Monochrome Images only took eight-bit grey of only black and white
besides 1-bit images, so the same scan written as RGB, or as an indexed
image of two palette entries, stayed at eight bits (and RGB went to the
colour settings, as JPEG). Now these are packed to one bit first:
- eight-bit DeviceRGB whose every pixel is black or white becomes
DeviceGray; a decode array the same for each component becomes that
pair, another stops it. Calibrated RGB and RGB with a profile stay.
- an indexed image of 2, 4 or 8 bits that uses only palette entries 0
and 1 keeps its palette, whatever the two colours; a decode array
other than the default stops it.
Colour-key masks still stop all of them, and Retain leaves them to the
grey and colour settings. They are decoded through /DecodeParms given
by reference too (Document::with_direct_parms), and when downsampled a
tie goes to the dark sample of the image as packed: packed RGB is grey,
with grey's decode pair.

The PDF Optimizer and Reduce File Size downsampled colour and grey images
but not black-and-white ones. Settings::mono is now MonoSettings {
downsample, target_ppi, above_ppi, compression }, 300 ppi above 450 ppi
and CCITT Group 4 by default (Monochrome Images ▸ Downsample to;
doc_optimize mono: { downsample, ppi, above_ppi, compression }).
A 1-bit image or image mask (no filter, general-purpose filters, or CCITT
fax after any of them) and eight-bit grey of only black and white are averaged by
area: each new pixel takes the sample covering more of it, a tie 0, so a
dark line half a new pixel wide stays. They are stored as Group 4, or as
1-bit Flate when that is smaller; with Retain a resampled image keeps its
kind of compression. Images with a soft mask keep their size.
CCITT decoding moves from Export ▸ Images into pdfcraft-filters
(decode_ccitt, CcittParams, through hayro-ccitt), and
pdfcraft_cos::Document::decoded_image reads a fax image's /DecodeParms
for it (undoing filters before CCITT, such as ASCII85Decode, with any
/DecodeParms given by reference made direct first), so export
and the optimizer share one reader, and Group 4 scans can be
downsampled. A 600 ppi text page went from 79 KB to 40 KB.

docs/architecture.md said every image codec decodes through the
bootstrap renderer; Export ▸ Images decodes CCITT (hayro-ccitt) and JPEG
itself. The progress logs' "(a dithered scan)" sat after "soft mask
counted", as if it described the mask, and so did the
optimize.mono-compression note's "(a dithered scan downsampled to JPEG)".

- A noisy 640 × 800 soft mask under 1200 × 1500 text: resampled to the
image's new size it shrinks only a little, by less than the grey
settings' JPEG adds over the packed image, so packing wins; not
counting the new mask passed every test before.
- The hex-text half of the bomb test also stores eight-bit
black-and-white, which must pack, as its comment says.
- The optimize README, the mono-compression parity note and both
progress logs say the soft mask counts.
- The Copy Image parity note no longer lists CCITT as missing: it
copies through Export's decoder, which reads CCITT now.

Group 4 images (now written by Create PDF and the optimizer) would
otherwise stop exporting: they were reported as "can't be exported
yet". A CCITT fax image (its only filter) is decoded through
hayro-ccitt with its /DecodeParms (K, Columns, Rows, EndOfBlock,
EndOfLine, EncodedByteAlign, BlackIs1), masks included; /Columns has to
be the image's width, so a hostile value can't size the buffers.

- Not only Export ▸ Images refuses a CCITT image until #4335: so does
everything that exports an image through it. Save Image As refuses
it, Copy Image fails, and Word, PowerPoint and HTML export leave the
picture out, with the page not reported. The optimize README and the
mono-compression parity note name them.
- optimize.mono-compression is partial now, so docs/target-app-parity.md
counts it on the table's own measurement: K Optimize and standards 15
shipped and 11 partial of 58 (35.3%), breadth 57.0% (423 + 75 of 808),
mainstream 63.3% (292 + 45 of 497), with a status line and a revision
row. ROADMAP.md's breadth rows and its K row say the same.

pdfcraft_filters::encode_g4 encodes packed 1-bit rows as Group 4 (ITU-T
T.6, /K -1) through the fax crate (MIT, already in the tree via tiff),
with rows capped at 32,767 samples so its 16-bit positions can't
overflow; round trips are checked against hayro-ccitt.
The optimizer (Settings::mono, CCITT G4 by default, so Reduce File Size
too) re-encodes a 1-bit image of one colour component, or an image
mask, stored with no filter or general-purpose ones, when that is
smaller as stored. The samples decode to the same bits, so colour
space, decode array and masks stay. PDF Optimizer gets a Monochrome
Images row and doc_optimize a mono option. optimize.mono-compression
goes from planned to partial (JBIG2 and monochrome downsampling not
yet).

