Adds Georgian (ქართული, code ka, system tags ka / ka-GE / ka_GE) with
complete plain and formats catalogs, the Edit > Language command and the
Settings choice. Sentence-cased messages go through i18n::upper_first,
which leaves Georgian letters alone (upper-casing Mkhedruli would turn it
into Mtavruli). The Settings language choices wrap now that eleven
endonyms no longer fit on one line, and the face-model Remove button goes
through tr().

Fitted with `lightcraft-cli calibrate` to 144 usable ILCA-99M2 ARWs (of
150, seven shooting days, Standard creative style, DRO Auto) and their
in-camera JPEGs; aggregate colour statistics only.
On 30 withheld photos (profile fitted to the other 120) mean dE76 against
the camera JPEG goes 5.11 -> 4.87; 25 of 30 improve, the worst
regression is 0.24. All 150 photos stay accepted. The public raw.pixls.us
ILCA-99M2 file, not used for fitting, stays accepted (5.57 -> 5.73).
A corpus test checks that this public sample's fit keeps exactly the
built-in profile's matrix and table; the ILCE-7CR test now shares its
body. LOOK_VERSION 5 -> 6, as the profile changes the fit of this model.
Conflict in panels/dialogs.rs: keep upstream's PQ/HLG HDR curve choice
and route both labels through i18n::tr. Czech for the new strings:
8 catalog entries (import, missing files, GPU notice, mask overlays),
3 format strings (other editor, identical copies) and the HLG label.

As in PhotoCraft: when portable.txt (or LightCraft.portable) sits next to the
executable, config_dir() is <exe dir>/LightCraftData, so settings, logs and
models stay with a portable copy instead of %APPDATA%. LIGHTCRAFT_CONFIG_DIR
still wins and is used without probing beside the executable. A portable
folder that can't be written logs a warning and the platform folder is used.
The check runs once per process.

With GPU rendering on and no graphics adapter at all (wgpu: "no GPU adapter among …", e.g. no
Vulkan loader: a `cargo run` outside `nix develop` on NixOS), every render ran on the CPU, much
slower, and only Settings ▸ Performance, Help ▸ System Info and `perf.gpuReason` said why.
The desktop app now queues one start-up notice per session once the device has been tried
(`gpu::ready()`, never blocking): "No graphics processor found: LightCraft renders on the CPU, which
is much slower. Details in Help → System Info.", on Linux with "On NixOS, start it from `nix
develop`." (→, not ▸: no installed font paints ▸.) `panels::notices::gpu_notice` decides from the
reason: nothing when the GPU was turned off (preference, LIGHTCRAFT_GPU, LIGHTCRAFT_GPU_BACKEND=off),
only a software adapter was skipped, or it failed later. Headless sessions and tests never show it
(`app.gpu_notice` is set by the desktop app only). Translated in all nine catalogs; one README
sentence in the Nix section.

File → Print… (⌘P) opens the Print module as a dialog: settings on the left,
the page drawn to scale on the right with the photos as they will print (fit
or Zoom to Fill, turned by Rotate to Fit, Photo Border, Inner Stroke, page
background).
Settings column: templates (save, apply, delete), layout style, image
settings, grid / package cell controls (standard and custom cell sizes, Auto
Layout, New Page, Clear Layout), rulers and guides (units in/cm/mm/pt, snap
off/cells/grid, grid size, margins, bleed, page grid, image cells,
dimensions), page setup (paper, orientation, margins), page background and
the print job.
Preview: rulers in the chosen unit, dashed margins and bleed, page grid,
dimension labels, page navigation. In the package styles cells are selected,
dragged (print.cell.move) and resized from a corner handle
(print.cell.resize) with the guides' snapping, arranged from the inspector
row or a context menu, and given a photo (Custom Package). Every change is a
print.* command; the drag is measured from where the pointer went down so
the click-versus-drag slop is not lost.
Print to PDF… picks a file and renders on a background thread with an
activity-stack row, cancellation and original protection, like the contact
sheet, which keeps working unchanged.
Headless tests drive the dialog with real pointer input through the control
channel (print:cell:N, print:resize:N, button:print*): styles and checkboxes,
add / drag / resize / arrange / delete, snapping to a neighbour, Auto Layout
and pages, templates, the PDF, the activity row, and that the dialog and its
buttons fit the window.
Add the Czech catalog (2,056 UI messages, 246 format templates), the
language-menu entry, locale detection (cs, cs-CZ, cs_CZ.UTF-8) and
regression tests for switching, persistence, dates, placeholders and
glyphs. Translate a few face/model, person and HDR/PDF captions through
the existing tr() interface. Settings > Language now wraps its buttons,
since twelve language names no longer fit a narrow window.

