendered without interacting never draws such a raster, or a
raster made over one: the frame after the drag runs the effects again
and draws what a fresh renderer draws. The canvas's cache key includes
whether an interaction is in progress. On the desktop, the canvas
sends the frame after an interaction to the render worker when the
frame shown drew moved rasters. Each cached raster keeps the content it
was made from, within the existing 512 MiB budget. The pixels kept
with a filtered raster take as many bytes as the raster, and the alpha
kept with a shadow or glow takes a quarter as many as the shadow.
texture_drag_perf now renders a drag's frames as the canvas does, then
the frame after the drag, and that frame once more with every raster
cached. A moved frame now takes 20 to 26 ms, close to the 18 to 25 ms
of the cached frame; the frame after the drag takes 110 to 189 ms.

Preferences › Appearance of Black › On Screen was stored and never read.
Display All Blacks Accurately (the default) shows pure CMYK black, black
ink alone at 100%, through the working CMYK profile, a dark grey, as the
canvas always did. Display All Blacks as Rich Black now shows it on the
canvas as RGB black: fills, strokes, type, gradient stops, effect colours
and pattern tiles, and in CMYK documents drawn by ink planes a pixel
whose inks come out as black ink alone. Rich blacks, black tints and
placed images show the same either way; exports and printing are
unchanged (Printing / Exporting is a separate option).
The renderer gets RenderOptions::rich_black, painted with a new
Ink::RichBlack (screen colours with pure black as RGB black) and applied
by ink::compose. The canvas sets it from blackOnScreen and keeps it in
its cache key, so changing the preference redraws.
A headless frame test reads the canvas raster: K100 shows its profile
grey by default, RGB black with rich, a rich black unchanged, and grey
again with accurate. A render test covers the opaque and ink-plane paths
and checks that rich blacks, tints and images don't change.

Rarely set fields move into one optional boxed NodeExtras, and large NodeKind payloads (images,
live shapes, blends, envelopes) are boxed. Every object, and every undo step that copies it,
shrinks: a 50k-path move keeps ~24.5 MB per step instead of ~40 MB. Files stay byte-identical
(Node keeps its flat JSON through a borrowed Serialize and a from-wire Deserialize, no flatten),
and loading is slightly faster. Undo and redo reuse their step's size estimate instead of
walking the document again (8.3 -> 5.6 ms for a 50k-path move).

Text geometry, clips, clip paints, effect art, brushes, live effects, pattern tiles and freeform
grids were capped by entry count and cleared wholesale on overflow, so a document past the cap
(e.g. more than 4,096 type objects) recomputed every entry on every frame. A FrameCache keeps
per-entry byte sizes and last-used frames, drops the least recently used entries of earlier
frames, and sweeps stale ones. Text geometry keeps its glyph outlines once instead of twice.

Decoded images were kept per Renderer at full resolution and never evicted, so the canvas,
render worker, thumbnails and panels each held their own copy (96 MB per 24 MP photo).
They now live once in a process-wide LRU store keyed by content, with optional mip levels
(RenderOptions::image_mips, off by default so exports stay identical). Thumbnail renders
now sweep their caches, and shadow/effect rasters share a 512 MiB budget and match by Arc.

The automatic rasterizer thread count was one per core up to 4. On a 10-core Apple M2 Pro, 8
workers are faster (9 are slower again), and vello_cpu draws the same pixels with any number:
- fit page, 50,000 paths: 66.7 → 56.6 ms; after a pan 66.4 → 51.2 ms
- 400 % zoom, 50,000 paths: 17.8 → 15.7 ms (back under its 16 ms budget)
- fit page, 100,000 paths: 137 → 105 ms; 400 % zoom 33.0 → 25.8 ms
Machines with 5 cores or fewer keep their count, and Preferences → Performance and
VECTORCRAFT_RENDER_THREADS still override it. pixels_do_not_depend_on_the_thread_count renders
a page of live effects and 400 overlapping translucent objects with 0, 1, 4 and 8 workers and
gets the same pixels.

