* M11: JBIG2 images share a symbol dictionary, up to 16 at a time
With Monochrome Images set to JBIG2, Optimize stored each image's
letters in a symbol dictionary of its own, so a document of N pages
carried its font's shapes N times. Now up to 16 images the run stores
as JBIG2 share one dictionary in a /JBIG2Globals stream, holding the
marks found in more than one of them; each image's text regions refer
to it first, then to a dictionary of its own for the marks only it
repeats. An image is stored that way when it comes out smaller, and a
group only when what its images save is more than the globals take.
- filters: encode_jbig2_shared codes a group: the globals are a symbol
dictionary segment numbered 0 and associated with no page (7.2.6);
each page numbers its segments from 1, as a segment refers only to
lower numbers (7.2.5), and the shared symbols' IDs come first, as the
dictionaries are referred to in that order (Table 31, SBSYMS). At
most 16,383 shared marks, those in the most images, so a page keeps
room for its own under the decoder's 32,767.
- optimize: the run holds the 1-bit samples of the images it stores as
JBIG2 (16 at most, 64 MiB at most) and stores them again sharing,
weighing each with the longest reference the globals could have.
Eight pages of 10 pt text rendered at 300 dpi take 41% less in
Helvetica and 42% in Times than coded alone, 10% in Courier, and 46%
in Helvetica at 600 dpi; groups of 2, 4, 16 and 32 save 19%, 33%, 45%
and 47%. Redacting one image stores the others of its group again
without the dictionary, so 16 keeps that to 15 images.

* M11: test what the mutants found untested in shared JBIG2 dictionaries
- filters: the group goes through encode_jbig2_shared, which refuses it
for an image the encoder refuses; two marks in common are enough to
share; past the 65,536 distinct marks a group holds, a mark first seen
later isn't shared while those held count every image.
- optimize: optimizing again keeps both the shared pages and the pages
coded alone as they are; under Retain, averaged JBIG2 pages share
nothing; a last group of two shares.

* M11: only images redaction can store again share a JBIG2 dictionary
Redacting one image of a group stores the others again without the
dictionary, which can hold the shapes of marks under the area, and
refuses the redaction for one it can't: it takes image masks and
images of one component as its own reading counts them (no DeviceN,
the family named directly), and at most 64 Mi pixels. Optimize took
DeviceN of one colourant and up to 80 million pixels, so such an image
in a group made any redaction of the others fail, where before it was
coded alone and the same redaction worked (the Consumers review).
Only an image mask or a DeviceGray image named directly, of at most
2^26 pixels, now joins a group; others are coded alone. An engine test
optimizes three pages, two DeviceGray and one DeviceN, and redacts the
first: the DeviceN page stays alone, the second is stored again, and
no image names the dictionary after a save.

* M11: optimize and redaction share one limit on the images redaction stores again
The second Consumers review: Optimize's limit on images that share a
JBIG2 dictionary copied redaction's private 64 Mi, with nothing tying
the two, so a lower one in redaction would bring back refused
redactions with no test going red. Both now read
pdfcraft_cos::MAX_REDACTED_IMAGE_PIXELS. The engine test adds an image
mask, the other kind that shares, so a redaction that stopped storing
either kind again fails it. doc_optimize's description, the README,
the parity note and ROADMAP say which images share (named directly).

* M11: a JBIG2 group is coded before its samples would pass the limit
CodeRabbit on #5910: hold added an image to the group and then checked
SHARED_BYTES, so a group could pass the 64 MiB it is documented to stay
within by its last image, which can itself be up to 64 MiB (an image
that shares has at most 2^26 pixels, and as its rows are whole bytes,
at most that many bytes; a 1-pixel-wide one takes them all). hold_in
codes the group first when an image would take it past the limit, and
after when it has 16 images; with room for 10 bytes, images of 4 go two
to a group, where the old order made one of 12. CodeRabbit's follow-up
too: the 18-image test decodes every image and compares it with its
samples, across the boundary between the groups.

