file.saveAs and document.save wrote a PDF-compatible .ai, but
document.export (and with it the CLI's run --export x.ai and convert
in.svg out.ai, and MCP's export) refused it as a format that can only be
opened, and --help didn't list it as writable.
The .ai encoder is now shared: save.rs's ai_params and encode_ai (a PDF
of every artboard with the PDF options, carrying the native document,
blank pages with pdfCompatible: false) serve Save As and the exports
alike. The .ai format is writable, so document.formats, --help and the
MCP export tool list it; an export leaves the document's own path alone.
Export As and Export for Screens keep leaving .ai to Save As.

Save As offers VectorCraft, VectorCraft Template, PDF, SVG and SVGZ and asks
for the chosen format's options before writing: SVG Options for SVG/SVGZ, the
Save PDF dialog for PDF (its OK finishes the save); on the web a Save As
dialog first names the file and picks the format. A document opened from or
saved as SVG/PDF remembers its format and options in one place
(DocState.format, save_options: the SVG options, or every Save PDF setting),
so Save writes it again; the result's warnings name what the format loses,
then the encoder's notes. Save a Copy writes "<name> copy.<ext>" and leaves
the path, title and modified state alone. Save is off for a clean saved
document, and Save as PDF... is in the File menu.
Engine: document.save, file.saveAs and file.saveCopy take {path?, format?,
options?, svg?} (SVG options also flat) and write linked images beside an
SVG; file.formatOptions reads a format's options. save_plan/save_with are the
one save path of every frontend, on the shared SVG encoder (one SVGZ path).
The template format is writable. Save panels get per-format filters, a folder
and a suggested name.

Preserve Editing (on in the VectorCraft Default preset) embeds the
native document in the PDF as an embedded file with a hash of the pages
it was written with. document.open of a PDF, .ai or .ait restores it
exactly (restored: true) and falls back to importing the artwork, with a
first warning saying why, when the pages were changed elsewhere or the
data can't be read; SVG and PDF share that fallback and its warnings.
The legacy drawcraft payload name is read too. vectorcraft_pdf gains
editing(), ImportReport.native and PdfOptions.native.
document.save / file.saveAs / Save a Copy write .ai (format "ai" or an
.ai path): every artboard as a PDF that always carries the document and
takes the PDF options; a restored .ai keeps its path so Save writes .ai
again, and .ait templates open their document untitled. The desktop
save dialog lists the formats Save writes. Choosing a standard turns
Preserve Editing off (PDF/A refuses it), Export for Screens and PDFs of
some artboards leave it out with a warning.
