The CMYK rewrite matches krilla's exact output; if that ever changes,
the export says so instead of silently writing RGB groups.

krilla gives every transparency group it writes a DeviceRGB blending space,
including the group around a placed PDF page:
/Group<</Type/Group/S/Transparency/I true/CS/DeviceRGB>>
A print file therefore carried DeviceRGB (forbidden by PDF/X-4 under a CMYK
output intent) and blended CMYK art through RGB: a placed logo's black,
C91 M78 Y61 K97 in its own file, printed as C72 M67 Y67 K88. When the
document's transparency blend space is CMYK (the default for print) or the
export is PDF/X-4, the groups are rewritten to /CS/DeviceCMYK in place and
at the same length (the optional /Type/Group gives the room, the rest is
padded with spaces), only inside object dictionaries found through the
cross-reference table, so every offset stays valid. Booklets get the same.
Books merged by merge_pdfs are not covered.

A PDF/X-4 export (PDF 1.6) of a page with a placed PDF 1.7 (VectorCraft's
default, and most tools') failed at the very end with
designcraft-cli: PDF writer error: Pdf(PdfDocument(PdfDocumentRepr { .. }), VersionMismatch(Pdf17), None)
krilla refuses to embed a PDF newer than the file it writes. PDF 1.7 changed
nothing in how a page draws, so a 1.7 file now goes in as 1.6 (its header
relabelled, as qpdf --force-version=1.6 does) with a warning. A PDF 2.0
file, or one whose catalog declares 1.7, fails the export with a message
naming it. hayro-syntax moves from dev-dependencies to dependencies (krilla
already builds it) because the check names its PdfVersion.

[Paper] was written as DeviceRGB white (`1 1 1 rg`) even in print documents
and PDF/X-4 files: an RGB object in a CMYK print file, which print preflight
rejects. For the Print intent and for PDF/X it is now `0 0 0 0 k` (CMYK, no
ink, still knocking out what lies below); Web and Mobile documents keep RGB
white.

Rasters stay below vello_cpu's u16 limits (a 65535-pixel-wide render
panicked inside it), page renders larger than 2^29 pixels decline instead of
allocating, PNG encoding never panics, and the PDF heading tag can't fail.
Both crates deny the panicking lints.

- color: Swatch.hidden — unnamed colours (applied, not listed in Swatches until added)
- engine: object.color (reuses a swatch with the same colour, else an unnamed one; fill or
stroke), swatch.addToSwatches (optionally named; users follow the rename),
swatch.addUnnamed (+ test)
- UI: Color panel with fill/stroke proxy, CMYK/RGB/Lab, channel sliders with gradient tracks and
value fields, tint slider for named swatches, spectrum ramp, Add to Swatches; Color Picker
dialog (double-click a proxy chip); Swatches hides unnamed colours

- Edit › Paste Into (⌥⌘V): copied objects (with their stories and images) become the selected
frame's content, clipped by it; Item::is_group / has_nested_items; renderer and PDF draw fill,
clipped content, stroke; IDML nests the items inside the frame both ways (verified in
InDesign 2026) (+ tests)
- Polygon Settings: sides and star inset as engine preferences used by the polygon tools and
frame.create; double-click the Polygon tool (+ test)

- doc: OBJECT_MARK with Story::objects (items normalized to the origin) kept in sync on edits,
copy/paste slices and threading
- compose: inline objects are wide glyphs sitting on the baseline (Y offset; auto leading grows);
above-line objects push their line down; placements per frame follow vertical justification
- render + PDF draw anchored items with their lines
- engine: anchored.insert/options/release/list; pasting copied items into text anchors them;
Options/Release act on the object at the insertion point (+ test)
- Object › Anchored Object menu

- doc: ANCHOR_MARK / XREF_MARK with Story::anchors / xrefs kept in sync on edits, 11 formats
(InDesign's building blocks + partial paragraph), paragraph anchors, typographic quotes
- compose: anchor pages via an XrefIndex (cached per document signature); cross-references are
resolved at composition, so they never go stale; '??' for missing destinations
- PDF: cross-references become link annotations to the destination page
- IDML: export/import as HyperlinkTextDestination / CrossReferenceSource / Hyperlink /
CrossReferenceFormat (+ XRef page variables); verified live in InDesign 2026
- engine: xref.insert/list/setFormat/defineFormat/formats, anchor.create/list (+ tests)
- UI: New Cross-Reference dialog (styles → paragraphs, format); menu pass adding TOC, sections,
text variables, hyperlinks, footnotes, step and repeat, spelling, fitting/content submenus,
effects, Data Merge, Preflight, EPUB; fixed-parameter menu variants; ui.menu.invoke opens
generated dialogs; every-menu-entry-is-a-command test

- doc: FOOTNOTE_REF marker + Story::notes (kept in sync on insert/delete/thread), FootnoteOptions,
NumberStyle::Symbols, footnote text addressed like cell text (CellAddr::footnote)
- compose: notes numbered (continuous / restart per page, spread, section), composed at column
width, body text makes room, stacked at the column bottom with the rule above
- render + PDF draw footnote text; IDML export/import in InDesign's structure (verified in
InDesign 2026), FootnoteOption preferences
- engine: footnote.insert/options/list/setText/delete/goToReference (+ tests)
- UI: caret/selection in footnote text, Footnote Options dialog, Type menu entries; menu items
labelled '…' with parameters open a dialog generated from the command's params doc
- sample magazine carries a footnote

New crate designcraft-pdf (L3): pages or spreads with MediaBox/TrimBox/BleedBox,
parent items with per-page folios, fills (solid + gradient swatches), aligned/dashed
strokes, corner options, opacity/blend, simple drop shadow, clipped images (JPEG
passthrough), and real text: composed glyph runs with embedded font subsets and
Unicode mapping from the story. CMYK as DeviceCMYK, RGB as DeviceRGB, spot swatches
as Separation, [Registration] as /All. Crop/bleed marks and page info. PDF/A-2b via
krilla; PDF/X-4 writes PDF 1.6 (output intent TODO).
Engine command file.exportPdf {path?, pages?, spreads?, bleed?, marks?, standard?,
compressImages?, title?, author?} (base64 when no path), CLI --export out.pdf with
--pdf-options, File > Export PDF... in the UI.
