Visualize Spots, Point Color range and Visualize HDR are drawn on the
loupe's 1:1-8:1 window like mask overlays: the range and HDR views act
per pixel, the spots high pass reads within the window's margin. New
pipeline test: each overlay's window equals the whole-frame render's
pixels. The GPU finish kernel now soft-proofs output-space proofs
(destination and display gamut warnings) like the CPU; an output-device
profile's table still renders on the CPU. New GPU equivalence test.

Nikon bodies from before ~2016 record no CropArea, so the decoder kept
their whole sensor data, less trailing dark columns. Where that data
holds masked lines above black or optical black, they were developed as
a coloured or dark bar on that edge: the D7000 and D5100's 36 columns at
~600 (#976), the D800's 14 (#914, the top in portrait), and others.
MEASURED_BODIES (crates/raw/src/vendor/nef.rs) now gives 36 model /
data size / depth groups the frame of their camera JPEG inside the data:
D7000, D5100, D800, D800E, Df, the D4's 12-bit mode, D3, D3S, D700,
D300, D300S, D600, D610, D810, D4S, D5600, Coolpix A, D3000, D40X, D60,
D80 and D2Xs. An entry matches model, data size and depth exactly; the
measured white level becomes optional (only the D4's 14-bit mode has
one). Bodies whose data holds only picture beyond the camera frame get
no entry and render as before.
`cargo xtask raw-frame FILE...` (crates/engine/examples/raw_frame.rs)
measures a body: it aligns each raw's embedded camera JPEG with the
sensor data (half-size luminance, gradient correlation, sub-pixel peak;
weak, ambiguous or between-pixel peaks are flagged), counts the edge
lines that hold no picture and reports what the decoder's crop keeps
beyond the camera frame. It prints entries only with evidence: at least
3 clean files agreeing exactly, of the model (12- and 14-bit pooled) or,
with at least one of its own, with sibling models of the same readout
(data and JPEG size) that agree on the same frame. On the D7500, which
records its CropArea, it finds that area exactly; it declines the Z f,
whose JPEG is distortion-corrected.
It works for any make whose raw embeds a full-size camera JPEG: on
Sony, Canon CR2 / CR3, Pentax and Samsung files it finds the decoder's
own crop (relative to the active area).
docs/nikon-bodies.md surveys every Nikon raw on raw.pixls.us (98
models, 291 files; 138 CC0 samples measured): 22 models record
CropArea; of the 88 groups without it, 36 have entries, 13 are fine, 25
could not be aligned and 7 do not decode. The D3200, D3100, D200, D50,
D750 and Nikon 1 V1 / V2 are pending, each listed with the files it
needs; the doc also describes how to add a body. raw-parity.md no
longer claims every NEF coding but HE decodes.
measured_bodies_are_consistent checks every entry lies inside its data
and is listed once.
The evidence is committed in docs/nikon-bodies/: headers.json (every
file's raw size, depth and maker-note crop tags), samples.json (the 138
measured CC0 files with URL and sha256) and frames.jsonl (the tool's
per-file results). `cargo xtask corpus --download nikon` fetches the
samples (sha256 checked) so `cargo xtask raw-frame` reproduces every
count.

While no monitor profile is chosen, the Linux app reads the profile the
desktop assigns to the display in colord (org.freedesktop.ColorManager,
system bus, via zbus) on a background thread every 3 s, and shows
previews through it. With several displays it is used only when they all
share one profile; without colord the view stays sRGB. Windows' WCS
needs FFI and stays manual. Also satisfies clippy 1.99's
chunks_exact_to_as_chunks in spots.rs.

New export format `rendereddng` (export dialog: Format DNG, "DNG of: Rendered
photo"; `app.export`; MCP export tool): the rendered photo, with the edit,
crop, size, output sharpening and watermark baked in, written by the new
`lightcraft_raw::write_rendered_dng` as a LinearRaw DNG of 16-bit float Deflate
tiles in the export colour space. ColorMatrix1 (XYZ -> space), ForwardMatrix1
(space -> XYZ D50), a neutral AsShotNeutral and an identity ProfileToneCurve
make raw converters show it as rendered. HDR edits keep highlights above white.
Bad input (wrong sample count, zero or huge sizes, NaN/inf, out of half-float
range) gives an error or is clamped, never a panic.
Also fixes the Rust 1.99 clippy lint chunks_exact_to_as_chunks in
pipeline/spots.rs that fails `cargo xtask ci` on main.

