A native file whose images together pass IMAGE_BUDGET (4 GiB, or 20,000
images) opens without the images past it. They are intact in the file, but
saving it again wrote the archive from the images in memory, so every
save, autosave or `convert` onto itself deleted them for good. A 7.6 GiB
`.fig` converted to a 7.3 GiB `.figcraft` reopened with 1,312 of its 2,337
images: one save would have dropped the other 1,025.
Loading now tells images left out for the budget apart from damaged ones
(`Loaded::images_past_budget`). A tab opened or reverted from such a file
remembers the file, and saving over it is refused with a message that says
how many images would be lost and to save under another name; saving a copy
elsewhere works, and the original keeps its images. Auto-save skips the
tab instead of retrying and failing every minute. `figcraft-cli convert`
and `run --in X --out X` refuse to write over their input the same way.
The same file is matched by its resolved path, so `./a.figcraft` and
`a.figcraft` count as one (`file_access::same_file`).
The note for each image left out for the budget now says it stays in the
file, which can't be saved over without losing it. Damaged and missing
images keep the old wording: they can't be kept, and saving drops them as
before. The doc comment on report_lost_images said saving always drops
the images it reports, which is no longer true for budget ones, so it went.
This stops the data loss; it doesn't make such files editable in place.
Loading images on demand would, and is discussed in the issue this links.
Tests: the count and the note for both budgets; saving over the file
refused with the file unchanged, Save As then working, and saving back over
the original refused again; a snapshot encoded in the background refused
too; a tab without images left out saving as before. Checked by hand on the
7.3 GiB file with file.save, file.saveAs, convert and run --out.

A .sketch file opened from disk joins the recent files, where it had no
picture and a generic icon. FileKind::Sketch reads the preview.png Sketch
saves under previews/ (within the thumbnail caps) and gets the design-file
mark, like .fig. Test: sketch_files_show_their_preview_png.

Conflicts resolved keeping both sides: `.sketch` stays in `is_document`
(now via `OsStr::to_str`); ROADMAP and the parity, roadmap and
file-format docs keep main's headers and rows with the `.sketch` notes
and history rows added.

* M6: Dev Mode measurements kept on the canvas, a read-only layers panel
Measurements placed between two layers, along a side or to the layer
around one (devMode.addMeasurement / removeMeasurement / measurements),
stored on the layer they start from (saved, synced, undoable; old files
open without them), drawn in Dev Mode as labelled redlines that follow
the layers and listed, placed and removed in the Inspect tab. In Dev Mode
the layers panel only selects and expands.
* M6: Dev Mode measurements: explicit imports, a measurement row of its own (Sonar)
auto_layout's grid branch moves to grid_layout and grid_sizing (SonarCloud cognitive complexity).
unset() clears gridColumnsSizing and gridRowsSizing, so an instance layer with equal tracks no
longer reads back its main layer's track sizes.
color_alpha is the part of a solid paint's opacity that is its typed colour's alpha, not a flag:
binding a colour variable takes only that part out, unbinding puts the variable's alpha back in,
and REST import records it. A 50% paint bound to a 50% variable stays at 25% bound or not.
Board files (File > New board) with sticky notes, shapes with text, connectors that follow what they join (straight or elbow, arrowheads, labels), marker, highlighter and eraser, and stamps; a board toolbar and a contextual bar; the Design panel hidden on boards, Prototype and Dev Mode refused there. Boards are ordinary FigCraft files built from ordinary layers, so saving, undo, export, MCP and live sessions work unchanged. File tabs, recent files and Open files show a pen nib for design files and a note for boards (original icons drawn in code).
* Dev profile: line tables for workspace crates, no debug info for dependencies
* Tests: one integration-test binary per crate with several test files
* xtask ci: nextest, doctests, tests without examples, --keep-going; add xtask test
- --no-system-fonts holds for .sketch imports too: the CLI opts the
process out, so the import's font matching doesn't scan.
- Shared text styles get the installed family and platform tracking
their linked layers get.
- Each text run writes its letter spacing, line height and font axes,
neutral when it has none, instead of taking the first run's.
- The unsupported-drop hint and its catalogs list .sketch.
- A test sends damaged .sketch data through file.open and file.import.
- Stack items are matched to their source layers through a map.
- Docs: .sketch is a convert input; the Carbon kit's Sketch 47 edition
is refused (the 68 and 83 ones open).

