Load PDF document objects through the pinned craft-pdf parser and convert them into EffectCraft's existing drawing model with bounded traversal, recovery and retained data. Preserve generation numbers, stream limits, encrypted-document refusal and reported repairs.
Retain app-owned drawing, EPS, fonts and content/image decoding. Assert early excessive-nesting rejection without partial art, and cover tolerant arrays on native and WASM.
Validated with the22-stage local matrix and exact-head FreeBSD, Windows ARM64 and packaging checks.

The PDF / Illustrator import dialog now offers Composition - Retain Layer
Sizes. Each file layer's footage is cropped to its artwork bounds (fills,
stroke outlines, images, clips) and positioned to keep its place on the
page. Decoding, continuous rasterisation, shape conversion and reload share
one crop (effectcraft_pdf::layer_doc_with_sizes), so they agree.
Also collapses a match guard in the STL reader for current stable clippy.

A PDF could abort the process through its colour spaces and functions.
An Indexed hival of 10^12 asked an image for a 24 TB palette. A sampled
function's outputs (one per /Range pair) multiplied its table without a
bound, and copies of the table (one per q, one per reference) multiplied
it again. Self-referencing colour spaces and functions overflowed the
stack, a calculator's copy doubled its operand stack, index, idiv and
mod could panic, and f64::clamp panicked on a reversed /Domain or
/Range. Clamp hival to 255, count samples with checked arithmetic (at
most 32 inputs and outputs, 2^24 samples a table), share the samples,
give one function read a budget of nodes and samples, limit nesting to
8 levels and the calculator stack to 100, and clamp with the bounds in
either order.

decode_stream_within now bounds the output of each stage of a /Filter
chain, not only FlateDecode. RunLength, LZW, ASCIIHex and ASCII85 stop
when their output would pass the limit, a full LZW table takes no more
entries, PNG predictor rows are sized with checked arithmetic and only
allocated when a whole row fits in the data, and CCITT checks
/Rows x row bytes against the limit before allocating.

inflate used the unbounded miniz_oxide functions, and File::parse decodes
every object stream eagerly. Use the limit variants (1 GiB per stream, 256 MiB
for object streams, a quarter of that on 32-bit targets) and bound the
truncated-stream salvage buffer too.

Text with embedded TrueType, CFF (Type1C / CIDFontType0C / OpenType), Type 1 and Type 3 fonts,
standard-14 fallback to the bundled OFL fonts; Flate / DCT / inline / stencil images with SMask,
Indexed and ICC alternates; luminosity / alpha soft masks and the 16 blend modes in the SVG
render tree; tiling patterns; calculator functions; file.import page and Footage::page;
Create Shapes from Vector Layer keeps clips (page clips as layer masks, nested clips as Merge
Paths Intersect).
