a7301f1db8 PSD: cap pattern memory across a parse, reject mixed-depth pattern channels (#5198) (#5207)
* TIFF: read and write CIE L*a*b* (CIELab, ICCLab); Lab documents stay Lab

Photoshop saves Lab documents as CIELab TIFFs (PhotometricInterpretation
8, a* and b* signed), which PhotoCraft could not open, and PhotoCraft
saved Lab documents as sRGB TIFFs.

- codecs: a Lab channel layout (Lab, LabA) holding a* and b* as
  PhotoCraft's Lab documents do ((a + 128) / 255; 16 bits like the PSD
  importer), with its own Lab <-> sRGB conversion (same formulas as
  photocraft-color; codecs stays standalone) for formats without Lab,
  which now warn LabConverted.
- TIFF read: CIELab and ICCLab (8 and 16 bits, alpha) are handed to the
  tiff crate as RGB and labelled Lab; a* and b* are converted from the
  file's encoding (signed a / 256a, or offset).
- TIFF write: Lab and LabA as CIELab, as Photoshop writes it; float Lab
  is written with 16 bits (DepthReduced).
- io: a Lab TIFF opens as a Lab document; a Lab document with one plain
  layer is written to TIFF in Lab (other formats still use sRGB).

Photoshop 2025's Lab TIFFs open with the colours Photoshop shows (its
own RGB conversion matches within one level at 8 bits and exactly at 16
bits), and Photoshop reads PhotoCraft's Lab TIFFs back with the same
L*a*b* values.

* Raw: measure the Nikon D90 image area (4288x2848 at (10, 10))

Aligning the decoded D90 sensor plane with the camera's own JPEG puts the
image at (10, 10) in the 4352x2868 sensor plane, giving the camera's
4288x2848 frame (10-pixel margins; the right border reads the camera's flat
255 from column 4310). Add the measured ImageArea so a D90 NEF opens on the
camera's frame instead of the uncropped plane, and make a measured profile
leave a file that carries its own colour calibration (a DNG) untouched.

* Codecs: open Cineon (.cin) film frames read-only

Cineon is the 10-bit logarithmic film-scan format DPX grew from. Read it from
the same Kodak header family: the generic header (big-endian, orientation at
192, channel count at 193, the channel-1 bits/dimensions), one or three
channels, three 10-bit samples packed into each 32-bit word on a word
boundary. The 10-bit code values open as U16 (round(c x 65535 / 1023)); the
file's log black/white points are a display choice and are not applied. A
depth other than 10 bits or a channel count other than 1/3 is Unsupported;
truncation errors rather than panicking. Read-only (no Cineon writer), so
.cin joins the open filters and Cineon read closes part of #1049's G10 gap.

* PSD: cap pattern memory across a parse, reject mixed-depth pattern channels (#5198)

- Patterns: one PatternBudget (decoded bytes + zero padding) is shared by
  every pattern of a block, a .pat file and the pattern blocks of one
  document; .abr patt sections are charged to the samples' budget.
- Patterns: a channel whose depth differs from the first is rejected (the
  parsed pattern could not be written back).
- Slices: descriptor numbers no longer wrap; out-of-range ids are no id,
  coordinates clamp to i32, and a v6 trailing entry without a usable id
  attaches its outsets to no slice.
- LayerInfo::unpadded_len is computed from field sizes instead of
  serializing every record into a scratch buffer.
- abr desc presets are moved out instead of cloned; UnFl and shmd counts
  use the bounded preallocation; ImageData::decode_channel (decoded every
  plane to return one, unused outside its test) is removed.

* PSD: write tiff blocks without copies, inflate merged ZIP once

- ImageSourceData::to_bytes writes the global mask and global blocks
  straight from the model with 4-byte alignment instead of cloning each
  block (data included) to set its padding. Same bytes.
- The tiff transcoder's nested regions and blocks write into the parent's
  buffer (taken and handed back, error or not) instead of building their
  own output and copying it up per nesting level. Bodies that fail or are
  not transcoded are truncated before being copied as stored or dropped.
  Same bytes.
- PsdFile::from_bytes_and_merged decodes the merged image with the parse
  when asked: a ZIP stream is inflated once (the decode's stream check is
  the parse's); the parse-only check runs only when the decode fails, to
  keep from_bytes' errors. PSD import uses it with merged_needed.
- PsdBuilder::composite documents that Gray/CMYK composites stay straight.

