On some Windows machines FXC fails to compile egui's own shaders on DX12
("The parameter is incorrect. (0x80070057)" in egui_pipeline) and wgpu's
default error handler panicked. Each renderer (DX12, Vulkan, GL, glow) is
now probed with error scopes and a logging error handler before the window
opens; the one that works is remembered; a start that dies leaves a marker
and relaunches with the next renderer. LIGHTCRAFT_GPU_BACKEND=glow added.

Port of storytold/photocraft#2445. Each theme in Settings > Interface gets a
star; starred themes are saved with the settings and listed in a right-click
menu on the title bar's appearance button, next to Appearance Settings, so
switching between favorites takes one click. The theme cards now list one
theme per row to make room for the stars, so the settings dialog test
scrolls further to reach the controls below them.

New crate lightcraft-geocode (L1): parses the GeoNames cities dump and finds the
nearest place within 50 km through a 1-degree cell index; NaN / out-of-range
positions and malformed lines find nothing. Engine commands
metadata.reverseGeocode (Photo menu, Info panel "Fill Location"; fills only
empty fields unless overwrite, one undo step, activity row for batches),
metadata.downloadPlaceNames (background download of the CC-BY 4.0 GeoNames
files into the settings folder, cancellable activity row) and
metadata.placeNamesStatus. No data is bundled; NOTICE records the licence.
Fixes#582.

folder.create {parent, name} makes a folder on disk (one undo step; undo
removes it again while it is empty). photo.moveToFolder {folder, ids?}
moves the photos' files with their XMP sidecars into another folder and

A raw shot in a monochrome picture style records full colour, but its
camera JPEG is grey: neither the full look nor the partial look has
colour to fit, so the photo started from the spectral matrices or the
neutral fallback with the default tone curve, about 1.3 EV darker than
the same body's colour-shot photos. The grey JPEG still shows the
camera's tone curve.
When no look was fitted and the JPEG is black and white (`monochrome`),
fit the quantile tone curve alone on top of the colour the photo gets
otherwise: the camera profile's (in `fit_preview`), else the spectral
matrices or the fallback (`monochrome_look`, after the spectral step).
The chroma curve stays neutral; the partial look's checks apply. A
tone-only look keeps the file's colour model for white balance.
LOOK_VERSION 2 -> 3, RENDER_CACHE_VERSION 42 -> 43.

export_progress_and_cancel failed every time on a fast machine (M5 Max, 4
export lanes): the 8 demo photos exported within the 100 ms progress
throttle, so the first progress above 0 was the final 8/8 and the cancel
arrived after the export had finished (a reply to the cancelled request,
or all 8 files on disk).
The test now wraps Headless in a test-only backend that, at the first
photo boundary, keeps polling the server's real progress hook (which
answers pings and reads cancels) until the cancel is read or the test
releases it, bounded at 20 s so a broken cancel fails rather than hangs.
The first export is released once the mid-batch ping is answered (that
was the same race), the second only ends by the cancel. That makes the
outcome exact, so the check tightens from "1..7 files" to "exactly the
one completed photo", which also proves the photos the other lanes had
already rendered are never written. No production code changes.