The header-only path added in #755 answers for a Fuji RAF, whose preview pointer sits in the first
bytes. A Canon CR3 keeps its preview in a JPEG track, and a TIFF raw (CR2, ARW, DNG, RW2, 3FR …) can
keep its preview tag in an IFD the prefix cuts short: both fell back to `std::fs::read` of the whole
file — tens of megabytes for a JPEG of a few, on the format of the largest bucket in gaps.md (Canon,
33 % of photographers).
`preview_window` now asks `lightcraft_raw::sparse::preview_plan` — the module #961 added for the
import path, which had no production caller — which ranges `embedded_preview` reads, and reads
exactly those: `planned_preview` fills a buffer of the file's length, reads the ranges the plan names
and asks again until it says `Ready`. The buffer is the file's length, which the memory gate counted
already, and its untouched pages stay zero, so what this path costs is the bytes read — on macOS a
freed buffer of that size may sit in the allocator's cache rather than go back to the OS (measured on
a 38k-photo import, #832). The loop gives up past 60 % of the file, the bound step 2's partial read
uses, and a plan that does not fit, a file past 1 GiB or a window that does not decode all end in the
whole-file fallback.
The quick path hands the JPEG to the decoder alone, so two container facts the whole-file path applies
have to be visible in the bytes it is handed, or the file declines and the whole file keeps the
preview:
- a preview colour space of Adobe RGB (`decode_raw_preview` applies it; a JPEG-only decode has the
JPEG's own space, else sRGB). A container that says sRGB does not decline — that is what the decode
assumes anyway, and declining it took the fast path away from a real Sony ARW;
- the file's own EXIF orientation, when the preview JPEG carries none of its own: the plan's header is
a bounded 64 KiB (the header route grows its prefix to the preview's declared extent instead), and
an orientation tag it cannot see would show the preview unrotated.
Measured over the whole CC0 corpus (111 raws): 52 files take this route, reading a median 7.8 % of
their bytes (0.9-27.7 %) — RW2 3.3 %, Leica RWL 4.1 %, ARW 7.5 %, CR3 8.4 %, DNG 9.7 %, CR2 14.3 % —
while the 21 RAFs stay on the header route (median 4.5 %). The other 38 read whole: NEF, NRW, ORF, PEF
and SRW because the planner does not describe them (an SRW plans to the whole file, which the 60 %
budget then declines), plus the ARWs, CR2s, CR3s and DNGs that declare Adobe RGB or whose plan wants
more than that budget — the bytes they read are the ones the plan would have read anyway. Across all
111 files the plan handed on the same preview as the whole file, with the skipped bytes zeroed and
again 0xFF. `LIGHTCRAFT_PROFILE=1` prints
[profile] preview …/arw-sony-a7rm4a-compressed.arw: read 688128 of 61832192 bytes (plan, window 483441)
Tests: a synthetic TIFF/DNG whose preview only its tags locate (identical pixels to the whole-file
path, the CFA strip unread), the same structure without the tag that makes it a raw, a file whose
orientation only the whole file shows, and a file that states Adobe RGB against one that states sRGB;
the opt-in real-file test reports which path answered.