One CC0 raw.pixls.us file per Nikon and Fujifilm body that decodes is
added to RAW_SAMPLES and pinned in crates/raw/tests/body_corpus.rs: own

The sweep found COOLPIX 5700 / 8400 / 8800 decoding wrongly (two stacked

spot targets and sources plus a New spot point (Return adds), radial and
linear gradient handles and mask pins. Arrows move by 0.5% (Shift 5%),
one undo step per press; the stand-in keeps arrows/Return/Space from the

Brush strokes record a pen pressure (0..1) per point from egui touch
force while Brush > Pen Pressure is on (default). Each dab's radius goes
from a tenth to all of the brush, and its flow is proportional to the
pressure, in the committed stroke and the live preview alike. A mouse
stroke stores no pressure, so documents and renders are unchanged. The
GPU mask kernel leaves pressure strokes to the CPU. mask.brushStroke takes
`pressure`; bad lists are refused. Also satisfies clippy 1.99's
chunks_exact_to_as_chunks in spots.rs.

Soft proof is per-pixel, so the After window carries the proof like the
whole-frame render under it (the proof key is part of the tile's look).
New tests: a 1:1 window of a 24 MP photo equals the full-size export to

native window. profile_slider_drag gains a soft-proof case. Gap 4 closed,

Preserve page-backed large-catalog import while integrating upstream catalog and documentation changes. Adapt only the sparse test fixture to the shared upstream fixture helper.
Use the equivalent complete RGB-triple iterator required by Rust 1.99 Clippy; the same lint failure was reproduced on the exact upstream baseline.
Validation: 47 catalog tests, nine spot tests, exact sparse regression, all eight CI gates, and an original synthetic headless import/selection check passed.
Generated with Codex.
DNG export gains a "Lossy" compression: the raw data is demosaiced to linear
camera RGB (OpcodeList3 and the default crop applied), scaled to the resize long
edge when one is set, and stored as 8-bit baseline JPEG tiles at the export
quality. The codes follow a 1/2.2 power curve that a LinearizationTable maps
back to linear 16-bit values; colour matrices, white balance and the profile
look are kept. Available in the export dialog, `app.export`
(`dngCompression: "lossy"`) and the MCP export tool.
Also fixes a new clippy lint (chunks_exact_to_as_chunks) in pipeline/spots.rs
that fails `cargo xtask ci` on Rust 1.99.

All 38 files decode from sensor data and develop at full size (9520x6336 and
6336x9520) without error; mean CIE76 dE to the camera JPEG is 6.3-13.9 at 400 px.
The files are not committed and the evidence entry carries no path. Leica is now
14 verified / 47 unverified, the Leica bucket on a verified body 5% -> 21%; the
weighted shares (85% decode, 42% on a verified body) do not move.

A raw shot in a monochrome picture style records full colour, but its
camera JPEG is grey: neither the full look nor the partial look has
colour to fit, so the photo started from the spectral matrices or the
neutral fallback with the default tone curve, about 1.3 EV darker than
the same body's colour-shot photos. The grey JPEG still shows the
camera's tone curve.
When no look was fitted and the JPEG is black and white (`monochrome`),
fit the quantile tone curve alone on top of the colour the photo gets
otherwise: the camera profile's (in `fit_preview`), else the spectral
matrices or the fallback (`monochrome_look`, after the spectral step).
The chroma curve stays neutral; the partial look's checks apply. A
tone-only look keeps the file's colour model for white balance.
LOOK_VERSION 2 -> 3, RENDER_CACHE_VERSION 42 -> 43.

The CRX 0x200 QP map opens with its first symbol as a 32-bit literal; every
later symbol is Rice coded with a limited-length escape: 23 zeros, the
terminating 1 and the symbol in 8 bits (the ITU-T T.87 layout for a 32-bit
limit and 8-bit symbols, without its minus-one offset). The old rule (an
escape after 16 zeros with a 16-bit literal) matched only the first symbol,
which is all the R8 and R7 maps need. R5 Mark II maps (QP 150-162) jump by up
to 12 where the Rice parameter is 0, giving 18- to 22-zero prefixes that
misparsed ("Canon CRX adaptive QP value -21087"): 174 of 306 sampled files
from a private R5 Mark II library opened as previews. Every QP map of its
33,665 C-RAW files now decodes to the exact end of its entropy stream; the six
oracle fixtures are unchanged. Established by black-box analysis of the
bitstream; no third-party decoder source consulted.

Compare and Reference drew each pane from a whole-frame render of at most
2560 px, so 1:1 was a magnified preview and focus could not be checked.
Each pane now also renders the window on screen from the photo's own
pixels (Slot::CompareRegion), as the loupe does (#323). The media cache
keeps up to two full-size originals while either view is open, so one
pane's window does not evict the other's source.