View > Export Slideshow... (and Export PDF / JPEG / Video in Settings >
Slideshow) writes the photos in view as their composed slides, between
the intro and ending screens that are on:
- PDF: a page per slide (1024/1920/3840 px long side, JPEG quality),
/Dur and /Trans fades per page, optional /PageMode /FullScreen. The
contact sheet's writer moves to engine/src/pdf.rs and streams to disk.
- JPEG: <name>-001.jpg... in a folder.
- Video: AV1 (rav1e, speed 10, low latency) in MP4 or WebM written by
our own muxers (codecs/src/video.rs); fades rendered as blended frames,
held slides one key-frame sample with a long duration; 720p/1080p,
24/30 fps; no audio; capped at 2 hours.
slideshow.export runs in the background with a row in the activity
stack (activity.cancel stops it); outputs are written as .part and
renamed when complete, so cancel or failure leaves nothing behind. A
photo that can't be rendered is skipped with a warning.
slideshow.exportStatus reports the result.
Soft Proofing's Profile menu takes a printer / paper ICC profile (Other…;
`view.softProof {profile, intent, paperInk}`), RGB or CMYK, matrix or LUT.
The CMS (moxcms) builds a 33^3 proof table over the working space: forward with
the chosen intent (Perceptual / Relative), back relative colorimetric; the
destination gamut warning comes from the colorimetric round trip. Simulate
Paper & Ink renders absolute colorimetric: the profile's media white replaces
screen white and the ink black is unscaled. The pipeline gets the table by id
(`Proof::profile`, `register_proof_profile`), so Proof stays Copy and render
keys include it. Proof copies are named after the profile.

New `inpaint` crate (L1): multi-scale patch-based completion with a PatchMatch
nearest-neighbour field, seeded by a membrane fill. Deterministic, no panics on
hostile sizes, cancellable. Ported from PhotoCraft (MIT OR Apache-2.0).
Remove tool: a fourth spot mode, `fill` ("Content-Aware"), rebuilds the spot
from patches of its surroundings instead of one source; coarse-to-fine, so the
structure is chosen at a scale set by the spot size and preview and export agree

HsvTable::apply took the value through linear -> sRGB -> linear even when the table's value
scale is 1 (every hue/saturation-only table, as fitted camera looks are), and wrapped hues with
rem_euclid (an fmodf call) three times per pixel. The value is now kept as it is for a unit
scale and the sRGB-encoded value is reused otherwise; hues are wrapped by a helper that equals
rem_euclid bit for bit (tested) without the call for values within one period.

A noise-reduction change invalidated the scene-linear stage and with it every spatial
plane (base, clarity, dehaze, chromaticity), so each tick of an NR drag on the CPU rebuilt
all of them. The plan now also carries the linear key without the NR settings; a draft
render whose image differs from the cached one only in NR keeps those wide blurs and redoes
only log luminance and the fine texture band. Full-quality renders never take them.
Draft NR drag, single thread: prepare 18.7 -> 7 ms (render ~135 -> ~125 ms CPU).

Previously the masking overlay showed only the selected mask's region
(toggled by O). This adds a new Overlay::AllMasks variant that paints
the evaluated alpha of every visible mask that has components in one
tint, wired to a new "Show All Mask Overlays" command (Ctrl+O on
Windows/Linux, Cmd+O on macOS) reachable from the View menu, the
masking panel header (stack icon), and the keyboard shortcut.
Both the CPU and GPU render paths evaluate all visible masks and hand
their alpha planes to visualize::apply, which layers each mask's
region so multiple masks are visible at once. The all-masks overlay
takes precedence over the single-mask overlay so the shortcut is not
shadowed by the always-on per-mask view.

replaced ones as "previous" for the session (prefs have no undo).

Cinema Wide, Shooting Data (no Lightroom names or designs, no images).
- Commands slideshow.templates.list/apply/save/update/rename/delete/

limit and 8-bit symbols, without its minus-one offset). The old rule (an
escape after 16 zeros with a 16-bit literal) matched only the first symbol,
which is all the R8 and R7 maps need. R5 Mark II maps (QP 150-162) jump by up
to 12 where the Rice parameter is 0, giving 18- to 22-zero prefixes that

Rebased onto the activity stack (#601). An export adding its files to
Photos keeps its row through that step, with "Adding to Apple Photos…" as
the detail. The worker turns the row's ✕ off (TaskHandle::set_cancellable)
before its last look at the cancel flag and reports what it saw, so a
cancel either stops the export before Photos is asked or is refused, never
both "cancelled" and imported. activity: a per-task gate orders a cancel's
decision against a step switching cancelling off, so a cancel can't be
accepted between the switch and the step's look at the flag and then be
ignored. An import of its own (export.addToPhotos, or
the Photos step left running after a foreground app.export) holds a row of
kind applePhotos while Photos works: no ✕, no count, the album as detail.
The desktop app refuses export.addToPhotos {wait: true}: its window's
thread never waits for Photos. The label is in every catalog; tests assert
the rows, the refused cancel and the refused wait.

