LightCraft's RPM requires Fedora package names: `libxkbcommon`, `(vulkan-loader or libglvnd-egl)`.
openSUSE has no `libxkbcommon`, `vulkan-loader` or `libglvnd-egl` package, so zypper refuses it with
`nothing provides 'libxkbcommon'` (exit 4, which the ArtCraft Launcher shows as "error 4";
storytold/craft-launcher#341).

Detect ../craft-fonts or use CRAFT_FONTS_DIR on macOS, Linux and Windows.
Download the pinned release revision when the checkout is missing
and require Chinese and Japanese fonts during the build.
Document font setup and preserve skip-build behavior.
- release.yml: new linux-riscv64 job (ported from GridCraft): cross-compiles on
ubuntu-24.04 against ports.ubuntu.com riscv64 libs, packages a tar.gz with
package.sh --formats tar, smoke-tests lightcraft-cli under QEMU. The release
job needs it, so its tarball lands in the draft and SHA256SUMS.
- packaging/linux/package.sh: CROSS_ARCH/CROSS_TARGET/CROSS_COMPILE/EMULATOR
support (target dir, cross strip, emulated --version).
- README Downloads and docs/releasing.md list the riscv64 tarball.

heic-rs reconstructs iPhone HEVC tiles bit-exactly (checked against libde265), but
its colour stage was 2-27 code values off libheif on every iPhone photo: it ignores
the HEVC VUI and assumes BT.709 limited range. lightcraft-heif now converts YCbCr
itself (nclx, else VUI, else H.265 defaults; nearest chroma, bilinear for odd clap
offsets, as libheif), inherits tile ICC/nclx on grids, follows libheif's imir axis
and clap rounding, and outputs 16-bit RGB. Measured on 30 real and synthetic
files: within 1 code value of libheif (pillow-heif 1.8 / libheif 1.23).
Also: HEIF header reader for import (no pixel decode), embedded thumbnail for small
decodes, nclx/VUI colour hint (shared CICP mapping with PNG), clear 4:2:2/4:4:4
Unsupported error, Format::not_decodable as the one source of "why not" (import
reports "HEIC/HEIF support isn't included in this build"), `.heif` imports.
Release packaging and Nix build with the heif feature, as whats-new promised.
lightcraft_heif::testdata writes lossless (PCM) synthetic HEICs for the tests.

* Release: FreeBSD x86_64, Flatpak x86_64/aarch64, AppImage zsync updates; README Downloads
- linux: appimagetool -u embeds gh-releases-zsync update information; the .AppImage.zsync is
published beside each AppImage (zsync installed; checked in the job).
- flatpak: new job per arch repackages the Linux tarball into a single-file .flatpak
(packaging/linux/flatpak-bundle.sh + ai.storyteller.lightcraft.bundle.yml); the Flathub
manifest gets the CLI and the same commented finish-args; packaging-lint checks they agree.
- freebsd: new job builds lightcraft-<ver>-freebsd-x86_64.tar.gz in a FreeBSD 14.3 VM with the
freebsd.yml packages (packaging/freebsd/package.sh; layout dry run in packaging-lint).
- version, linux and web no longer use the release environment (they sign nothing), so a
branch dispatch dry-runs every unsigned job; the release job still needs macOS and Windows.
- README: Downloads section listing every build; docs/releasing.md updated.

Decode every raw encoding Panasonic and Leica bodies write, from the DMC-LX1 (2005) to the DC-S1RM2 (2025):
compressed formats 4 (most bodies, 2008-2022) and 6 (S1 / S1R / S1H / S5, GH5M2), the prefix-coded strips of
format 8 (GH6 and later), packed formats 2, 5 and 7, and the 16-bit words of the 2005-2007 .RAW files. Until now
only format 5 decoded; every other Panasonic file opened as preview only.
Clean-room: no raw-decoder source was read. Tag names come from tag documentation; every encoding was recovered
by black-box analysis of 178 CC0 files from raw.pixls.us (118 bodies), and the module docs note the measurement
that settled each rule. Format-8 tags of unknown meaning must carry the values every sample has, otherwise the file
is reported as unsupported rather than guessed at.
Levels and geometry: formats 4 and 6 store samples 15 above the recorded black level (files without one use 15);
white is the active area's saturation plateau (the linearity limits are wrong on extended low-ISO shots, the GF1
and the Digilux 3); the in-camera aspect ratio is the default crop; mapped-out defect pixels are filled from
same-colour neighbours; the CFA pattern applies at sample (0, 0).
.rwl and .raw files are imported (engine, MCP folder expansion, file dialog, Linux MIME types). One file per
encoding joins the never-panic proptest; 11 CC0 files join `cargo xtask corpus`, and corpus_panasonic_encodings
checks each encoding's bit depth, black level, crop and CFA layout against the camera's own JPEG.
