PDF export gains print options, saved on PDF export settings and taken by file.export, file.exportLayers, file.exportFramesPdf, export.add / export.update, figcraft-cli export and the MCP export tool: - a bleed (points or a length like 3mm / 0.125in, up to 2 in) that grows each page and shows what lies past the frame: its fills reach out to the bleed edge and its children are clipped there instead; a print page of one frame is trimmed to the frame's box; - crop and bleed marks: 0.25 pt hairlines outside the bleed in registration colour; - MediaBox / BleedBox / TrimBox; - CMYK colour: fills, strokes, text, gradient stops, images and rasterised effects converted from sRGB with the naive, deterministic K = 1 - max(R, G, B) formula; DeviceCMYK without an output intent (no CMYK ICC profile can ship in the repository), soft masks stay RGB. The Design panel shows a PDF row's print settings as a summary line that opens them; the Export dialog has print options for its PDF preset. Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>
