Open and Place read Affinity documents natively (.af from Affinity 3, .afdesign/.afphoto/.afpub from Affinity 1 and 2): layers and sublayers, groups, artboards with their names and backgrounds, Publisher pages side by side, curves with live corners, parametric shapes, compound shapes, clipping by nesting, vector and pixel masks, solid and gradient fills, strokes, fill layers, artistic and frame text, placed images (their original JPEG/PNG), pixel layers, embedded documents as their cached picture, opacity, visibility, locking and blend modes, at the document's resolution in points. Unsupported content (effects, adjustments, brushes, master pages, special shapes, Affinity-only blend modes...) is listed in the import warning, one line per kind. A file whose native data can't be read opens as its embedded preview with the reason, and that preview cannot be placed or used as a template or library. Save never writes back over the Affinity file and there is no Affinity export. The document semantics were fitted to the thumbnails Affinity embeds in 176 public documents. `cargo xtask corpus --affinity` fetches 22 public CC0/MIT/Apache-2.0 documents at pinned commits, sha256-verified; the new engine test renders each and compares it with Affinity's own thumbnail (0-4.4 of 255 mean difference, per-file ceilings). import_fuzz mutates a synthetic native document's stream and container through open, render and export; the fuzz crate gains a stream target.
