Saving (Cmd+S or auto-write) now merges LightCraft's properties into an
existing sidecar (lightcraft_meta::merge_xmp): owned properties (rating,
label, dc/IPTC/rights fields, lc:*) are replaced or removed, capture time
and GPS only when LightCraft has a value; everything else (crs:,
xmpMM:History, unknown namespaces, packet wrapper) is kept byte for byte.
The result is re-parsed and checked before it is written (temp + fsync +
rename). A sidecar that isn't valid XMP is copied to .xmp.bak-<time>
(never overwriting) before it is replaced; one that can't be read at all
is left alone and the save fails.
Shared stems: when several catalogued files map to one stem sidecar
(IMG.CR3 + IMG.JPG), it belongs to the raw (else the first by name) and
the others write and read <file>.xmp.

Catalog Meta gets copyright_status (unknown / copyrighted / publicDomain), usage_terms and
copyright_url, read and written as XMP Rights Management fields (xmpRights:Marked, UsageTerms,
WebStatement) on import, sidecars and exports (kept by "copyright only"). photo.setMeta,
copy/paste metadata, metadata presets, a Copyright Status smart-album rule and the Info panel.

A sidecar's exif:DateTimeOriginal / photoshop:DateCreated / xmp:CreateDate
now reaches Photo.captured on import and on Read Metadata from File when
the file has no embedded capture time (embedded wins). On import the
sidecar is read before copying, so the date also files and names copies.

An .lmp look is an XML property list of adjustment layers with named
sliders (newer looks: a Name.lmp/Contents/preset.lmp bundle); an
.mplumpack is a zip of looks plus PresetsInfo.plist (GroupName).
preset.import, the file dialog and drag & drop now accept both. Sliders
with a clear counterpart (exposure, contrast, highlights/shadows,
whites/blacks, WB shift, saturation/vibrance, clarity/structure,
dehaze, HSL, point curves, vignette, grain) map onto develop settings;
the rest is reported in `unmapped`. Looks are named after the look and
grouped by the pack. Tests use synthetic looks and packs only.

lightcraft-pipeline gains lut.rs: a .cube parser (LUT_3D_SIZE, DOMAIN_MIN/MAX, TITLE), a
trilinear lookup and an in-process registry; the finishing stage applies a `lut:` profile to
the display-encoded colour, blended by the profile amount (0–200 %); LUT profiles render on the
CPU. profile.import {paths} reads files, folders and zips, copies each LUT into the library's
Profiles/ folder, lists them in prefs and registers them when the library opens; the profile
browser shows them under their folder / zip name; profile.deleteImported. File ▸ Import
Profiles & Presets…, the file picker and drag & drop take .cube files.

Local corrections stored as crs: structures (MaskGroupBasedCorrections and the older
gradient / circular gradient / paint containers) become our masks: linear and radial
gradients, brushes (dab runs → strokes), Subject / Sky, luminance and depth ranges, with
add / subtract / intersect and invert, and all local sliders. lightcraft-meta's XmpData gains
`values`, a structured view of every property (arrays of structs survive); .lrtemplate Lua
tables convert into the same shape.
Applying a preset adds its masks to the photo's own (once; Amount scales them); sidecar masks
replace them and radial masks are fitted to the photo's aspect. Unsupported components
(colour range, other AI selections) are reported as "Mask: <kind>".

preset.import (File ▸ Import Presets…, Presets panel ⋯, drag & drop, CLI, MCP) now reads
everything people actually download or carry over from other editors:
- classic .lrtemplate files (Lua table literal parser; value.settings uses crs: field names),
including old process-version fields (Exposure, Contrast, FillLight, HighlightRecovery,
Shadows, Brightness, Clarity, ToneCurve) approximated with today's sliders;
- photos carrying their edits in XMP ("DNG presets" from mobile apps, edited JPEG/TIFF): the
look only, without the photo's crop, geometry or custom white balance;
- .zip bundles (stored + deflate) of any of these, skipping __MACOSX / hidden files;
- folders: the pack's folder name becomes the group, skipping app/format container folders
("Lightroom Classic", "XMP", "Mobile (DNG)"…).
Each imported preset reports the settings that had no counterpart (`unmapped`: profiles,
looks, local masks); the app's toast names them. dryRun previews, group overrides.
Dropped .lcpreset/.lrtemplate/.xmp/.zip files import as presets instead of photos.

curve.refineSaturation (0..100, default 100 = the curve's own saturation): after the tone
curves, the chroma around luma is rescaled so saturation moves from the curve's towards the
pre-curve value, keeping the curve's tone. CPU (finish::refine_saturation) and GPU twin,
equivalence case, slider under the curve editor, crs:CurveRefineSaturation import.

White-preserving primaries matrix (OkLCh hue rotation / chroma scale of each Rec.2020
primary) plus a luminance-preserving green/magenta shadows tint, applied in scene-linear
light before the tone map. CPU (colorops::calibrate) and GPU (finish.wgsl) with an
equivalence case; seven control specs (calibration.*), a settings group, crs: import
(ShadowTint, Red/Green/BlueHue/Saturation) and a Calibration section at the bottom of the
Edit panel.
