Read SMPTE 268M DPX in both byte orders (SDPX, XPDS): the first image
element, descriptor 6 (luma), 50 (RGB) or 51 (RGBA), at 8, 10, 12 or 16
bits, with 10-bit packing 0, 1 (method A) or 2 (method B) and 12-bit
packing 0 or 1. 10- and 12-bit code values open as U16
round(c * 65535 / (2^b - 1)) and come back exactly when written at their
depth. No colour transform: the transfer characteristic and colorimetric
specification are reported as import notes; extra image elements are
reported; the orientation is applied on import.
Write big-endian, one unencoded element, at 8, 10, 12 or 16 bits
(EncodeOptions::dpx_bits; `dpxBits` on the save commands, MCP and RPC;
`--dpx-bits` in the CLI), following the document depth by default. Gray
with alpha is written as luma. Creator, project, copyright, creation
time, transfer, colorimetric, frame position, frame rate and time code
travel as DPX:* text metadata and are written back.
Unsupported descriptors, signed or run-length-encoded data and other bit
depths return CodecError::Unsupported; malformed and truncated files
return errors.

- image.imageSize takes percent (both sides; an explicit side wins).
- actions.conditional {if, then, else}: Photoshop's Insert Conditional as a step, 33 conditions
on the document (shape, mode, depth, selection, layers, alpha channels, unsaved) and the
active layer (kind, locks, visibility, masks, effects); a failing branch stops the caller.
- .atn events: placeEvent → file.placeEmbedded/placeLinked (path, scale), open → file.openAs,
imageSize in percent, fill from a point → paint.bucket (pixels), conditional. 105 → 108.
- Panel labels conditional steps as 'If cond → then / else'.
- edit.transform gains the relative form (scaleX/scaleY %, rotate, dx/dy about the frame
centre), as a Photoshop action records a Free Transform; image.applyImage takes a source
layer by name.
- .atn events: transform (layer → translate or relative transform; selection →
transformSelection), applyImageEvent, export (Save for Web, with the txtu path record
decoded and written back; kept verbatim without a destination), newPlacedLayer /
placedLayerEditContents / updatePlacedLayer, close with the Save answer → save + close,
delete of the target channel → layer mask delete, Quick Mask on/off, polygon selections →
select.lasso, Gradient Map (direct and as an adjustment layer). 92 → 105 events.
- Export tries every event listing a command id (Quick Mask on → set, off → clearEvent).
- Docs: event counts in the parity docs.
* 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.
Opening a JPEG now estimates the quality it was saved at from its quantisation
tables (the Annex K tables of ITU-T T.81 scaled by the IJG quality curve; exact
for such tables, the closest fit otherwise). Opening a WebP records whether it
is lossless (VP8L) or lossy (VP8), and a lossy one's quality from its base
quantiser index. The settings live on the document (`Document::file_encoding`,
saved in .pcraft) and a save that asks for no quality writes the file back the
same way, as Photoshop's Save does: File › Save, Save As and Save a Copy start
there instead of the fixed codec defaults (quality 90, WebP always lossless).
An explicit quality still wins; new documents and other formats keep the
defaults. Hostile or truncated DQT/VP8 headers give no estimate, never a panic.

* feat(codecs): decode every frame of an animated GIF (#572)
decode_gif_frames returns each frame composited onto the logical screen
(disposal methods applied) with its delay in milliseconds. decode still
keeps the first frame only. A damaged later frame keeps the frames before
it and marks the first with DecodeWarning::Truncated; dimensions, the
total decoded bytes and a frame cap are checked against the limits.
* feat(io): import_gif_frames hands each GIF frame over as a document (#572)
A frame at a time becomes a single-layer document, so a caller can
flatten and drop it instead of holding every frame twice.
* feat(engine): animated GIFs load every frame into video layers (#572)
New Video Layer from File, Replace Footage, Reload Frame and Video Frames
to Layers take all frames of a GIF instead of the first. The timeline rate
comes from the GIF's delays (the most common one, delays under 20 ms shown
at 100 ms as browsers do); an explicit fps still wins.

* Add FITS read/write codec
FITS (the astronomy format) opens and saves as a flat image: the primary
HDU or first IMAGE extension; gray, or RGB when NAXIS3 = 3; BITPIX 8/16/
32/64/-32/-64 with BSCALE/BZERO/BLANK; rows follow ROWORDER (bottom-up by
default). Camera U16 data stays exact; float data is normalised to 0..1.
Header cards round-trip as text metadata (HIERARCH for long names).
Tile-compressed (fpack) files are refused as unsupported.
Wired into File > Open, Save As and the batch commands as .fits/.fit/.fts.

* Test FITS open and save through photocraft-io
Gray 16-bit, RGB 8-bit and RGB 32-bit float documents round-trip exactly,
and header cards travel as the document's text metadata.

Progress docs per craftrules standards/progress-docs.md: target-app parity (merges parity-estimate.md), gaps, roadmap with alpha gate, readiness by audience (full / mainstream / essentials) with Opus 5.5 hours, and UI, brush, format, hardware and localization parity docs. docs/parity.md is now docs/parity-checklist.md.
The Windows test failure (file_dialog::tests::save_dialogs_remember_where_each_document_was_last_saved) is pre-existing on main: the test hard-codes POSIX paths.
