Fix-ups: diagnostic overlays never populate the view-preview cache; Photo Merge's RenderRequest gets
the new overlay field.

Photo Merge's Create Stack option now puts the merged DNG on top of a
collapsed stack of its sources (Catalog::stack_with_ops), so the grid
shows the result; test in tests_merge (and no stack without the option).
Photo Merge dialogs live in a Photo > Photo Merge submenu.

- engine: `merge.hdr`, `merge.panorama`, `merge.hdrPanorama` (bracket size from
EXIF); MergeJob (Send) with progress/cancel, preview renders through the develop
pipeline (deghost overlay, auto-crop frame); finish writes <name>-HDR/-Pano.dng
next to the first source, imports, selects, applies Auto Settings / auto crop
- ui: Photo Merge dialog (HDR / Panorama / HDR Panorama) with live preview on a
worker thread, background final merge with progress toast; context menu and
Ctrl+H / Ctrl+M (Ctrl now means the physical Control key on macOS)
- cli: `merge hdr|panorama|hdr-panorama`, `synth-merge` for synthetic inputs
- merge::synth: procedural brackets (DNG) and panorama views; docs/merge.md

Resolved: album.create (main's one-liner + smart: None), menus (panels in
the Window menu, main's dialog.newFolder ⇧⌘N, app.showInFinder and
app.exportPrevious placed in the menu layout), shortcuts (native-menu skip
+ main's aliases and UI-over-engine rule; Shift+X/Shift+U aliases go
through the culling path; my Shift+P/X/U flag-and-advance dropped in
favour of the aliases). X and Delete stay egui-handled (contextual keys).

Up to 8 OkLCh samples (pointColor.pick samples the colour after the mixer on a proxy render);
per sample hue/saturation/luminance shift, variance (compress/expand the spread around the
sample) and an overall + per-axis range with soft edges, applied after the colour mixer in
ColorOps and its WGSL twin (equivalence case). Indexed control specs
(pointColor.<i>.hueShift …) so develop.set/controls/MCP address each sample. Visualize range
is a render overlay (RenderRequest::overlay) drawn after either renderer: the sample's own
edit is left out and colours outside the range turn grey. Point Color flyout in the Color
section with swatches, eyedropper, sliders, visualize and delete.

Photo.copy_of / copy_name. photo.virtualCopy (Cmd+') clones the photo with
independent settings and history, names it "Copy N" (numbered per master),
adds it to the original's albums and stacks it (expanded) right after the
original; one undo step for several copies (Session::merge_undo). Copies
never write XMP sidecars. "Copy N" badge in the grid, Info panel line,
copy:yes search token. Also: Info panel stars laid out in a row.

Stack entity in the catalog (AddStack/RemoveStack/SetStack ops with
inverses, validation, snapshot + journal replay property test). Helpers
build ops for group (merging stacks), ungroup, remove, set top, collapse,
and stack_with_ops() for future merge results. Views arrange stack members
together and collapse to the top. Commands stack.* (Cmd+G, Cmd+Shift+G, S,
Shift+S, expand/collapse all, stack.auto with preview); grid/filmstrip
count badges (click to toggle), context menu, Auto-Stack dialog.

Album.smart holds Filter rules (rating, flag, label, kind, edited, keyword,
camera, lens, capture date range, text, album); SetAlbumRules op with
inverse, validation (no nested smart albums, no deleted), journal replay
property test. album.createSmart (from the current view or explicit rules),
album.setRules; New Smart Album dialog, smart icon, live counts.

`media::develop` renders on the GPU when available (views, render_now, exports;
thumbnails stay on the CPU) and falls back to the CPU otherwise. `app.gpu
{enabled?}` toggles it at runtime, `LIGHTCRAFT_GPU=0` disables it for the process,
`ui.inspect` reports the adapter under perf.gpu.
Performance: dropped device buffers are recycled once their thread has submitted
(fresh 100-300 MB allocations per pass cost as much as the passes), Gaussian
passes ping-pong between two buffers and read all channels of a pixel at once,
and long box radii slide over longer chunks. LIGHTCRAFT_PROFILE prints real GPU
stage timings. render_bench prints CPU and GPU columns and the CPU/GPU difference.
24 MP ARW, loaded machine, min of 7: cold loupe 415 -> 32 ms, exposure drag
22-42 -> 3.9 ms, NR drag (1920) 301+ -> 18 ms, export render 1037+ -> 291 ms;
max 1 LSB difference. docs/gpu-pipeline.md describes the implementation.

- engine::import: expand files/folders recursively (sorted; hidden entries
and the library folder skipped), skip known paths, probe + hash in
parallel (std::thread::scope), skip duplicates by content hash (against
the library and within the batch), add in place or copy into
<library>/Originals/YYYY/YYYY-MM-DD/ with unique names; one undoable op.
- library.import {paths, mode: add|copy, album?} returns
{imported, duplicates[{path, existing, reason}], failed, scanned}.
- probe_bytes records the content hash (SipHash-1-3 128) on every photo.
- system clock for import/edit times on native (Session::with_system_clock).
- app: command-line folders are expanded by the engine (re-importing the
same folder is a no-op); example gen_photos writes procedural test JPEGs
(never committed).
- Measured (200 procedural 2000 px JPEGs, M-series): import 2.25 s; reopen:
library load 1.7 ms, control ready 0.12 s, first thumbnail 0.17 s,
visible grid drawn 0.48 s (thumbnails from the disk cache).

- catalog: Store trait (FsStore: temp+fsync+rename+dir fsync; MemStore),
Journal: CRC-checked JSON-lines op log with sequence numbers + atomic
snapshots; torn final record dropped and truncated, stale records after a
snapshot skipped, mid-log damage preserved as catalog.log.damaged-N.
- PushHistory op so each edit logs one history step (not the full history).
- engine: Session::open_library/persist/close_library; every top-level
command is fsynced before returning; presets.json + view.json;
library.info / library.compact commands.
- app: default library ~/Pictures/LightCraft Library (LIGHTCRAFT_LIBRARY or
--library DIR override), --memory for throwaway sessions, snapshot on quit.
- tests: proptest replay(log)==state with random snapshots/reopens, every
truncation of the last record, stale log, mid-log damage, FsStore, engine
restart without close.

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.