A node with live geometry effects (Offset Path, Outline Stroke, Warp, Transform, Roughen…) had
them computed again on every frame: Offset Path's curve offsetting and boolean sweep for every
object, every time the canvas redrew. Rendering 2,000 paths that each have Offset Path, warm:
175 → 11.8 ms.
The renderer keeps each node's effected geometry, and each appearance item's own geometry
effects on it, keyed by the node's Arc identity like its other per-node caches. The entry keeps
the Arc alive, so a hit is exact and an edited object (a new node) gets new geometry. Only the
node draw_arc is drawing uses the cache: its path comes from the node alone, so its effects give
the same result every frame. Entries not drawn for three frames are swept like the rest.
cached_effect_geometry_draws_the_same_pixels renders a page of Offset Path, Roughen + Drop
Shadow, Warp + Outline Stroke and Transform objects (with item-level Offset Path) cold, warm,
after a pan and with a fresh renderer, and gets the same pixels each time; after an edit, the
warm renderer draws what a fresh one does. Keying the cache by node id instead of identity fails
it. The render suite (216 tests, golden images included) passes unchanged.

A property test of the importers (import_fuzz) crashed CI with
STATUS_STACK_BUFFER_OVERRUN: a shape with coordinates in the 1e20s from a
mutated file made vello_cpu either panic in flatten_simd on a rayon
worker (rayon then aborts the process, so the engine's panic guard never
sees it) or ask for a 132 GB allocation, which aborts too. A malformed
file could end the app and lose the user's work.
draw_shape now leaves a shape undrawn when its control points, through
the view, aren't finite or reach past 1e10 pixels, or a visible stroke
is that wide (MAX_DEVICE). A document's art stays within 4 million
points, 2.6e9 pixels at the closest zoom, and vello was checked safe
with 90,000 random shapes within 1e9 pixels and 30,000 within 1e12.

Asset Export, File › Export, Save for Web and Object › Rasterize drew
each shape with its own smoothed edge, so where two shapes met edge to
edge (Divide, Shape Builder, abutting art) both half-covered the pixels
on the line and the background showed through as a thin ghost border.
With Art Optimized (the default) these now supersample, as the option's
name in Illustrator says: the art is drawn with hard edges at four times
the size (three or two times for large images, within a 40-megapixel
budget and the renderer's 65,535-pixel side) and each block averaged
into one pixel. Pixels shared by two shapes are fully owned by one or
the other at the finer size, so no seam is left, and the outer edges
are still smooth. The canvas keeps shape-by-shape smoothing for speed;
None and Type Optimized are unchanged.
RenderOptions::supersample turns it on (exports and Rasterize set it).
A render test checks two triangles sharing a diagonal: a seam with
shape-by-shape smoothing, none supersampled, and the factor's limits.

The renderer composited in 8-bit integers, so where a partly transparent
anti-aliased edge crossed opaque art (or a background colour) the result
came out at alpha 254 on some pixels, and PNG, TIFF and WebP files were
written with an alpha channel. Raster exports (and Save for Web) now
composite in floating point (vello_cpu's f32 pipeline, enabled as a
feature), offscreen groups, masks and patterns included; the canvas keeps
the faster 8-bit path.

While a group or layer was isolated, clicks, hovers and drags still
reached the art outside it, and that art drew as usual. Now only the
isolated container's contents hit: the art around it is locked and
clicks pass through it. On the canvas it draws at half opacity, above
the group as well as below, each run of it as one dimmed layer.

Gaussian Blur and Feather drew through a filter layer whose blur works on
a coarser grid tied to the canvas: the blurred art moved by up to about
a pixel, and its steps showed, as the view moved by parts of a pixel
(scrolling, zooming about the pointer). They now blur the content's own
pixels on the CPU, as the Photoshop-style effects already do: the same
look wherever the view is, cached while only the view moves.

The styles were stored on the text and written to SVG's text-decoration,
but the type was drawn without the lines. vectorcraft_text::decorations
now gives each underlined or struck-through stretch of a run on a line
its bar, placed and sized from the font's own underline and strikeout
metrics (with fallbacks for fonts that have none). The canvas, Create
Outlines, PDF export (outlined and real text) and SVG's outlined text
draw them in the run's paint.

A font library can hold two versions of one family and style (a new
Montserrat-Bold.ttf beside an old montserrat.ttf). The font database kept
only the first one loaded, so type set in the other couldn't be matched
when a PDF or .ai was opened: it came in as outlines. Now every version
loads (the first stays the one family and style resolve to), PDF import
tries the other versions when the glyphs differ, and type set in a version
the family and style alone wouldn't pick names it in CharStyle::font_version
(left out when None, so documents without it are unchanged). Layout,
shaping, the substituted-glyph highlight, Find Font, Package and Document
Info follow it; changing the font clears it.

