ExportOptions.dng_compression (`dngCompression`: lossless (default) | deflate | uncompressed),
in the export dialog when the format is DNG. Corpus-gated test: all three decode, uncompressed
is the biggest.

- develop.autoSync (Edit ▸ Auto Sync, ⌥⇧⌘A): an edit of the active photo carries only the
settings that changed to the other selected photos, in one undo step; slider drags sync on
release; spots / red eye and history restores stay per photo. Edit ▸ Sync Settings in the
menu; Edit panel banner while it's on with several photos selected.
- Colour-label sets: built-in Colors / Review sets plus user sets in prefs (label.sets,
applySet, saveSet, deleteSet); listed in Photo ▸ Set Color Label; the names dialog can start
from a set and save one. XMP sidecars and exported originals write the label's name, and
reading resolves custom names back to their colour.
- Crop: ⌘-drag draws a straighten line and keeps the crop tool active.

- Export watermark can be a graphic (watermark {image, imageWidth}): a logo with transparency,
scaled premultiplied to a share of the photo's width, converted into the output colour
space, placed with the same anchor / inset / opacity as text; decoded once per file.
Export dialog: Text / Graphic, Choose…, width; size and shadow apply to text only.
- Recently Added: everything imported in the 30 days up to the latest import, newest import
first, grouped by import day (was the latest import day only).

- Metadata gains alt text, extended description, sublocation, city, state/province, country:
catalog, photo.setMeta, copy/paste metadata, XMP read/write (Iptc4xmpCore AltText /
ExtDescrAccessibility / Location, photoshop City / State / Country), sidecars and export
(place fields dropped with "remove location").
- Info panel: camera card (camera, lens, size · file size, format badge, focal length,
shutter, aperture, ISO), then title, caption, alt text, extended description, copyright,
creator, file name (rename), file path (reveal), captured (edit), place fields, GPS.
- Text fields keep what is typed across frames and save on focus loss (they were rebound to
the stored value every frame). New pencil icon (drawn in code); dates::display_time.

- Engine: export split into prepare_export (session thread, cheap) and PreparedExport::run
(Send: read/decode/render/encode); run_batch with per-photo progress, cancel and collected
errors; export_batch keeps the stop-at-first-error behaviour for scripted calls.
- Desktop: the Export dialog, Export with Preset (menu and context menu) and Export with
Previous run their batch on a worker thread (app.export {background: true}); a progress
panel shows count / file / Cancel; ui.inspect reports export {running, last}.
- Headless: settle waits for a running export; `lightcraft-cli snapshot` finishes it before
exiting. Web keeps foreground exports (downloads are main-thread).

- Built-in export presets (JPEG Small 2048 px, JPEG Large full size, Original + Settings, DNG)
and user presets saved with the library (export.presets / savePreset / deletePreset);
app.export {preset, …overrides} everywhere (desktop, MCP, lightcraft-cli run).
- File → Export with Preset submenu (built-ins, user presets, Custom…); dialog: preset
picker, Save preset, Choose… folder picker, subfolder, if-file-exists (add number /
overwrite / skip), start number, TIFF compression (none / LZW / ZIP); {date} naming token.
- One export_batch for the desktop app and headless MCP (paths, conflicts, sidecars);
ExportOptions::to_json is the exact inverse of from_json.
- ⌘E = Export with Previous (alias); parity: Show in Finder row was stale.

- Resize modes: long edge, short edge, width, height, W x H (either orientation), megapixels,
percent; "don't enlarge" (default on); ppi written to JFIF density / PNG pHYs / TIFF tags.
- Full-size export of a cropped photo now renders the crop at native resolution (it was
upscaled to the uncropped long edge).
- Formats: Original (file copied byte for byte + XMP sidecar with the edits, named after the
output) and DNG (raw photos re-encoded losslessly, edits in the embedded XMP).
- Export dialog: Resize-to dropdown, values, Don't enlarge, Resolution; DNG/Original hide
pixel options.
- lightcraft-cli render goes through the shared exporter (colour space, metadata, ppi) and
takes any app.export option via --opt KEY=VALUE; MCP export schema lists the new params.
- xtask resolves the workspace root at run time (a moved checkout broke ci).

RenderRequest gains a sample format (OutputDepth: U8 for previews, U16, F32Linear); deep renders
run the per-pixel stage with the exact sRGB curve and return Rendered::deep alongside the 8-bit
image (GPU stays 8-bit: deep exports render on the CPU). Export encodes deep renders: 16-bit PNG and
TIFF, 32-bit float linear TIFF with a linear ICC profile we generate, 10-bit AVIF (YCbCr planes into
ravif). Output sharpening and watermarks work on deep images. ExportOptions.bitDepth with per-format
defaults (TIFF 16-bit, others 8-bit), export dialog bit depth choice (remembered with the last
export), MCP export schema. Tests: a smooth gradient has 1024 levels in a 16-bit TIFF vs 13 in
8-bit, float TIFF decodes to the same light as 16-bit, per-format depth rules, AVIF 10-bit.

RenderRequest gains an output space (default sRGB; previews stay sRGB). The per-pixel stage converts
scene-linear Rec.2020 to the target primaries, gamut-maps into the target gamut and encodes with the
target curve, on CPU and GPU (WGSL finish kernel reads the matrix, luma weights and curve from its
parameter block). sRGB output is byte-identical to before on the CPU. Export embeds our own
generated ICC profile for the space; AVIF stays sRGB. ExportOptions.colorSpace, export dialog and
MCP export schema. Tests: P3 colour survives a P3 export (decoded through the embedded profile),
every space/format round-trips its profile, GPU equivalence per space.

Export encoding lives in lightcraft-engine::export (pure bytes, shared by app/CLI/MCP/web).
Embeds our own sRGB ICC; writer creates the output folder.
