handles the eyedropper (crosshair cursor, click samples, shift-click adds)
through a shared color_range_pick helper.

On some Windows machines FXC fails to compile egui's own shaders on DX12
("The parameter is incorrect. (0x80070057)" in egui_pipeline) and wgpu's
default error handler panicked. Each renderer (DX12, Vulkan, GL, glow) is
now probed with error scopes and a logging error handler before the window
opens; the one that works is remembered; a start that dies leaves a marker
and relaunches with the next renderer. LIGHTCRAFT_GPU_BACKEND=glow added.

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.

export_progress_and_cancel failed every time on a fast machine (M5 Max, 4
export lanes): the 8 demo photos exported within the 100 ms progress
throttle, so the first progress above 0 was the final 8/8 and the cancel
arrived after the export had finished (a reply to the cancelled request,
or all 8 files on disk).
The test now wraps Headless in a test-only backend that, at the first
photo boundary, keeps polling the server's real progress hook (which
answers pings and reads cancels) until the cancel is read or the test
releases it, bounded at 20 s so a broken cancel fails rather than hangs.
The first export is released once the mid-batch ping is answered (that
was the same race), the second only ends by the cancel. That makes the
outcome exact, so the check tightens from "1..7 files" to "exactly the
one completed photo", which also proves the photos the other lanes had
already rendered are never written. No production code changes.

Soft Proofing's Profile menu takes a printer / paper ICC profile (Other…;
`view.softProof {profile, intent, paperInk}`), RGB or CMYK, matrix or LUT.
The CMS (moxcms) builds a 33^3 proof table over the working space: forward with
the chosen intent (Perceptual / Relative), back relative colorimetric; the
destination gamut warning comes from the colorimetric round trip. Simulate
Paper & Ink renders absolute colorimetric: the profile's media white replaces
screen white and the ink black is unscaled. The pipeline gets the table by id
(`Proof::profile`, `register_proof_profile`), so Proof stays Copy and render
keys include it. Proof copies are named after the profile.

New `inpaint` crate (L1): multi-scale patch-based completion with a PatchMatch
nearest-neighbour field, seeded by a membrane fill. Deterministic, no panics on
hostile sizes, cancellable. Ported from PhotoCraft (MIT OR Apache-2.0).
Remove tool: a fourth spot mode, `fill` ("Content-Aware"), rebuilds the spot
from patches of its surroundings instead of one source; coarse-to-fine, so the
structure is chosen at a scale set by the spot size and preview and export agree
(tested). spot.add leaves its source unset.

HsvTable::apply took the value through linear -> sRGB -> linear even when the table's value
scale is 1 (every hue/saturation-only table, as fitted camera looks are), and wrapped hues with
rem_euclid (an fmodf call) three times per pixel. The value is now kept as it is for a unit
scale and the sRGB-encoded value is reused otherwise; hues are wrapped by a helper that equals
rem_euclid bit for bit (tested) without the call for values within one period.

library.buildPreviews rendered one photo at a time, and each photo's thumbnail job decoded the
file again at thumbnail level after (before, in fact) the view job had decoded it at preview
level. Now the view renders first and its decoded source serves the thumbnail, and photos
render in as many lanes as an export batch (two for 1:1 previews, a full-size source each);
a panic in one photo counts as that photo's failure.

A noise-reduction change invalidated the scene-linear stage and with it every spatial
plane (base, clarity, dehaze, chromaticity), so each tick of an NR drag on the CPU rebuilt
all of them. The plan now also carries the linear key without the NR settings; a draft
render whose image differs from the cached one only in NR keeps those wide blurs and redoes
only log luminance and the fine texture band. Full-quality renders never take them.
Draft NR drag, single thread: prepare 18.7 -> 7 ms (render ~135 -> ~125 ms CPU).

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

Open Library given a Lightroom Classic catalog folder, one of its .lrdata /
.lrcat-data folders, Backups/, the .lrcat or its -wal/-shm/.lock files used to
create an empty LightCraft library inside Lightroom's folder (or, for the
.lrcat file, close the current library and then fail). Now:
- engine: lightroom_folder::lightroom_catalog_at (names only, top-level scan
bounded to 10 000 entries, never fails); Session::open_library refuses those
places with EngineError::LightroomCatalog {path, catalog} before creating
anything. A LightCraft library (catalog.snap / catalog.log) always wins.
- app: app.openLibrary checks before closing the current library, keeps it,
returns {opened: false, lightroomCatalog, path} and shows a dialog with
Import Lightroom Catalog… (file.importLightroom with the catalog found) and
Cancel. The library problem window gets the error instead.
- Lightroom import status keeps the catalog path after the task ends.
- CLI --library explains how to import instead.
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.

With HDR output on, a photo edited in HDR exports as a 16-bit PNG with the PQ
curve in Rec. 2020 (SDR white at HDR_REFERENCE_WHITE_NITS), described by a
`cICP` chunk (PNG third edition: BT.2020 primaries, PQ, RGB, full range) and
a `cLLI` content light level chunk (the levels the HDR AVIF records). EXIF,
XMP and print resolution are kept; no ICC profile next to cICP. Photos without
an HDR edit, and HDR edits with HDR output off, export as before.
`codecs::encode_png_pq` sits next to `encode_avif_pq` and takes the same
input. Follow-up to #646, ported from #466.

storytold/craftrules is not a public repository, so the standards link in the
Chinese/Japanese fonts note was a 404 for anyone outside the maintainers. The
rule the sentence states lives with the font repo it points at anyway.
Raws with a fitted camera look (e.g. Nikon NEF) rendered HDR with the
generic tone curve instead, more than a stop darker through the midtones
than the SDR render: PQ JPEG XL / AVIF exports looked dark everywhere,
and gain map JPEGs carried negative gains, so they went dark on HDR
displays. ToneMap::camera_hdr keeps the camera curve up to 1.5 EV over
grey and lifts highlights as ToneMap::hdr does.

HueSat::apply restores luminance with before / after. Near black, where noise makes some channels
negative, the hue/saturation table can bring after close to 0, and the gain turned single pixels
white (isolated white dots in dark areas, most visible at fit). Luminance is now restored only if
the table kept at least 25 % of it; such colours keep their colour, like black and non-finite ones.

The preview was capped at 348 × 200 pt, so a portrait photo showed about
130 pt wide. It now spans the dialog for any photo shape. The cached 512 px
thumbnail still shows at once; a render at the preview's own pixel size
(in 128 px steps) then replaces it, so the wider preview stays sharp. The
web build, which has no worker thread, keeps the thumbnail only.