A PDF's DeviceCMYK image opened as RGB (the interpreter's pixels as a PNG),
so every export wrote it as DeviceRGB or ICC RGB, silently. Images now keep
their CMYK samples, as CMYK colours already did:
- Model: CMYK images are blobs holding CMYK samples, a four-component JPEG
(Adobe's inverted samples) or a Deflate CMYK TIFF. vectorcraft-doc's cmyk
module reads their ink amounts (ImageBlob::is_cmyk, ::cmyk, capped at 64
megapixels) and writes the TIFF (ImageBlob::cmyk_tiff).
- PDF import: DeviceCMYK, CalCMYK and four-component ICC images keep their
samples. A JPEG with Decode [1 0 1 0 1 0 1 0] is kept byte for byte; any
other is decoded (8 or 16 bits, its Decode array applied) and stored as a
CMYK TIFF. Masked CMYK images and 1/2/4-bit ones open in RGB with a warning.
Placing a CMYK TIFF keeps it CMYK too.
- PDF export: CMYK images are written in CMYK (DeviceCMYK, or ICC-based with
the CMYK profile when colours are tagged: PDF/X-3, PDF/X-4, PDF/A). A CMYK
JPEG neither resampled nor recompressed passes through unchanged; others are
resampled in CMYK and compressed as ZIP or as a CMYK JPEG (jpeg-encoder,
which also replaces the ZIP fallback and its warning for images converted to
CMYK). Output conversion treats them like CMYK colours: Preserve Numbers and
PDF/X-1a keep their numbers, Convert to Destination converts them to another
CMYK profile or to RGB through a 17^4 lookup table (cms::CmykLut, now also
behind the renderer's ink table). A CMYK image that can't be decoded is
reported in the warnings.
- Canvas: CMYK images show through the working CMYK profile, as CMYK fills
do, and paint their own inks in ink planes (CMYK raster exports, CMYK
blending). SVG export writes TIFF images as PNG.
Illustrator's Output › No Conversion keeps colour data as it is
(https://helpx.adobe.com/illustrator/using/pdf-options.html).

Documents made elsewhere often name a font differently from the family
name VectorCraft lists: a localized family name (ヒラギノ角ゴシック), a
legacy family/style pair (Hiragino Sans + W3) or a PostScript name

and resolves a request to the right face, telling the caller whether it
matched exactly, by another name, by substitution or not at all
(FontMatch).

- engine: text.fonts reports status, the resolved face and missing

- Images distort as a raster mesh warp: cut by Fidelity into triangles,
each a clipped image under the affine map of its corners (pieces overlap
slightly, no seams; the renderer paints them without clip layers; SVG
writes the pixels once and <use>s them).
- Symbol instances distort as their symbol's art (the renderer's cache
follows edits to the symbol).
- Distort Appearance bakes strokes (filled outlines) and geometry effects
before bending; Distort Linear Gradients bends linear gradients; Distort
Pattern Fills bends the tiles. Opacity masks of the content bend too.
- Bug fix: a rotated, sheared or reflected warp envelope re-warped along
the page axes. Envelopes now keep their own frame (append-only model
field), so the warp turns with the art; move and scale keep it square.
- Live evaluation shares one set of hooks (vectorcraft_doc::live::Hooks,
vectorcraft_effects::{expand_live, expanded_live_group,
expand_live_deep}) between the canvas, Expand and every exporter.

Type > Font, the Character, Properties and Glyphs panels and Find Font list
every installed font by default, as the reference app does, instead of the
four bundled families. The family dropdowns get a search field that filters
the list as you type (Enter picks the first match) and open on the current
font. Show System Fonts, which no longer means anything, becomes Refresh Font
List (text.rescanFonts): it picks up fonts installed since the app started and
redraws type set in them without editing the document. text.fontList lets MCP
agents list the families and a family's styles.
Root cause: the font lists came from FontDb::families(), which only held the
bundled fonts until something scanned the system fonts (fixed with #130). The
Type > Font menu, rebuilt every frame, now builds its items once per font
change, and renderers lay type out again when the fonts change.

The issue asked for non-destructive colour adjustments in the Effect menu
and the Appearance panel that work on vector paints, live type and
embedded images. Only the destructive Edit Colors commands existed, and
the live-effect pipeline only knew geometry and raster effects.
Effect > Color Adjustments adds six effects (adjust.*). They recolour,
in stack order, everything an object paints with: fills and strokes
(gradient stops too), type, gradient meshes, embedded images and a
group's members, each colour keeping its model. The Edit Colors walk over
an object's colours moved to vectorcraft_doc::recolor so the commands
and the live effects share it. The renderer draws adjusted art through
its object-effect path (recoloured images cached within a memory
budget), exports bake the adjusted colours (images as recoloured
copies), and Expand Appearance makes them permanent. The effect dialog
shows sliders, a channel menu and a draggable Curves graph, all previewed
live as one undo step.

