Merge origin/main into #560 (fit_preview / camera-look refactors of #528, #583, #568, #616).
`starting_colour` now tries the per-file camera-JPEG fit (with the camera profile when there is
one) first and uses the spectral-sensitivity matrices only when that fit fails, before the neutral
fallback, so no photo with an accepted JPEG fit changes. Tests pin the order through an injectable
fit; docs, parity, ROADMAP and what's new describe it. RENDER_CACHE_VERSION 37 -> 38.

Fitted with `lightcraft-cli calibrate` to 125 usable ILCE-7CR ARWs (of 131,
September 2025 to September 2026, Standard creative style) and their
in-camera JPEGs; aggregate colour statistics only.
Without it, 8 of the 131 photos fail the fit gates and open with the
neutral matrix (dE76 6-26 against the camera JPEG). On 26 withheld photos
(profile fitted to the other 105) mean dE76 goes 4.07 -> 3.29 and both
withheld rejections are accepted (26.0 -> 6.1, 6.2 -> 5.5); the 24
withheld photos whose own fit was accepted are about unchanged (12
improve, mean 3.06 -> 3.08, worst regression 1.8). With the final profile
all 131 are accepted. The nine public raw.pixls.us ILCE-7CR codings stay
accepted (mean 1.59 -> 1.99).
A corpus test checks the public lossless-L sample's fit keeps exactly the
built-in profile's matrix and table.

Sony's Dynamic Range Optimizer (factory default Auto) brightens the darker
regions of the camera JPEG, not the raw. The tone curve fitted to that JPEG
carried the brightening into the raw's starting look: on 8 ILCE-7CR photos
with DRO on, LightCraft rendered +6.4 L* from Lightroom's default (median
dE76 7.5), against -0.2 L* (3.6) for the 16 with DRO off.
- lightcraft_raw::embedded_preview_dynamic_range_optimized reads Sony
maker-note tag 0xb025 (every documented value: 0 off; 1-3, 8-12 and
16-23, i.e. up to Lv8, on). It was present on all 264 Sony raws checked
(98 bodies); 0xb04f only says on/off and is missing on older bodies.
- With DRO on, the look keeps the colour fitted to the JPEG and its tone
curve is lowered, knot by knot, to Sony's curve without DRO wherever that
is darker (assets/camera-tone/sony-dro-off.json, pooled from 12 CC0
raw.pixls.us ARWs of 10 interchangeable-lens bodies; sources and
derivation in the file and assets/ATTRIBUTION.md). The second-last knot
is lowered only as far as keeps the shoulder past the last knot at or
below the fitted curve, so the result is never brighter anywhere.
Compacts that map raw values darker keep their own curve.
- DRO off, unknown and other makers: unchanged (byte-identical renders on
71 + 35 photos). Render cache version 23.
DRO-on photos now land at +0.8 L* from Lightroom (median dE76 3.3), band by
band like the DRO-off ones. Docs: camera-preview-colour.md, parity row.

A raw without colour matrices of its own now gets DNG ColorMatrix1/2 and
ForwardMatrix1/2 for its model when the model is one of the 52 cameras
in rawtoaces-data (Academy Software Foundation, Apache-2.0): 22 Canon,
11 Nikon, 11 Sony, 3 Fujifilm and 5 others, plus the other names its
alias list gives (Rebel T3i and Kiss X5 for the EOS 600D; bodies it
lists as sharing a sensor). tools/spectral_camera_table.py fits, under
Standard Illuminant A and D65, a white-preserving 3x3 to the measured
spectral sensitivities over rawtoaces-data's 190 training reflectances
and writes crates/raw/src/spectral_table.rs. No number comes from Adobe
or from a raw decoder. lightcraft_raw::spectral looks a camera up by
Exif make and model; the DNG colour model does the rest.
camera_preview::starting_colour takes the first available of: the
file's own matrices, a camera profile for the model (fitted to the
JPEG for tone), the spectral matrices, the file-local JPEG fit, the
neutral fallback. A profiled model whose profile fit fails takes its
spectral matrices. White balance stays relative to the as-shot look for
every raw without matrices of its own, so Photo::relative_wb and the
controls are unchanged; calibrate still pools covered models.
Tests: one per precedence step (synthetic), the table's lookup, aliases
and DNG shape, and a corpus test of the order on ILCE-7M4 (profile),
EOS 5D Mark III and D5100 (spectral), EOS 7D (own fit) and a DNG. The
ILCE-7RM2 and GFX100S corpus tests now expect the spectral matrices.

