A curve rejected for having more than 256 segments now counts the most points a curve may have against the document's pressure points, so linking it from many strokes reads it a bounded number of times. Once the points are used up, later strokes import as plain strokes with a warning.
- Each segment of a pressure curve is also sampled where its width stops
rising or falling, so a dip between the regular samples of a long
curve is kept. The segment's values are scaled into -1..1 before that
is solved, so huge values in a file can't overflow it.
- A curve counts as full width only within 1e-9 of it, so a curve just
under full width keeps its profile.
- The pressure points of all strokes in one read are limited to about a
million, as for characters and table cells. Curves at full width count
too, and once the limit is reached no more curves are read; the
strokes past it are imported as plain strokes with a warning.
An Affinity stroke shaped with the Width tool stores its pressure curve
(LDeP: position along the path against width). The importer warned and
drew the stroke at full width all along.
- The pressure curve is read and sampled into the stroke's width
profile (2 to 8 points per segment, 256 segments at most, widths up
to the full weight). A curve at full width all along stays a plain
stroke; one that can't be read is warned about.
- Brush strokes keep their own warning.
- The pinned Affinity 3 signatures for the five corpus files with such
strokes are updated.
In Affinity Designer, Recolor Adjustment layers (RcRA) can be attached to
vector groups/shapes via AdCh. Lightness 1.0 recolors target elements to
white. Import visible RcRA layers as ColorOverlay effects and apply them
during node appearance evaluation.
A line style's `Patn` was copied twice (filtered, then scaled) whatever its
length, before any budget saw it. Patterns longer than 64 lengths now import
as solid lines, with a warning.
Addresses CodeRabbit's third review on #3548.

- Strokes set to None no longer import as black 1px strokes.
- Underline and strikethrough are kept.
- Frame text starts at cap height; lines hanging out of a frame make it taller;
mixed-alignment artistic text lines up within its longest line; line breaks
inside a paragraph get no paragraph spacing.
- Table cell text taller than its cell is centred and stays visible.
- Outline effects on stroked shapes are drawn around the stroke.
- CMYK pixel layers go through the document's embedded CMYK profile; without
one, opaque layers stay CMYK.

Clippy 1.99.0 added `chunks_exact_to_as_chunks`, which fails `cargo xtask ci`
at its clippy step. Eight uses of `chunks_exact(_mut)` with a constant size now
use `as_chunks(_mut)` (stable since 1.88, within the 1.95 minimum): four in
crates/affinity, three in crates/effects and crates/engine tests, and two in
xtask's sha256. docs/development.md says the gate targets the current stable.

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.