PDF export now renders the shadows, glows, blurs and feathers of groups,
layers, type, images, symbol instances, live objects and single fills and
strokes (and those inside opacity masks, symbol definitions and pattern
tiles) as images at the document raster effects resolution, instead of
leaving them out with a warning. Shadows and outer glows go under the
untouched vector art; a path whose fills or strokes carry effects is
written as one piece per fill and stroke. Expand Appearance shares the
image helpers (moved to rasterfx.rs); effect images now cover what the
renderer paints (members' shadows included).

document.export {format: "jpg"} takes colorModel (rgb|cmyk|gray), quality 0–100, method
(baseline|optimized|progressive), scans (3–5), embedIcc and imageMap (none|client|server).
JPEGs are written with jpeg-encoder. CMYK files hold ink amounts drawn as the renderer's ink
planes, so CMYK colours keep their inks (black type stays black ink alone). Profiles are made
in code from the CMS (cms::icc_bytes): the RGB spaces from their primaries, the CMYK spaces as
Lab lookup tables sampled from their model, a grey with sRGB's tone curve, and loaded
profiles as loaded. Image maps write <stem>.html or <stem>.map beside the image for objects
with a URL and an Image Map shape. The JPEG Options dialog gains Color Model, Quality 0–10,
Method and Scans, Image Map and Embed ICC Profile; CMYK documents default to CMYK.

A linked image (`ImageObject.link`, now a LinkInfo: absolute path, path relative to the document,
size, modification time, hash, page; old path strings still load) keeps a low-resolution preview
(`ImageBlob.proxy`, at most 256 px a side) that a native save writes in place of the pixels of
images only linked images show. Opening a native document reads the linked files again, looking
for each at its path, then relative to the document and by name in its folder: missing files
show their preview, modified ones are read again only with Update Links: Automatically.
`document.open` reports `missingLinks`, `modifiedLinks` and `updatedLinks`.
links.check reports each link's status, links.update reads modified files again and
links.relink points images at another file or at same-named files in a folder (each keeps its
bounds; one undo step). In the app, a document opened without its linked files asks about each
(Replace…, Ignore, Apply to All), then offers to update modified links when the preference asks.
The renderer caches previews apart from the file's pixels; the Eyedropper samples previews in
the object's pixel space.

PNG is written by an in-code chunk writer with the resolution in pHYs and optional Adam7
interlacing (JPEG stores the resolution in JFIF). document.export takes ppi (72/150/300/other,
wins over scale), background (transparent, white, black or a colour) and antiAlias (none, art,
type: text snapped to whole pixels); Export for Screens rows take them too (plus one top-level
antiAlias, and a row's ppi names its @Nx suffix), and so does object.rasterize. Hard edges stay
hard in every offscreen pass (groups, masks, filters), whatever the thread count.
RenderOptions.anti_alias and render::encode::RasterExportOptions; PNG/JPEG/WebP Options dialog
(pngOptions/jpgOptions/webpOptions) after File > Export As PNG.

File > Document Setup is a tabbed dialog over one engine command,
document.setup (no params: a query; any keys: one undo step;
document.setUnits stays as the units alias).
- General: units, bleed (four sides with a link toggle), Edit Artboards,
Show Images in Outline Mode (greyscale pixels under the frame),
Highlight Substituted Fonts/Glyphs (pink boxes on screen only).
- Transparency: grid size and colour presets or custom colours, Simulate
Colored Paper, the flattener preset (built-in or saved) and Discard
White Overprint (Overprint Preview keeps white overprints visible).
- Type: language with its quotes, Use Typographer's Quotes for the Type
tool and Smart Punctuation, superscript/subscript size and position and
small caps size (Character panel position/smallCaps; changing the
setup restyles the text in the same undo step), text export (SVG text
as text or outlines by default).
- The canvas draws a red bleed outline and the grid in the document's
colours and cell size as one textured quad, also in rotated views; a
white Background Contents exports raster formats opaque.
Model: Document.setup (DocSetup, defaulted, skipped when default) and
CharStyle position/small_caps; old files load unchanged.
tests_transparencygrid's helper now finds the grid by its texture (the
grid is one textured mesh instead of per-cell rectangles).