All 110 CC0 CR3s on raw.pixls.us decode from sensor data; none uses a
refused CRX variant. One CC0 file per further body (1D X III, 90D, 250D,
850D, M200, M50 II, M6 II, R, R3, R5, R6, R6 II, R6 III, R7, R10, RP, R50,
R50 V, G5 X II, G7 X III, SX70, V1) is added to RAW_SAMPLES and pinned in
cr3_corpus.rs, checked against the camera's embedded JPEG.
The R6 Mark III writes ColorData version 66, laid out as 64/65; it lost
its as-shot WB and white level. Render cache 61 -> 62.
Also: as_chunks in spots.rs for the chunks_exact_to_as_chunks lint.
Docs: evidence.tsv + coverage re-measure (257 verified, 92% use-weighted),
gaps 2/10, checklist rows, raw-parity, target-app-parity, ROADMAP, README.

On merge: the quick preview path orients like the whole-file path (preview_orientation with the
raw's header prefix, so a portrait raw whose embedded JPEG carries no orientation is not sideways),
and its doc links point at preview_window.
On merge: the XWayland default goes in front of the catch_unwind-wrapped launch (#951), and the
README's Linux section names the LIGHTCRAFT_WAYLAND=1 opt-out.
storytold/craftrules is not a public repository, so the standards link in the
Chinese/Japanese fonts note was a 404 for anyone outside the maintainers. The
rule the sentence states lives with the font repo it points at anyway.

A grid thumbnail and a loupe preview of an unedited raw show the camera's embedded JPEG, which
sits near the start of the file — for a 24 MP Fuji RAF, 5.6 MB of a 56 MB file (measured:
DSCF9492.RAF). The loader read the file whole and threw the sensor data away, so every preview
paid for 50 MB nobody looked at. On a local disk that is merely wasteful; on a network share,
where photographers keep libraries, it is the wait: the same preview took 10 s over a GVFS/SMB
Wi-Fi share against 0.96 s after this change.
- `lightcraft_raw::bounded_preview(bytes)` locates the preview from the header alone and reports
its byte range; `embedded_preview_from_range` extracts it, byte for byte what `embedded_preview`
returns for the whole file (the pointer is read from the RAF header's fixed u32s at 84/88).
- `engine::files::preview_window` reads a 4 KiB prefix, then — because the container reader clamps
a slice to the buffer it was given, so a short prefix reports a plausible but truncated 3948
bytes — re-reads exactly the extent the header declares, and takes the window out of the prefix
rather than reading those bytes twice. `LIGHTCRAFT_PROFILE=1` prints what each preview cost.
- Formats whose preview only the whole file reveals (CR3 boxes, TIFF pointer tags past the prefix,
CRW/MRW/X3F scans), a lying pointer, a short read and a file that changes underneath us all fall
back to the whole-file path: a damaged header never costs the user their preview.
- Tests: the header range matches `embedded_preview` byte for byte, with a clamped prefix, a padded
extent, a late pointer, a lying pointer and a non-JPEG window covered; on a synthetic RAF with a
200 KB tail the quick path and the whole-file path produce identical pixels and the read stays
under half the file; `crates/engine/tests/preview_read.rs` (opt-in, `#[ignore]`) measures a real
file on a share. No raw fixture is committed.
- `docs/raw-preview-reads.md` records the mechanism and the numbers.

The interface ships in nine languages but the README only read in English, so a
Chinese reader met the project in a language it does not have to use.
README.zh-hans.md follows README.md section by section (569 lines, 27 headings,
7 tables, 8 code blocks), keeping every link, image, command, shortcut and
identifier byte-identical; only prose, alt text, code comments and table headers
are translated. Terminology follows the shipped interface catalog
(crates/ui-egui/locales/zh-hans.json) so the README and the app agree:
曝光, 白平衡, 颜色混合器, 胶片窗格, 留用, 正方形网格, 垂直校正.
Both files gain a language switcher at the top.