Texts an auto layout places keep the layout's position (the next layout
pass would take the baseline move back). A faded layer's group takes the
layer's id, so stacks, links and overrides still find it; faded masks
stay masks. figcraft-format no longer depends on figcraft-layout.

Tinting copies a group's or master's layers; the copy is charged to the
import's work budget (past it, tints are skipped with a note). An
override handed to a nested instance costs its value's size, so deep
chains of large overrides can't be copied without end.

A tint or fill that isn't a JSON object is left alone instead of being
indexed. A structural fuzz replaces each value of a rich file with values
of other types and imports every variant.

Sketch draws an artboard's layout and square grids only while its layout
view is on; they now import hidden (still there, shown with the eye in
the Layout grid section).

Alpha masks only mask (no drawn copy of their fill); a progressive
opacity (Fade) becomes an alpha mask of its gradient over the layer;
linear gradients run square in pixels as Sketch draws them.

The font database knows each face's PostScript name; the Sketch import
finds the installed face a file's font names (CourierNewPSMT is Courier
New Regular) and reads the family from the name only when it isn't
installed. Text without a fixed line height takes the line Sketch draws:
ascent and descent rounded to whole pixels, the line gap left out, a
fifth more for classic Mac fonts, the baseline where Sketch puts it
(measured on sketchtool renders of 80 fonts).

Sketch keys a font's variation axes by the tag read as a number; they map
onto the text style's variations (a fontVariations key in the REST
mapping). Font references without font data only name the fonts a
document uses and no longer raise the embedded-font note.

Groups as frames and graphics, stacks as auto layout (instances laid out
by their stack), corners and per-side borders from the style, pins and
sizing, tints (layeringType, fillColor overrides), text colour and
visibility overrides, blur lists (progressive, glass), inner shadows in
the shadow list, angular gradients starting on the right, text sizing,
and texts an override changed measured again on open.

Compared with Sketch's renders of a Sketch 64 file. Resized instances lay
out their layers the way Sketch does (measured: pins share the change in
proportion, a fixed size keeps its centre's share, and files before format
110 just scale); masters' backgrounds show in instances only when Sketch
includes them; swaps to a missing symbol keep the original; artboards
don't draw a style they carry. Apple's system fonts are found under the
names designs use (SF Pro, SF UI Text and Display, SF Compact), the
optical size follows the text size for named styles too, and imported
text keeps the platform's trak tracking as letter spacing.

Compared artboard by artboard with Sketch's renders of a real Sketch 50
file (sketchtool, black-box). Shape groups whose children have no
operation are one compound path filled by the group's winding rule (read
from the layer), not a union: rings, map streets and icons keep their
holes. Filled open paths close, as Sketch fills them. Flips apply after
rotation. Text with a fixed line height sits where Sketch's line spacing
behaviour puts it. Edited ovals and rectangles keep their points. Bitmap
colour adjustments become image filters. scale 0 means unscaled. A local
test compares sample files with sketchtool's renders.

From the branch review: overrides that point at junk (shared styles that
aren't objects, text runs that aren't) no longer panic; symbol expansion
spends a work budget (JSON copied, overrides handed on to nested
instances, grouped once by their first path segment), so small files
can't expand into gigabytes; far path points stay in range; notes are
capped and de-duplicated with a set; shared styles are looked up by
index; a styled second mask's drawn copy isn't clipped by the first;
JSON members are refused past 100 times their packed size or 2 GB in
all, and an unreadable document.json keeps the pages.

Layers linked to artboards navigate there on click (back links go back,
slide animations slide), hotspots become transparent frames with their
link, flow-home artboards start a flow; export options become export
settings (scale, width or height, suffix); artboard layout and square
grids become layout grids, which instances show like their masters.
Smart Layout, stacks and locked overrides are noted once per file.

Shared layer styles become a paint style for their fills, a paint style
for their border colours (linked to strokes) and an effect style; shared
text styles become text styles (colour stays on the layers); local and
library copies alike, unused ones listed too. Layers link to them, keeping
their own values where they differ. Color Variables (swatches, also
library ones) become colour variables in a Color Variables collection,
with fills, borders and text colours bound to them.

