The font database made one style per font file, so a variable font
such as Figtree[wght].ttf listed only its default instance (Light).
Faces now also yield their fvar named instances, each a style of the
family named by its subfamily name (the default instance is the face
itself; unnamed or duplicate instances are left out; axes and
instances read are capped). The system font scan reads the fvar table
beside the name table, so installed instances are listed before the
file is loaded and found by name and by PostScript name.
An instance face carries its axis settings: skrifa draws its outlines
and reads its metrics and advances at that location, harfrust shapes
with a ShaperInstance, so layout, the canvas, Create Outlines and hit
testing all use the instance. PDF export embeds it through krilla's
Font::new_variable, SVG @font-face through subsetter's
subset_with_variations: both write a static font of that instance.
Tests build a small variable font in code (test_fonts, via
write-fonts; no font file is committed) and check listing, resolving,
glyphs and advances, PDF and SVG export and damaged fvar/gvar tables;
Bahnschrift and Segoe UI Variable are checked where installed.

Save PDF > Output now applies: colours convert to a destination profile
(destination, or preserveNumbers keeping the numbers of colours already in
its model; grey stays grey; images and freeform gradient images convert
too; printer's marks don't). Profile inclusion writes ICC-based colour
spaces (CMYK with the destination's or the document's profile, RGB as sRGB,
grey), and transparency in CMYK output blends in the CMYK profile's space.
The output intent profile is embedded as the catalog's /GTS_PDFX output
intent with its condition, identifier and registry, and Trapped goes in
the document information (PDF/A keeps its own). A shared patch module
edits written PDFs (Lab spot alternates use it too).

- pdf/src/encrypt.rs encrypts a written PDF with the standard security handler: 128-bit RC4
(PDF 1.4, revision 3; PDF 1.5, revision 4), 128-bit AES (1.6) or 256-bit AES (1.7/2.0,
revision 6), every string and stream, plaintext XMP metadata when asked, the permission bits
(printing none/low/high, five change levels, copy, screen readers). Crypto from RustCrypto
(aes, md-5, sha2: MIT OR Apache-2.0, pure Rust, wasm).
- PDF/A and PDF/X refuse passwords; equal passwords and passwords the algorithm can't take are
refused.
- Opening: the permissions password opens RC4/AES-128 files too; editing data comes back from
an encrypted PDF opened with its password.
- Save PDF › Security: the passwords, permissions and plaintext metadata, the encryption level.

PdfSettings (serde, camelCase) is the Save PDF model: Standard, Compatibility
PDF 1.4-2.0, General (Preserve editing, Thumbnails, Fast web view, View after
saving, Create layers), Compression, Marks and Bleeds, Output, Advanced and
Security. PdfOptions = settings + pages, title and date.
document.exportPdf {path?, preset?, artboard?|artboards?|range?, standard?,
compatibility?, ...sections} -> {path|dataBase64, bytes, warnings} applies the
options over the preset (null keeps the preset's value); PDF/X, passwords,
PDF/A-2b at 2.0 and out-of-range values are refused; options accepted but not
applied yet come back as warnings. document.export {format: pdf} and
document.formats take and list the same options.
The Save PDF dialog (file.export.pdf, ui.savePdfDialog) has Preset,
Standard and Compatibility on top and a section list; it runs the export
before asking for a path, so bad options never open a save dialog.

Both writers now ask the shared stroke geometry how to write each stroke
(effects::stroke::for_writer): a plain stroke where that is exact, else the
canvas's filled outlines (arrowheads, width profiles, dashes fitted to corners,
dots with round or projecting caps), grouped under the stroke opacity when the
line and its heads overlap. Brushed strokes are written as their brush art.
Inside/outside alignment only applies to closed paths, so open paths export as
centred strokes. The PDF outside-stroke clip frame and the SVG outside mask now
cover the whole stroke reach (miter spikes, projecting caps). SVG stroke
gradients use the same paint box as the canvas. The svg crate docs no longer
claim arrowheads, profiles, brushes and effects are dropped.