* optimize: count the globals' object framing; filters: test the shared coder's size limit
- A JBIG2 group shares a dictionary only when it saves more than the
globals' dictionary and data plus NEW_OBJECT (96 bytes: the object's
framing, its xref entry, and an encrypted file's IV and padding), so a
group that saves less than that no longer makes the file larger.
- encode_jbig2_shared is Unsupported for an image taller than the
decoder takes and codes one at the bound.

bookmark_export returns an outline, or one bookmark's subtree, as JSON:
titles, nesting, open state, colour, bold/italic and destinations as page
plus view in PDF user space (ISO 32000-2 12.3.2.2), optionally written to
a file. bookmark_import takes it back, inline or from that file, under any
bookmark at any position or in place of the outline, as one undoable edit;
bookmark_copy does the same from another open document by page number.
A bookmark whose page the target lacks keeps its place without a
destination and is reported in `unmapped`. Every node is checked before
anything is written (title, page, colour, view type and arity, 33 levels,
100,000 bookmarks), and the error names the node.

* M11: Optimize runs when a category it discards holds nothing
PDF Optimizer's Discard Objects ticks pass their categories to
remove_hidden, which refuses a run that removes nothing. Ticking "Discard
bookmarks" on a file without bookmarks, or doc_optimize with such a
discard, ended the whole optimization with "there are no redaction marks

Its error came from remove_hidden's refusal: "there are no redaction marks

and says there is nothing to remove. The scan counts what removal takes
(an AcroForm with no fields as 1), so the check refuses only what the
removal would. The tool description says it fails then.
The tool test also runs doc_optimize discarding categories that hold
nothing, end to end.

Catching remove_hidden's refusal kept a copy it may have changed: with
bookmarks ticked it drops an empty outline root before counting nothing,

scans first and passes only the ticked categories the scan finds something
in, and with none doesn't call it, so an empty outline root stays, as
Remove Hidden Information leaves it.

removed now share the one scan the tool took already.
Corrects ada2a1ccb's message: the removal also takes what its scan counts

refuses when its scan counts every listed category as 0.

c7c018ac6 passed remove_hidden only the ticked categories its scan finds
something in. But with form fields ticked, discarding hidden text also
takes the hidden text the flattened appearances bring onto the page,
which no scan before flattening counts, so with Flatten form fields and
Discard hidden text ticked, the hidden text was dropped from the list and
stayed in the file, where main removes it.
Every ticked category goes to remove_hidden again, as on main. When it
refuses (every category counts 0), it may have changed the copy (an
empty outline root goes with bookmarks, and then it refuses), so the copy
from before the call is kept and nothing is discarded. That also drops
the extra scan c7c018ac6 added.
Corrects c7c018ac6's message: remove_hidden counts first, then drops an
empty outline root, then refuses.

Before PDF 2.0, PRC in a 3D stream is an Adobe extension to PDF 1.7, so a
PRC model added to a file below 2.0 now declares /Extensions /ADBE at
BaseVersion 1.7, ExtensionLevel 1, keeping other extensions and a later
ADBE level, and leaving an /ADBE that is not a dictionary (an array of
them) alone (ISO 32000-2 §7.12). U3D and 2.0 files are unchanged.
A PDF poster whose page box has no area was drawn as nothing behind a
size forced to 1; it is now refused with EditError::Source.
Both found by CodeRabbit. Tests a_prc_model_declares_the_adobe_extension_before_pdf_2

