Place: Bounding Box measures only the art that shows

With crop "bounding", file.place measured the placed art by each
object's visual bounds, which include the hidden members of a group.
A group holding a 40 pt square and a hidden 170 x 42 pt rectangle was
measured as 251 x 123 pt: at, rect, the place cursor and
file.place.info all used that box. A group whose only part on the page
or artboard was a hidden member was also placed, and symbol instances
were measured as a 20 pt square.

The art's box now follows the rule exports use
(vectorcraft_render::encode::drawn_bounds, made public): hidden
objects, guides and template layers do not count; the reach of effects
such as a drop shadow now counts; symbol instances are measured by
their art. The same rule picks the objects on the page or artboard.
Hidden objects on the page or artboard are still placed, and stay
hidden. Replace and the width and height that file.place answers also
measure symbol instances by their art.

   - Affinity documents in (AF.1–AF.4): `.af` (Affinity 3) and `.afdesign`/`.afphoto`/`.afpub` (Affinity 1 and 2, container versions 8–12) open and place as editable art: layers and sublayers, groups (pass-through or isolated), artboards (with their names and backgrounds) and Publisher pages side by side, curves with live corners, parametric shapes (rectangles with corner radii, ellipses, polygons, stars, pies, triangles, trapezoids), compound shapes, solid/linear/elliptical gradient fills and strokes (weight, dashes, alignment, scale-with-object), clipping by nesting, vector and pixel masks, artistic and frame text with fonts, sizes, tracking, leading and alignment, placed images (their original JPEG/PNG) and pixel layers (8/16-bit RGB, CMYK), opacity, visibility, locking and blend modes, at the document's resolution in points. Effects, adjustments, brushes and pressure profiles, transparency gradients, master pages, symbol instances (imported as their cached picture), special shapes (cloud, heart, cog…, imported as ellipses) and Affinity-only blend modes are named in the import warning. A file whose native data can't be read opens as its embedded preview with the reason, and that preview can't be placed. Save never writes back over the Affinity file and there is no Affinity export. AF.4 adds Affinity 3 artboard recognition and actual-outline clipping, source-backed JPEG/PNG raster tiles, Unicode text-run recovery, stored fallback/exact installed fonts, OpenType feature flags and compound-geometry limits. 51 public CC0/MIT/Apache-2.0 files (33 current `.af`), pinned and sha256-verified (`cargo xtask corpus --affinity`), test native retention and every-board native/SVG/PDF/PSD output for current files; selected files compare their saved thumbnails.

   - Placed documents: File › Place of a `.vectorcraft` file links to it by default (`file.place`'s `link`): one locked object showing an artboard of the document (or its art's bounds), read the way placing it without Link reads it, its symbols, patterns and images kept apart from the document's; without Link (or from bytes, not a file) it is an editable copy as before. It stays vectors in every output (SVG, PDF, EPS, EMF, DXF), and so do placed documents inside it, read from their own files up to 8 levels deep (documents that place each other stop there). On screen they draw from bitmaps cached per file and zoom step, shared by every copy and made in the background (a placeholder until ready), so a sheet of them redraws in about a millisecond; exports and prints draw them exactly. Like linked images, a save keeps only a preview of each (JPEG when opaque) unless Include Linked Files; output, and zooming past the preview, read the file again, falling back to the preview with a warning when it is gone or changed. Saves for older versions write them as plain art. Links check, update, relink, Update Links on open, Link Info (the artboard's size), Placement Options, Break Link (also Embed, Object › Expand: the editable copy placing without Link gives, its resources joining the document), Edit Original (the document in a new tab) and the Links panel cover them; saving a document updates the open documents that place it. The native format (v4) keeps data of 8 KB or more after the JSON instead of base64 in it.

   - Desktop print transport uses `craft-print` for CUPS and modern Windows. Sheet composition, copies, separations and colour management remain in VectorCraft; Windows 7 retains WMI and the installed PDF viewer. The print-preview and physical-device fidelity gaps remain, so print scores and hours are unchanged.
   - A PDF, PDF-compatible `.ai` or `.ait` opened from its pages or its editing copy opens with the File Info that its XMP packet and its document information dictionary give: the author, description, keywords, copyright status, notice and URL, and the created and modified dates, the XMP packet's value where both give one; the title is not changed (`crates/pdf/src/tests_file_info.rs`, `crates/engine/src/tests_fileinfo.rs`).
   - Opening a PDF or PDF-compatible `.ai` whose XMP packet nests elements more than 256 deep no longer overflows the stack: File Info leaves the packet out and takes the document information dictionary's values (`crates/pdf/src/tests_file_info.rs`).