* Content-Aware Fill: measure a thin hole by its thickness, not its bounds (#1366)

Removing long, thin objects (coiled guitar strings, wires) left their
outline as darker and lighter blotches and copied pieces of other strings
into the fill. The pyramid shrank until the hole's bounding box was four
patches across: for a string across the image that is a level where the
hole has swallowed its surroundings, so the matches found there copy
whatever looks like the blur, and the finer levels (refine-only for wide
bounds) keep them.

A hole at most a quarter as thick as its bounds are long now counts as
thin: the pyramid stops while it is still about two patches thick, and
that level starts from a membrane across it (over a few pixels, the
surroundings themselves) instead of the onion peel, whose exhaustive
search is what made a shallow pyramid unaffordable. Compact holes are
unchanged bit for bit.

* perf(compose,gpu): effect caches reserve tile addresses instead of pinning layers

Effect map cache entries kept a clone of their layer (a deep clone for groups) so the tile addresses the cache key hashes couldn't be reused. That kept an edited or deleted layer's pixels alive, uncounted, until the entry was evicted. Keep a Weak to each hashed tile instead: it reserves the address without keeping the pixels. The GPU compositor's styled-group pins and shape-source tile snapshots do the same. Part of #4530.

* fix(history): count snapshot-only tiles against the history budget

History panel snapshots outlived every budget: a Merged Layers snapshot is a full flattened copy that neither the history budget, the GPU budget's document bytes nor Purge accounted for. Trim now counts the tiles only snapshots hold as fixed cost, the GPU budget includes them, and Purge > Histories no longer reports tiles a kept snapshot still holds as freed. Part of #4530.

* Content-Aware Fill: every part of a thin selection keeps its surroundings (#1366)

Two more causes of ghosts when removing strings and the small knobs
selected with them:

* Auto sampling summarises the selection's surroundings by a few
  clusters. Around a long selection those come from the strings'
  surroundings, so a small part elsewhere (a tuning knob in a differently
  coloured corner) lost its own surroundings and was filled from far away
  in another colour. Around a thin selection the Auto area now always
  reaches as far as the selection is thick.
* The membrane that starts a thin hole now starts a patch radius out, past
  the anti-aliased fringe or halo that a selection drawn close to the
  object leaves outside it.

Refs #1366

* Content-Aware Fill: peel a thin hole where that stays affordable (#1366)

Starting every thin hole from a membrane smoothed Spot Healing on film
grain (spot_healing_keeps_film_grain_through_overlapping_strokes: grain
9.0 against 12.1 around). The onion peel copies the grain; it was only
given up because its exhaustive search is too slow on the big level a
long thin hole stops at. It now starts the thin hole whenever hole cells
times sources stay within 2^28 comparisons, and the membrane only beyond.

* Select Subject: keep subject parts coloured like the backdrop, leave enclosed gaps open

Users on #2788 reported Select Subject dropping clothes that are close in
colour to a plain wall and bridging the gap between an arm and the torso.
Both come from the same place: the saliency pass labels low-contrast parts
of the subject as background, the background colour model then learns
them and explains them away, and the final blind hole fill closes every
enclosed gap up to 5 % of the mask.

Two changes in crates/algo:

- A second GrabCut pass whose background model only knows the backdrop. A
  colour model fitted to the image frame (minus a margin around the
  salient blob, in case the subject runs out of the picture) marks every
  pixel it explains as probable background; the blob and whatever the
  backdrop cannot account for start as probable foreground. Only
  components that touch the first pass's result survive.
- Hole filling that consults the colour models: specks (<= 0.2 % of the
  mask) always fill, larger holes up to 5 % fill only when their pixels
  fit the foreground model better than the background's.

Tests: two regressions (a cream-shouldered figure on a near-white wall
keeps its shoulders; a ring keeps its backdrop-coloured hole open), plus
ignored timing and picture-dump helpers. The 6 MP first run goes from
about 100 ms to about 200 ms on one core; the P29 repeat path is untouched.

* Keyboard shortcut sets: Set menu, New Set, Save, Delete, .kys Export and Summarize (K2)

Edit › Keyboard Shortcuts gets Photoshop's set management. A set is a saved copy of the
bindings (Preferences.shortcutSets, the one in use in shortcutSet; "" is PhotoCraft Defaults),
and the Set menu shows "(modified)" when the bindings differ from it. New Set…, Save and
Delete wait for OK like the rest of the dialog. Export… writes the dialog's bindings as a .kys
file (commands then tools, Photoshop's macOS key spelling), each row carrying our id as pc-id
so PhotoCraft imports its own sets back exactly, whatever the label; Summarize… writes
Photoshop's HTML list of every bound command by menu.

edit.keyboardShortcuts takes useSet (before the call's edits), saveSet, deleteSet, sets and
activeSet (after them), exportKys and summarize; every reply reports the sets, the set in use
and whether it is modified. Bad names, keys or counts are errors that change nothing.

