- 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.