1.Added Simplified Chinese font support for web and desktop builds.
2.Kept Inter as the default font, with Chinese used only as a fallback.
3.Verified Chinese glyph tests and a macOS universal build.

The DMG opened as a plain Finder window. It now shows the app icon's figure on
the LightCraft colour, with LightCraft.app and the Applications link side by side.
Same approach as VectorCraft's (storytold/vectorcraft#493).
- packaging/macos/dmg/: background.svg (source; text outlined, the figure an
<image> of assets/app-icon), background.tiff (1x + 2x HiDPI, Deflate, sRGB)
and dmg-layout.DS_Store (Finder view settings: window, icon size 128,
positions, background).
- generate.py writes the TIFF and the layout on any OS, byte-for-byte
reproducible, with nothing from the machine that ran it (no paths, users,
disk names or volume UUIDs).
- package.sh copies them into the staging folder; the image is still built with
hdiutil makehybrid. Nothing extra runs in the signing job.
- The volume name drops the version: the layout finds the background through
an alias that includes the volume name. The DMG file name keeps the version.

A built-in Sony ILCE-7M4 colour profile (assets/camera-profiles/ILCE-7M4.json, compact JSON, 39 KB), fitted by lightcraft-cli calibrate to the contributor's own 597 raw photos against their in-camera JPEGs; aggregate colour statistics only, MIT OR Apache-2.0. Compiled in via camera_profiles::BUNDLED; a local profile replaces it.

The Japanese fonts (BIZ UDPGothic Regular/Bold for the UI, BIZ UDMincho for text
watermarks; #110, #114) now come from storytold/craft-fonts instead of assets/fonts/.
- crates/engine/build.rs: the craft-fonts recipe. With CRAFT_FONTS_DIR set it embeds
the manifest's fonts as lightcraft_engine::CRAFT_FONTS (wasm32: BIZ UDPGothic Regular
only, for the web size budget); unset, CRAFT_FONTS is empty. Local files only, no
network; craft-fonts is not in any Cargo.toml.
- UI: theme::font_definitions adds the Japanese faces after Inter and egui's defaults
in every family (BIZ UDPGothic first, Bold first for semibold). About box lists the
embedded families.
- Watermarks: Inter, then the craft-fonts Japanese faces (Mincho first).
- Removed BIZUDPGothic-Regular/Bold.ttf, BIZUDMincho-Regular.ttf and their OFL files,
and their ATTRIBUTION rows; added an attribution row for craft-fonts as an optional
build input; NOTICE updated.
- Tests: Japanese glyph tests use CRAFT_FONTS and skip without it; new tests for
Japanese in the UI with craft-fonts and for the UI and watermarks without it.
- CI: the FreeBSD job builds/tests with craft-fonts. Releases check out craft-fonts at
a pinned commit, build with CRAFT_FONTS_DIR + CRAFT_FONTS_REQUIRED=1, and ship the
fonts' OFL licences (plus NOTICE) in every package.
- Docs: AGENTS.md, CLAUDE.md, README, docs/web.md, docs/localization-ja.md, ROADMAP,
parity.

Shippori Mincho's name table credits 'FONTDASU / Google Inc. / but / Adobe' — its kanji
come from Adobe's Source Han Serif, which our asset rules exclude even under the OFL
(CLAUDE.md: no Source Han fonts). BIZ UDMincho (Morisawa Inc., design TypeBank Co., Ltd.;
OFL-1.1, from google/fonts at 63833b7) is a Mincho of its own with no Adobe glyphs, and
smaller (6.2 MB vs 8.7 MB). Attribution, licence text and NOTICE updated.

Add LICENSE-MIT and LICENSE-APACHE (Copyright (c) 2026 ArtCraft Team and the
LightCraft contributors) and docs/brand/LICENSE-brand.txt from the Crafting Apps
licensing standard. Rewrite NOTICE to the standard template and drop the stale
Source Sans 3 entry (only Inter is bundled). Attribute docs/brand/ in
assets/ATTRIBUTION.md so `cargo xtask assets` passes again. README gets the
standard "License and credits" section; AGENTS.md/CLAUDE.md note the brand
exception to the asset rule.