* .kys import: tool keys and sets saved on Windows (K3)

Photoshop's <tool> rows now import: each matches our tool by name (our tool names are
Photoshop's) or by pc-id in sets PhotoCraft exported, and a letter other than the tool's own
becomes its override, while its own letter keeps the tool cycling with the others (#5036).

A set saved on Windows spells the primary modifier Ctrl where a Mac set writes Cmd and keeps
Control for the Control key. A set with no Cmd or Opt anywhere but some Ctrl is read as a
Windows set, its Ctrl as our Cmd: Ctrl+L is the Cmd+L default, not a Control-key override that
would also mean Control on a Mac. The import reports `windows`.

* cargo fmt the extension lists

Fabio Lissi 3204231d7d Load and save Photoshop Actions (.atn) (#4356, #219) (#4434)
* Load and save Photoshop Actions (.atn) (#219)

- photocraft-psd: `atn` parser and writer for version-16 action sets, exact round trip,
  truncation/garbage safe, fuzz target and `atn_dump` example. Descriptor fix: `indx` and
  `Idnt` reference items carry a class before the number (real action files failed to parse).
- photocraft-engine: `atn_cmds` maps 92 Photoshop events to commands and back (filters,
  adjustments per channel, image/canvas/crop/trim/rotate/flip/mode, make/set/select/delete/
  hide/show/move/duplicate, fill/stroke, selection, clipboard, purge, profiles, play, stop).
  Other steps load as `actions.photoshopStep` (descriptor kept, written back by save, fails at
  playback by name); tool selections load switched off. Commands `actions.load`,
  `actions.save`, `actions.stopMessage`, `actions.photoshopStep`. `Action` gains `dialogs`
  and `set`. `layer` params accept a layer name, so loaded steps replay in any document.
- UI: Actions panel menu › Load Actions… / Save Actions…; Photoshop steps labelled.
- CLI: `batch --actions set.atn`. Automation policy covers the new path params.
- Docs: file-format parity (.atn R/W), gaps G11, target-app parity, scorecard AUTO-219-2
  partial, development guide.

* Translate the Actions panel's Load/Save strings in every catalog

The eight new panel strings (Load/Save Actions…, the loaded/saved counts, the kept-step label)
were missing from all 19 catalogs; the languages that were complete are back at 100%.

* Show the Actions entries in the default dock's panel menu

The legacy dock renders its own group menu and only knew the Layers and Swatches entries, so
Load Actions… and Save Actions… were missing there.

Valentin KleinandClaude Opus 5.5 fd351918e5 PSD: cap the layer tree for psd_to_document; layered TIFF checks group depth (#2940) (#2975)
The file-open path rejects PSDs nested past MAX_GROUP_DEPTH before
conversion, but the public psd_to_document built file.layer_tree() to the
file's full depth (~16000 levels) before Ctx::build capped it, and layered
TIFF reached it with no preflight at all.

- photocraft-psd: PsdFile::layer_tree_max_depth(n) builds the tree
  iteratively and drops the children of groups nested n deep, so walking
  or dropping it recursively is bounded. layer_tree() is the uncapped case.
- psd_to_document uses it with MAX_GROUP_DEPTH, the same cap Ctx::build
  and apply_link_groups apply, so imports are unchanged.
- Layered TIFF rejects nesting past the cap with the same error as a PSD
  (shared psd_import::check_group_depth).

Valentin KleinandClaude Opus 5.5 0fb4bbf1db PSD: don't inflate an over-budget ZIP merged image at parse time (#2926) (#2967)
validate_planes bounded its zlib loop by the uncapped declared size, so a
PSD/PSB declaring more than MAX_DECODED_BYTES of merged image could make
PsdFile::from_bytes decompress far past the decode budget before any
error. decode_planes refuses such a layout with LimitExceeded anyway, so
the stream is now kept verbatim without inflating it, like an unknown
compression method. A layered file whose merged composite is too large
still opens (the importer only warns when the composite can't be decoded).