Symbol masters become components, also those copied from libraries (on a
page of their own); instances carry their master's layers with their
overrides applied (text, nested symbol swaps and hiding, images, layer
and text styles, nested paths) and resize them by their constraints, so
editing a master still updates every instance. A symbol inside itself
stops with a note; instances of missing symbols are empty frames.

Text layers keep their string and styled runs (font, size, colour, line
height, letter spacing, decorations, text transform; ranges in UTF-16
units, clamped), paragraph alignment and spacing, vertical alignment and
how the box sizes. Fonts named by PostScript name become family and
style; the engine then matches families to installed ones ignoring
spaces (PingFangSC → PingFang SC). Fonts embedded in newer files are
named in the import report.

Sketch draws a clipping mask with its fills, borders and effects under
what it clips; a FigCraft mask only clips. A plain copy of such a mask
goes underneath it, so a light avatar circle with a white icon in it no
longer vanishes on a white artboard.

Sketch 51 and older files make masks from shape groups; the mask flag was
lost when the group became its shape or boolean operation, so a masked map
spilled out of its card.

Solid, gradient (linear, radial with its ellipse, angular) and image
pattern fills (tile, fill, stretch, fit); borders as strokes with the
first enabled border's width and position, dashes, caps, joins and arrow
ends; shadows, inner shadows, layer and background blurs; layer and paint
opacity and blend modes; clipping masks, wrapped in a group of their own
where Sketch breaks the mask chain; Display P3 documents. Shape groups
pass their style to the shape or boolean operation they become. Noise
fills, motion and zoom blurs are listed in the import report.

Paths become editable vector networks (handles, per-point corner radius,
open and closed, winding rule). A shape group with one shape becomes that
shape in the group's place; several combine as boolean operations, mixed
operations nesting from the left as Sketch applies them. Stars and
polygons stay stars and polygons while their points are the generated
ones, edited ones and triangles become vectors.

Artboards (and Sketch 2025 frames) become frames with their background
(white by default, as Sketch shows them), groups and graphics groups,
rectangles with their corner radii, ovals ellipses, bitmaps rectangles
with the image, slices slices. Positions accumulate through groups,
rotation and flips keep their direction, resizingConstraint bits become
constraints. Not yet mapped layer kinds are listed in the import report.

.sketch archives (document.json, meta.json, pages/*.json) open through
file.open, file.import, drag and drop, the CLI and MCP; files saved by a
Sketch older than 48 are refused with a message saying how to convert
them. Layers come in the next commits.

Instance swap defaults that name an in-file main skipped by the layer cap
were reported as "isn't in the file": only instance targets fed the
capped-mains list. Defaults now feed it too.
Cause: in the browser, exporting several layers started one download
per file. Chrome holds back every download after the first until the
site is allowed automatic downloads, so the other files didn't arrive.
Fix: file.exportLayers takes `zip: true` (without `dir`) and returns the
files together as one base64 zip `data`, written by a new
figcraft_format::zip_files (the workspace's existing zip dependency).
The UI asks for it when the platform saves by downloads and hands over
one `<document name>.zip`.
Test: ui-egui several_layers_download_as_one_zip (one download, a zip
holding both layers). It fails on the previous commit (two downloads).
A design-system .fig file (54 pages) stopped at 244 248 layers, the rest
of its pages skipped, and most of its instances came in as frames "of
components that aren't in the file", with the cap note shown twice.
- The layer budget follows the compressed canvas at 8 bytes a layer, not
32: design systems are mostly instances, which pack tightly. Files under
about 1.6 MB keep the 200 000 floor and the 2 million ceiling stays
(measured on synthetic files: about 5.4 KB and 19 µs a layer).
- The library copies the pages use (the file's hidden internal canvas) are
mapped before the pages: at the cap the pages' last layers are skipped,
not the mains their instances link to. The REST stage keeps building
pages first (its ids are first-wins) and allows for the wrapper frame of
each library copy, the one layer the mapper doesn't count; that layer
tripped the REST stage's own cap and repeated the note.
- Instances and swap defaults whose main is in the file but past the cap
say so instead of "aren't in the file" (en and es catalogs).
- The .fig import gives a note the mapper already gave only once.
Tests in fig/layer_cap_tests.rs: the budget for a #981-sized canvas, library
mains ahead of the pages at the cap, the note for a capped local main, and
a whole 210 000-layer file with one cap note and its library links kept.
All four fail on the previous code.