Shipped code no longer unwraps, expects or panics: every one of the 124
unwrap()/expect()/panic!/unreachable! sites outside tests now handles the
failure (Result/Option, ?, let-else, defaults) and reports errors to the user.
- Lints: workspace clippy denies unwrap_used, expect_used, panic, todo,
unimplemented and unreachable; clippy.toml allows them in tests, and
integration tests, examples and testkit opt out explicitly.
- Safety net (vectorcraft_engine::guard): a panic in a top-level command rolls
the document back and returns EngineError::Internal; a panicking tool is
reset; the MCP server answers with an internal error and keeps serving; the
UI frame and each control request are guarded.
- APIs that hid failures now return them: Rendered::to_png/to_jpeg/to_webp
return Result (JPEG/WebP errors used to write empty files),
FontDb::face returns Option, Region::top returns Option.
- Fuzzing: engine/tests/import_fuzz.rs feeds garbage, hostile and mutated SVG
and PDF through import → render → export (30k cases locally, no panics).
- Docs: AGENTS.md/CLAUDE.md rule, docs/development.md "Robustness" section,
README pointer and a PR template checklist.

The Gradient panel's Stroke buttons now work: with the Stroke proxy on a
linear or radial gradient they lay it within the stroke (placed on the
page, as before), along the path (start to end of each subpath) or across
it (left edge to right edge; inside/outside strokes span their visible
side). `paint.editGradient {stroke: true, strokeMode}` sets it (new art
too with nothing selected); `document.inspect` reports
strokeOptions.gradientMode. Model: StrokeLayer.gradient_mode (default
Within, not written).
Shared geometry in effects::stroke::gradient: ribs on the bisectors of
the flattened path (fans round sharp corners, widened under arrowheads,
following width profiles) cut slices each painted with a linear piece of
the gradient (Gradient::span). The canvas and raster export clip them to
the stroke's outline and arrowheads, grown a pixel and composited with
copy so there are no seams and translucent stops paint once. SVG and PDF
write the same slices clipped to the outline, with a warning (new
vectorcraft_svg::export_with_report). Outline Stroke and Expand make
gradient meshes clipped to the outline. Mesh quads now grow along their
edges so thin quads show no seams. Dashes, profiles and arrowheads keep
working in both modes.

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.

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).

transparency.viewOpacityMask {on?, id?} shows only the opacity mask on the
canvas as greyscale coverage (luminance, clip and invert applied; the rest of
the art hidden) and enters mask editing; called again it shows the artwork and
keeps editing. The Transparency panel's mask thumbnail runs it on Alt-click and
is outlined in the accent colour while the mask is viewed. The state is
DocState.mask_view (shown while that mask is edited: DocState::shown_mask) and
reaches the renderer as RenderOptions.mask_view.

Object > Pattern > Tile Edge Color... picks the colour of the tile edge
(a layer-colour preset or a custom colour), stored in the preference
patternTileEdgeColor and passed to the renderer. Pattern Options gains
Show Swatch Bounds: a dashed outline of the part of the tiling the swatch
repeats (the period of brick and hex tilings).
Commands: prefs.set {patternTileEdgeColor}, pattern.options
{showSwatchBounds}, ui.tileEdgeColor. Model: PatternDef.show_swatch_bounds.

object.flattenTransparency {preset?|options, ids?} splits the targets into groups of overlapping
objects. Groups with transparency become atomic regions (faces of the arrangement of every fill,
outlined stroke and clipping path) filled with the colour the renderer composites there: blend
modes, group opacity, isolated and non-isolated groups, knockout groups and knockout shapes, over
white or (Preserve Alpha) over nothing. Regions reached by gradients, patterns, images, opacity
masks or raster effects are rendered into one image per group, under the regions, clipped to
them with Clip Complex Regions. The raster/vector balance rasterizes whole groups past its region
budget (all at 0). Options and presets live in FlattenOptions; single visible paints keep their
colour and overprint; text and strokes can be outlined everywhere. One undo step.

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.

With type selected, stroke.set (without an item) gives every run the
weight, cap, join, miter limit and dashes instead of adding an object
stroke; while the Type tool edits text, the Stroke panel styles the
selected characters through text.setRangeStyle `strokeOptions`, and the
panel reads the first run (or the selection's style).
CharStyle gains stroke_cap, stroke_join, stroke_miter_limit and
stroke_dash (defaulted, skipped when default). Character strokes and
object strokes on type now draw through the shared stroke geometry on
the canvas, in PDF and in SVG (live text writes cap/join/miter/dash and
tspans reset what the first run sets; object strokes are drawn on the
glyph outlines), so every stroke option, opacity and blend applies.
Outlines, the Eyedropper and graphic styles keep the options.