A new `model_add` automation tool and `Edit::AddModel3d` embed a U3D or
PRC file as a 3D annotation (ISO 32000-2 13.6.2) in a chosen rectangle:
- The model goes into a Flate-compressed 3D stream (13.6.3) with /Type /3D
and /Subtype U3D or PRC, read from the file's header (`U3D` and a zero
byte, or `PRC`); anything else is refused before the document changes.
Models over 256 MiB (MAX_MODEL_BYTES) are refused. model_add checks the
file's size (from the file system) and its header before reading the
rest, so a large file that is not a model is never loaded; the path goes
through the read root, and `read_model` joins the helpers the
file-access test knows take a resolved path.
- /3DD references the stream, so the annotation has its own instance.
- /3DA states /A: click (XA, the standard's default and the tool's),
page_open (PO) or page_visible (PV).
- /AP /N is the poster readers print and show before activation: a chosen
image or PDF page fitted inside the box keeping its shape and centred (the
custom-stamp picture path: `mark_source`, `fit_picture`, and the stamp's
placement matrix now shared as `appearance::picture_place`), or, with no
picture, a light frame labelled "3D model". It is drawn in user space and
not counter-rotated, so on a page with /Rotate it turns with the page, as
the model does.
- /Contents carries the name (the file stem by default) as the alternate
description (12.5.2).
- A document older than the model needs gets /Version in its catalog
(7.7.2): 1.6 for U3D, 1.7 for PRC, as the optimizer does for JBIG2.
Adobe's extension level for PRC in 1.7 is not written.
- The 3D rectangle has its own MAX_MODEL_SIDE (14400 pt).
The edit is undoable ("Add 3D model"), needs the comments permission and
rebuilds only the comments view. A new parity entry, misc.3d-add, is
partial: no poster rendered from the model, no views (/VA, /3DV), no
replacing the poster, no UI command, no /Extensions. misc.3d-view is
unchanged. ROADMAP.md progress log line.

A soft mask is placed by the CTM in force when its `gs` runs (ISO 32000-2
11.6.5.2). The paragraph lifted over the scan re-selects the graphics state
after its own `cm`, so a mask selected before a translation landed
translated with it and could hide the new text. A re-emitted state that
carries a dictionary /SMask now records its anchor CTM and is selected
there: `cm` to the anchor, `gs`, `cm` back.
The test edits the same paragraph with and without a mask and requires the
same ink; it fails with the re-anchoring disabled (the mask lands 100 pt
right and the text vanishes). Both rewrite paths.

`ImageBudget::decode` is now the one public way to decode an image's
CCITT fax or JBIG2 data: `Document::decoded_image` and
`decoded_image_within`, which decoded with no limit on the work, are
test-only in pdfcraft-cos, and pdfcraft-filters exports only
`decode_ccitt_within` and `decode_jbig2_within`, which spend from a
caller's allowance (`decode_jbig2` is gone, `decode_ccitt` private).
So an operation over many images can't decode them without sharing an
allowance; the compiler holds new callers to it. Doctests that must not
compile check both crates; with the old entry points public they fail.
Tests outside the crates decode through an unlimited ImageBudget.
Streams in general (`Stream::decoded`) are left for a follow-up.
- Add Freehand-Highlight tool with 100pt line width support, Lucide highlighter icon, and PDF Multiply blending.
- Add customizable floating and docked hotbar with command picker, size slider, full-side strip chrome integration, and settings gear icon anchored at the bar end.
- Add left/right docking options for the navigation rail with toggle button and preferences setting.
The test timed the 100-field form three times, then the 800-field form
three times, and compared the best of each. A busy spell on a shared
runner that fell on the second half slowed only the large form, and the
ratio went past 16x (16.6x on a gate run) though it is about 7x.
Each of five rounds now opens the small form and then the large one, and
the best round's ratio is checked against the same 16x, after one
untimed opening of each. With the values filled one by one again (the
quadratic code before #4638) it still fails, at about 48x.
Document the existing policy: mixed plain and target-script text normalizes to that script, then to plain text, rather than reconstructing the original mixture. Undo restores exact prior text. Cover both scripts in engine and headless tool tests, including document-byte restoration, redo and save/reopen, and record the evidence in parity. The new tests pass against unchanged conversion logic; this is policy documentation and coverage, not a product behavior fix. Scoped Linux native, wasm, clippy, formatting, layers, assets and parity validation passed.