- Ten minutes plus five seconds a file per import (was one minute): the
first live run timed out while macOS's permission prompt was still up,
and Photos' duplicates question waits for a person too.
- Files go to osascript 200 at a time, all within the import's one time
limit: one run with every path went over macOS's 1 MiB argument limit
at about 10,000 files, and Photos got nothing. A failed later batch says
how many files Photos had added.
- The progress line "Adding to Apple Photos…" is translated on the UI
thread; on the export worker it was always English.
- docs/apple-photos.md: who can add what (the control port is reachable by
any local program, other users' included), batching, the new limit, and
tested end to end (macOS 26.6.2, Photos 11.0, packaged app). The parity
row says so; What's New has an entry.

The Export dialog gets "Add to Apple Photos" with an optional album (macOS
only). app.export takes addToPhotos / photosAlbum (dialog, Export with
Previous, presets, MCP, lightcraft-cli run and render --opt); the new
export.addToPhotos {paths, album?, wait?} adds files already on disk and
export.photosImports {job?} reports how imports went.
A constant AppleScript run by /usr/bin/osascript asks Photos' import
command (Apple Events, not synthetic input) to import the files into a
top-level album of exactly that name (made when missing; albums in folders
are never used; several of that name: refused), skip check duplicates
false, and returns the media item ids. Album names and paths are passed
only as separate arguments (on run argv), never spliced into the script.
The runner is injectable (Session::apple_photos): with_fs installs the real
one on macOS only, and tests use fakes, so no test starts osascript or
Photos.
Imports are jobs (Session::apple_photos_imports), one at a time. The
desktop app (Session::apple_photos_background, set in open_session) never
waits for Photos on its UI thread: the background export adds on its
worker, app.export without background and export.addToPhotos answer with
the running job, and the app announces the outcome. Without a window (MCP,
lightcraft-cli) imports wait by default, and both headless front ends (the
MCP/CLI backend and the snapshot UI) wait for a running one before the
process ends, on every exit path, through one engine helper
(Session::wait_for_photos_imports) whose deadline follows the job: a
writing allowance while an export still writes, then the import's own
time limit from when Photos was asked, under an overall cap. A runner that panics, waiting or on a
worker, ends its import as failed and frees the slot (panic guard plus a
completion guard). Session::after_export reserves
the import slot before an export writes anything and frees it on every
exit path (handed the files, cancelled, failed, dropped), so a competing
import is refused with the export's job number instead of the export
failing its Photos step after writing. Permission (-1743), missing Photos,
cancel, timeouts, ambiguous albums, busy imports, other osascript failures
and partial imports produce actionable messages; the export's files are
kept either way. Hidden on other platforms; the web build compiles it out.
Packaging: the hardened-runtime entitlements gain
com.apple.security.automation.apple-events (app and CLI) and Info.plist
gains NSAppleEventsUsageDescription, without which macOS refuses the
events without asking.
Not yet tested end to end against a real Photos library: manual steps,
with the packaged app, in docs/apple-photos.md. Parity row LR-EXP-PHOTOS is