The reading blocks keep style boundaries, so "Before Chevron after." with an
italic case name reached the Office exporters as three blocks, and each writer
emitted one paragraph per block. A block that continues another on the same
line (the test `continuations` already applies to keep such blocks out of
table cells) is now a run in its own size, bold/italic and colour inside the
paragraph of the block it continues, in Word, HTML, RTF and PowerPoint.
- `continued_from` names the block each one continues (nearest end);
`continuations` is its `is_some`, so table detection is unchanged.
- `paragraphs` groups blocks left to right, joining only a block that starts
strictly further left, with the same rotation, and never a table cell or the
slide title.
- Block text is trimmed, so the engine records the source's spaces at its ends
(`Block::space_around`, from the reading block's editor text); runs keep that
space, or one where the page shows a gap.
- A paragraph is a heading only if its runs are (a bold lead-in no longer makes
its line a heading); a smaller footnote marker does not demote a heading.
Style changes that wrap onto the next line still split paragraphs; that needs
the reading-block grouping change and is left for later.

* M3: give the kept button release back before the pointer leaves (Wayland)
After a desktop grab the next input on Wayland often brings only
PointerGone. The synthetic release went after it, and a button event
sets egui's pointer position, so the gone pointer came back and hover
stuck at the old place until the pointer moved. The release now goes
before the first PointerGone as well as before the first press; a
release that follows PointerGone is still the kept one and not doubled.
Found by CodeRabbit in review of #3970.

* M3: move a release that follows the pointer leaving in front of it
A release the input brings after PointerGone is the one the desktop kept.
Left after PointerGone, it brought the gone pointer back at the release
position; it now moves in front, still not doubled.

Conflicts:
- crates/render/src/inspect.rs: this branch's reply-linking methods and main's NoRotate
rectangles (#3016) both go in the Annotation impl; the annotation reader takes this
branch's loop with main's no_rotate field.
- crates/automation/src/comments.rs: this branch's HashMap import, main's import list.
- ATTRIBUTION.toml: each catalogue's source note keeps main's secured-document clause and
this branch's reply-count clause; ATTRIBUTION.md regenerated (cargo xtask assets --write).
- The 33 catalogues: main's new rows, then this branch's reply-count row.
main's #3016 tests build Annotation field by field; they now set parent and grouped.

ROADMAP.md, docs/roadmap.md: kept both sides' status and progress-log lines; did not restore the older M14 status line that the branch had already trimmed.
Conflicts: ROADMAP.md, docs/roadmap.md: both sides' status, progress and change-log lines; M10 row has the soft-mask sentence added to ours, M11 row from the earlier merge.
Conflicts: ROADMAP.md, docs/roadmap.md: both sides' status, progress and change-log lines; M10 row has both sentences. parity/acrobat-features.toml: export.docx evidence has both tests, notes has both statements.
Conflicts:
- parity/acrobat-features.toml: comment.note: kept main's icon notes text, added the NoRotate sentence and the PR's three evidence entries.
- vendor/README.md: kept main's rows; added the PR's hayro-interpret patch as (53) with its test (53).
Conflicts: ROADMAP.md and docs/roadmap.md took both sides' status lines, progress-log and change-log rows; M10 table row from #4311, M11 row from #4310.

Review: copying an added JPEG 2000 image failed even within its own
document, because the exporter can't write JPEG 2000 yet. Add Image stores
such a picture as the file it was given, so that file is the copy: it
pastes into the same document as the same object and into another as one
embedded image. The notes now also say that a CMYK picture stored
losslessly turns to RGB in another document.

Edit::PasteContent pastes an added text box or image copied in the same
document or another, as it was (a text box's style; an image's picture,
turns, flips and crop), as one undo step. A pasted image draws its picture
from the copied object while that is still the picture in the target, else
from an added image there that already holds it (an earlier paste from
another document), else the file is embedded. Document::added_image_file
gives a copied image's picture as a file and honours the copy permission.
pdfcraft_edit::added::paste_rect / paste_place place a paste where the item
was, 18 pt down and to the right past each copy of it on the page (an image
with the same box and transforms counts whichever object holds its
picture), or at a point, kept on the page.
The content_copy tool drives it headlessly, across pages and documents.
The desktop keys and menus come in follow-up PRs.

Edit text set a paragraph whose font lacks a typed character (an accent
missing from a subset) in a standard font, always under the resource
name PCEdHelv, whatever face it stood for. Rewriting a bold paragraph
after a regular one replaced PCEdHelv with Times-Bold, so every
paragraph set in the earlier stand-in turned bold, and the editor's
draft measurement saw those paragraphs change and grew its frame over
them.
The stand-in is now named after its face (PCEdTimesBold, ...), as the
line and region rewrites already name theirs.
