- catalog store: the journal appender is a let-else with an io::Error,
not expect("appender just opened").
- catalog dates: group_label slices with get(), so a non-ASCII key of a
date's length no longer panics mid-character (regression test).
- codecs jpeg_par: rows come from map_while instead of next().unwrap().
- lightcraft-codecs and lightcraft-catalog now #![deny] unwrap/expect/
panic/unimplemented/todo/unreachable (one test let-else uses panic!
instead of unreachable!); clippy.toml as in the steering PR.

Rust 1.99 (stable since 2026-09-28) adds clippy::chunks_exact_to_as_chunks and widens
clippy::question_mark, which failed `cargo xtask ci` on main. Same behaviour: the
remainder that chunks_exact skipped is the remainder as_chunks returns separately.

- Resize modes: long edge, short edge, width, height, W x H (either orientation), megapixels,
percent; "don't enlarge" (default on); ppi written to JFIF density / PNG pHYs / TIFF tags.
- Full-size export of a cropped photo now renders the crop at native resolution (it was
upscaled to the uncropped long edge).
- Formats: Original (file copied byte for byte + XMP sidecar with the edits, named after the
output) and DNG (raw photos re-encoded losslessly, edits in the embedded XMP).
- Export dialog: Resize-to dropdown, values, Don't enlarge, Resolution; DNG/Original hide
pixel options.
- lightcraft-cli render goes through the shared exporter (colour space, metadata, ppi) and
takes any app.export option via --opt KEY=VALUE; MCP export schema lists the new params.
- xtask resolves the workspace root at run time (a moved checkout broke ci).

RenderRequest gains a sample format (OutputDepth: U8 for previews, U16, F32Linear); deep renders
run the per-pixel stage with the exact sRGB curve and return Rendered::deep alongside the 8-bit
image (GPU stays 8-bit: deep exports render on the CPU). Export encodes deep renders: 16-bit PNG and
TIFF, 32-bit float linear TIFF with a linear ICC profile we generate, 10-bit AVIF (YCbCr planes into
ravif). Output sharpening and watermarks work on deep images. ExportOptions.bitDepth with per-format
defaults (TIFF 16-bit, others 8-bit), export dialog bit depth choice (remembered with the last
export), MCP export schema. Tests: a smooth gradient has 1024 levels in a 16-bit TIFF vs 13 in
8-bit, float TIFF decodes to the same light as 16-bit, per-format depth rules, AVIF 10-bit.

The profile encoder packs tags back to back, so the odd-length description of the
"Adobe RGB (1998) compatible" profile misaligned the copyright tag and macOS ImageIO ignored the
profile in PNG iCCP (sips showed none). Tags are re-laid at aligned offsets; already aligned
profiles (sRGB, P3, ProPhoto, Rec. 2020) are byte-identical.

Own T.81 encoder: Annex K tables, JFIF YCbCr 4:4:4/4:2:0 + gray, EXIF/XMP/ICC segments, bands of MCU
rows separated by RSTn so entropy coding runs on all cores. Per-core speed matches jpeg-encoder at 4:4:4
(225 vs 237 ms on 24 MP, single thread); with all cores 24 MP encodes in ~130 ms vs ~500–800 ms
(loaded machine). Output decodes with jpeg-decoder and zune-jpeg (odd sizes tested); same-or-smaller
files at equal/higher PSNR. 4:2:2 keeps jpeg-encoder. Bench: crates/codecs/examples/jpeg_bench.rs.

Property tests (random bytes behind every magic, mutated/truncated files),
corpus tests (corpus/images, pngsuite, raw routing, system ICC profiles),
ignored 24 MP JPEG benchmark, decode_thumbnail_with(min_embedded_edge),
fast deflate levels for PNG/TIFF, README with formats, licences, gaps.

Decoders (JPEG via zune-jpeg + jpeg-decoder for DCT scaling/CMYK, PNG,
TIFF, WebP, GIF, BMP, PSD composite, JPEG XL via jxl-oxide) produce linear
Rgb32f in source primaries with SourceSpace; ICC matrix/TRC applied exactly,
LUT/CMYK profiles through moxcms; to_working() to linear Rec.2020 D65.
Encoders: JPEG, PNG 8/16, TIFF 8/16/32f, lossless WebP, AVIF (native).
