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
(HiraginoSans-W3). FontDb now indexes every name in a face's name table
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).
- text: FaceKeys/aliases, FontDb::resolve, canonical, find_postscript;
fix a race where a face loaded by another thread was reported missing.
- engine: text.fonts reports status, the resolved face and missing
glyphs; Replace Font resolves the same way.
- render: substituted-font highlighting uses resolve, so a font found
by another name is no longer shown as missing.
- Find Font notes how each font was found.
- Preferences › Type › Include Fonts of Other Design Apps' Folders
(macOS, on by default).

- 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.

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.

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.

color::blend gains blend_rgb (the 16 blend functions, with the 0.3/0.59/0.11
luminance of the non-separable modes), composite (source-over with blending)
and the shared opacity-mask luminance weights. Exported SVG masks take
luminance from sRGB values (color-interpolation="sRGB"), as the canvas does.
Tests: a per-mode table on the canvas (object, fill and group blend modes,
within 1/255; Exclusion 2/255 in the rasteriser's 8-bit pipeline), the same
table through SVG export rendered by resvg, clip and invert masks against the
canvas, and every mode's PDF name read back.

Fill and stroke layers (and type characters' fill and stroke) carry an
overprint flag. object.setOverprint {fill?, stroke?, item?, ids?} sets it
(groups: their contents; type: its characters too; one undo step, none when
nothing changes) and attributes.info reads it back (null where mixed).
Overprint Preview and Separations Preview draw overprinting fills and strokes
with Multiply. The old Document.unknown["overprintBlack"] id list migrates to
the new flags on load; Overprint Black now sets the flags.

Geometry effects reach objects that aren't paths through their outlines (vectorcraft_effects::
reshape: glyph outlines, evaluated live art, the symbol's art, an image clipped by its reshaped
frame), applied to the whole art as one piece; the renderer caches that art per object and
paints raster effects around it in the same filter layers paths use (shared Renderer::raster_fx,
also used per fill/stroke). Exports bake the reshaped art; SVG writes per-item filters; PDF
warns about raster effects on strokes as well as fills and objects.

New Document.page_isolate / page_knockout, set by
transparency.togglePageIsolatedBlending / togglePageKnockoutGroup {value?}
(one undo step each, saved with the document, reported by
transparency.info) and the Transparency panel menu's check items. The page
renders as an isolated group (top-level blend modes no longer blend with
what lies under the page) and/or a knockout group whose elements are the
layers (neutral layers pass their objects through). PDF and SVG wrap the
page content in an isolated group and write page knockout as soft masks.

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.

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.

Clicking an Opacity row in the Appearance panel (a fill's or stroke's, or
the object's) opens a popup with the same blend-mode dropdown, opacity
field and slider as the Transparency panel (widgets::opacity_blend), and
edits that item through transparency.set. The blend-mode dropdown draws a
separator between the BlendMode::group() groups, also for the blend-mode
parameters of effect dialogs and inline effect editors. Fills and strokes
of type objects composite with their own opacity and blend mode.

Hollow heads draw as rings (the open arrow as a chevron) and closed paths get
no heads. The stroke stops under each head, so it never shows through a hollow
head or past the tip; stroke.set {arrowAlign: "extend"|"tip"} chooses whether
the tip extends past the end point (default) or sits on it with the stroke
shortened. Line and heads share one paint box (a gradient runs on into the
head) and take the stroke and object opacity once, as one layer on the canvas
and one group in PDF. StrokeLayer.arrow_align is a new defaulted field, so
older files load unchanged. The Stroke panel's Align buttons get two generated
icons and are disabled when the stroke has no head.

Arrowheads, width-profile outlines and dashed line outlines now come from
vectorcraft_effects::stroke (stroke_pieces, line_outline, width_outline), used by
the canvas and PDF export alike; the renderer caches profile outlines too. Width
profiles are a doc-level catalogue (WidthProfile::PRESETS, preset, preset_id,
id_of) shared by stroke.set and the Stroke panel; stroke.set rejects unknown
profile ids and its params doc lists the arrowhead names.

PNG/JPEG/WebP export renders the artboard at the requested scale with no size check. The CPU
rasteriser addresses at most 65535 pixels a side (and panics at that edge), so a large artboard at
a print resolution, e.g. the maximum 16383 pt artboard at 300 ppi (~68 000 px), or a screenshot at
scale 16, panicked inside vello_common: the desktop app or the MCP server exited and unsaved work
was lost.
`vectorcraft_render::raster_size` checks the pixel size first (at most 32 768 px a side and 268
megapixels, like Rasterize already refuses oversized images) and the export paths return an error
that names the size: `document.export` / `exportSelection` / `serialize`, the MCP `export` and
`screenshot` tools, File ▸ Export and the control protocol's `ui.render`.

A dash pattern with a negative value (for example [-5, 3], from `stroke.set` or a PDF `d`
operator) was handed to the dasher whenever any value was positive. When the values sum to zero
or less the dasher never advances, so rendering the document hung forever (canvas, screenshot,
PNG/JPEG export, `vectorcraft-cli convert`).
PDF (32000-1 §8.4.3.6) and SVG (`stroke-dasharray`) both define such a pattern as invalid and the
stroke as solid. `Dash::is_dashed` now says whether a pattern draws dashes (finite, non-negative,
not all zero), and the renderer, the width-profile outline, the SVG and PDF exporters and the PDF
importer use it, so an invalid pattern is drawn, written and read back as a solid stroke everywhere
(the PDF exporter used to clamp negatives to 0, writing zero-length dashes).