Open Library given a Lightroom Classic catalog folder, one of its .lrdata /
.lrcat-data folders, Backups/, the .lrcat or its -wal/-shm/.lock files used to
create an empty LightCraft library inside Lightroom's folder (or, for the
.lrcat file, close the current library and then fail). Now:
- engine: lightroom_folder::lightroom_catalog_at (names only, top-level scan
bounded to 10 000 entries, never fails); Session::open_library refuses those
places with EngineError::LightroomCatalog {path, catalog} before creating
anything. A LightCraft library (catalog.snap / catalog.log) always wins.
- app: app.openLibrary checks before closing the current library, keeps it,
returns {opened: false, lightroomCatalog, path} and shows a dialog with
Import Lightroom Catalog… (file.importLightroom with the catalog found) and
Cancel. The library problem window gets the error instead.
- Lightroom import status keeps the catalog path after the task ends.
- CLI --library explains how to import instead.
Intro and ending title screens (Lightroom Classic's Titles panel): each on
or off, a background colour and, centred, the Overlays identity plate or a
line of text, in the plate's colour or an override colour, at a scale, for
its own duration (default: the slide duration).
- Playback timeline: titles are items (Item::Title) of Playback; the intro
plays once before the first photo, the ending after the last photo when
repeat is off; random order never moves them; arrows step across them;
fades, pause and readiness work as for slides; n of N counts photos only.
- Engine: slide_title (TitleSettings in prefs.json, TitleCompose drawing
through the slide composer and overlay text renderer), slideshow.titles
get/set, slideshow.preview {title}.
- UI: titles composed on a render worker (Renderer::request_title), the
control bar shows Intro / End, Settings > Slideshow > Titles section and
a Photo / Intro / Ending preview choice; strings in the nine locales.
- Docs: parity row (partial), playback note, whats-new, control and MCP.
Compare and Reference drew each pane from a whole-frame render of at most
2560 px, so 1:1 was a magnified preview and focus could not be checked.
Each pane now also renders the window on screen from the photo's own
pixels (Slot::CompareRegion), as the loupe does (#323). The media cache
keeps up to two full-size originals while either view is open, so one
pane's window does not evict the other's source.

HDR editing is switched with an HDR button in the Edit panel header, beside
Auto and B&W and drawn the same way (the shared text_button: highlighted
while on), instead of a checkbox at the top of the Light panel. While HDR is

the light sliders; with HDR off they're hidden.

An HDR edit's preview shows its SDR rendition, so its histogram said nothing
about the highlights above SDR white. Now it shows the HDR rendition:
`pipeline::hdr_histogram` renders the edit small (384 px, float HDR, same
framing) and bins it with SDR on the left half and the HDR range on the right
(`Histogram::of_hdr`, `HdrBins`), on a fixed scale of Hdr::MAX_EV_LIMIT (5)
stops above SDR white so it doesn't rescale when the headroom limit changes.
The engine's `develop()` (CPU and GPU renders) and the web worker swap it in
for HDR edits; high-bit-depth, windowed and proofed requests keep the image's
histogram, and a display profile's histogram doesn't replace it. Web workers
carry the HDR bins across their wire (`Histogram::to_words` / `from_words`).
The panel draws it in Lightroom's layout: a solid line at SDR white, dashed
lines between the stops, the headroom limit as an orange line with the range
past it dimmed, a bar under the plot (white; one band per stop in Visualize
HDR range's colours while that is on), SDR / HDR labels and an info tooltip.

With HDR output on, a photo edited in HDR exports as a 16-bit PNG with the PQ
curve in Rec. 2020 (SDR white at HDR_REFERENCE_WHITE_NITS), described by a
`cICP` chunk (PNG third edition: BT.2020 primaries, PQ, RGB, full range) and
a `cLLI` content light level chunk (the levels the HDR AVIF records). EXIF,
XMP and print resolution are kept; no ICC profile next to cICP. Photos without
an HDR edit, and HDR edits with HDR output off, export as before.
`codecs::encode_png_pq` sits next to `encode_avif_pq` and takes the same
input. Follow-up to #646, ported from #466.

Raws with a fitted camera look (e.g. Nikon NEF) rendered HDR with the
generic tone curve instead, more than a stop darker through the midtones
than the SDR render: PQ JPEG XL / AVIF exports looked dark everywhere,
and gain map JPEGs carried negative gains, so they went dark on HDR
displays. ToneMap::camera_hdr keeps the camera curve up to 1.5 EV over
grey and lifts highlights as ToneMap::hdr does.
