On merge: Lightroom's default profiles (Adobe Standard, Adobe Color), named by nearly every sidecar,
give no camera-profile warning; other profiles still do (test default_lightroom_profiles_are_not_reported).
The import help string keeps main's onDeleted wording and gains warnings.
Lightroom's Light panel "HDR" switch (`crs:HDREditMode`, `1`/`True` on,
`0`/`False` off) now sets `hdr.enabled` when importing XMP sidecars, presets,
DNG presets and Lightroom catalogs, instead of being reported as unmapped (an
off value was already silent). The rest of the HDR settings keep their
defaults. Follow-up to #646, ported from #466.

Raws without matrices in the file (ARW, NEF, RW2, RAF, CR2, CR3, PEF, SRW,
ORF) were all edited on the relative white-balance scale (6500 K / 0 = as
shot), even when lightcraft_raw::spectral has measured matrices for the
camera. Those 52 bodies (ILCE-7M3, ILCE-7M4, D850, EOS 5D Mark III...) now
edit in Kelvin like a DNG and like Lightroom.
Design:
- One decision on both sides: spectral::find_camera("Make Model") backs
catalog::relative_wb_camera (Photo::relative_wb); files::WbScaleOf decides
the same from the decoded file. A corpus test asserts they agree.
Photo::fitted_look keeps the old predicate for smart previews.
- The matrices only convert: As Shot is the file's multipliers read through
the model's ColorMatrix1/2 (spectral::as_shot_white_through). The look
(JPEG fit / profile / spectral fallback) is unchanged, and the slider
adapts from that white with Bradford. The camera-space rebalance stays
reserved for files with their own matrices.
- Presets resolve to their Kelvin values (WbMode::preset, sources cited).
- The Color panel shows the white balance in effect (effective_wb).
- XMP: crs::Target::for_file takes the camera; matrix cameras read
crs:Temperature as Kelvin (marked "scale": "kelvin"), others keep the
#510 as-shot shift.
Migration (no look changes):
- WhiteBalance.scale: WbScale { Legacy (absent in JSON), Kelvin }. A
white balance without a scale keeps its old meaning. On a spectral-Kelvin
raw (SourceInfo.legacy_relative_wb) the pipeline composes the old
adaptation (6500 -> value) with the new one (as shot -> ...) in Bradford
cone space (local::legacy_white). Von Kries scalings compose exactly, so
the matrix matches to f32 and the pixels are identical
(pipeline legacy_relative_white_balance_renders_as_before_on_a_kelvin_raw,
media old_relative_white_balance_on_a_kelvin_camera_keeps_its_look...).
- Every white-balance writer (develop.set/adjust/quickAdjust/wb/wbPick/
reset) first runs local::normalize_wb: a legacy value becomes the Custom
Kelvin value with the same look and is marked Kelvin. Partials without a
scale (old presets, develop.merge) stay legacy.
- Catalog format 7: Op::SetAsShotWb replaces the 6500/0 as-shot recorded
by older imports when the file is next decoded or reloaded (system op,
not an undo step). Format-version test updated.
- The web wire carries legacy_relative_wb.
Docs: parity (LR-EDIT-COLOR-TEMP), camera-preview-colour, xmp-interop,
lightroom-catalog-import, control-protocol, mcp, whats-new.
Heal and clone spots stored as crs:RetouchAreas (Mask/Ellipse, Mask/CircularGradient
or a brushed Mask/Paint target; SourceX/OffsetY as the source's absolute position,
honoured only when the source was set explicitly; Opacity and Feather 0..1) and the
legacy crs:RetouchInfo list become our spots when a sidecar, embedded XMP, XMP preset
or .lrtemplate is read. Width fractions are converted to long-edge fractions with the
target's aspect, like radial masks. Unsupported spot masks are reported as
`Spot: <kind>`. Format established by observing what a sidecar written for a healed
photo contains; clean-room.
Tests: heal with explicit source, clone with automatic source, brushed removal,
circular-gradient spot, unsupported mask reported, portrait-target scaling, legacy list
on its own, and a render test. docs/xmp-interop.md gains a Spot removal section;
LR-META-XMP row updated.

Lightroom Classic 15.6 imports an XMP packet's channel curves only when it holds
ToneCurvePV2012 and all three of ToneCurvePV2012Red/Green/Blue; any partial set
(master + one or two channels, channels without the master) imports without
channel curves. #416 read them whenever the master curve was present.

A Custom white balance from a Lightroom catalog or XMP sidecar was taken as absolute Kelvin for every
raw. Raws LightCraft develops relative to their as-shot look (ARW, NEF, RW2, RAF, CR3, CR2, PEF; 6500 K
means as shot) then read a small tweak as a large blue shift: ΔE 22 against Lightroom's export on the
photos of issue #510.
The crs mapper now takes a `Target` (preset, rendered, raw with a measured illuminant, relative-WB raw)
instead of a bool. For relative-WB raws, and rendered files with only `Temperature`, a Kelvin value is
converted to the same mired shift from the packet's `AsShotTemperature` / `AsShotTint`. Without that
reference (Lightroom catalogs keep none for Custom photos) the photo stays As Shot and the import
report lists `Temperature, Tint` as not carried over. Import, sidecar read and catalog import decide
the target the same way through `lightcraft_catalog::relative_wb_format`.
Tests: shift from the issue's numbers (3650 → 3578 K lands at ~6275 K), the As Shot fallback with its
report entry, target selection per file, and the catalog mapper's Custom-WB case.
Lightroom Classic reads `ToneCurvePV2012Red/Green/Blue` only together with
`ToneCurvePV2012`: a packet with a channel curve and no master curve leaves the
photo unchanged there (rendered on a chart: the channel curve alone has no
effect, with an identity master curve it applies). Imports now do the same.
The preset-packet test helper uses made-up as-shot values.

XMP presets usually say LensProfileEnable=0, which turned optics.lens_profile
off and with it the DNG-embedded WarpRectilinear / FixVignetteRadial
corrections (iPhone ProRAW and other files that carry them). Lightroom
applies a file's built-in corrections whatever that switch says (our
inference), and LightCraft's profile corrections are only those embedded
ones, so crs import now carries over only an enabling switch. The Enable
Lens Corrections checkbox and the amount sliders keep working as before.

XMP presets carry fields that describe the preset or the photo rather than
an adjustment (Cluster, SupportsAmount2, RequiresRGBTables, SortName,
Description, CropConstrainToWarp, OverrideLookVignette, AsShotTemperature /
AsShotTint). preset.import listed them as settings that couldn't be carried
over; so did an HDREditMode of 0 and PointColors slots that are all -1.
They are now treated as bookkeeping; an HDR edit, a used Point Color slot and
unknown adjustments are still reported.

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.