Each `Do` copied the page's `/XObject` dictionary, and each form its `/Resources`, `/Properties`,
`/Font` and `/ExtGState`, or the resources it was drawn with if it had none. So Office export of one
page took time in the square of what it drew: 31 s for 10,000 pictures, about 70 ms of it decoding, 30
s for 10,000 forms with no `/Resources`, and 16 minutes for one form with 100,000 keys in them drawn
50,000 times, in a test build.
`FormCall` keeps the form and `resource_dict` reads a dictionary where it is, with an object of its
own held. 10,000 pictures take about 0.15 s now, 10,000 forms 79 ms, and that form drawn 5,000 times 40 ms. The test holds to 10,000 pictures, not the 2,000 it could afford.
A `gs` reads a direct graphics state in place too, in the text walk and in `page_background`, and a
value of the wrong type isn't copied to find that out. A form that sets a font still reads the font each time it is drawn, as the fonts read
are kept only for that draw: 3.5 ms a draw for one of 100,000 widths.

the decoder's max_alloc limit still caps what decoding allocates. Its

Storing LZW streams with Flate decoded image streams outside the allowance,
with a limit for each stream and no total, and nothing asked whether to go
on: a 593 KB file of 100 images took 113 s with none refused, and images
refused by the image pass were still rewritten. The pass now pays for what
it decodes and for storing and checking it, at 8 steps a byte since Flate
takes up to 78 ns a byte, and streams past that stay LZW.
An image is counted as refused only when it stayed as it was: one packed
before the allowance ran out on its second read was rewritten. doc_reduce
reports images_refused as doc_optimize does, and the app's action says so
in its log. A refused image no longer reads as an unsupported filter:
FilterError::Spent says what happened.

From a review of who reads a refusal.
The rule is to leave it out and say so, and it held on some paths only. An image whose JBIG2 mask is
refused no longer comes out opaque. The first image past the allowance reads as that and not as
corrupt. A page reports what it left out. The Office warning stopped blaming forms. Redaction refuses
the run, leaving the document as it was: removing a readable image whole would take what no mark
covers with it, unreported.
The 2 GiB an export holds is twice the document if that is more, so a large honest file loses nothing.

One image has its own limit, about 6 s to 17 s, but nothing bounded a file of thousands of images
made to reach it: an operation took that long for each, and an image sharing /JBIG2Globals decodes
them again.
Image::decode_within (hayro-jbig2 patch 11) spends from what a run may still do, starting with its
page's pixels, and charge_reading charges reading a stream and its globals, 4 steps a byte, before
anything is parsed, so an image that fails has paid too. pdfcraft_filters::decode_jbig2_within takes
it, and ImageBudget in cos is that allowance: 2^34 steps, about 1,000 scanned pages, and 2^13 more for
each byte of the file, so a long scan is read whole. An image past it spends all that's left, and
later ones aren't read, globals included.
Optimize leaves such an image as it is and counts it in Report::images_refused. Image export leaves it
out, with the reason, and stops at 2 GiB of files held. Office export shares one allowance, leaves the
picture out and says the page was truncated. Redaction removes it whole, as any image it can't read.
Rendering gives a page's images 2^30 steps between them, inside the watchdog, and each page starts
afresh in Context::new as its other budgets do (hayro-syntax patch 31, hayro-interpret patch 73).
It's a thread-local, unbounded until a page sets it.

- Resolve all 13 merge conflicts between upstream/main and main
- Preserve full image editing suite: OBB, crop, proportional resize, arrange, and context menu actions
- Preserve text editing formatting tools: bullet/numbered lists, subscript/superscript, and line spacing
- Cleanly integrate upstream's canvas modularization, font updates, and styling changes
- Refactor arrange_image and run_edit_page_image helpers to satisfy clippy cognitive complexity limits
- All engine, edit, and UI integration test suites passing cleanly
From CodeRabbit's review of the stack:
- Every JBIG2 image read its /JBIG2Globals afresh, within 32 MiB each but with no
bound across an export or a redaction. A globals stream of the file, not edited since
it was read and with its /DecodeParms direct, now has its filters undone once a
document and is kept for the images that share it (in every clone, which share the
file), up to 64 MiB in all. An edited one, one added in memory, or one with
/DecodeParms by reference (another object, which can change under it) is read each
time as before. This saves the filters only: the decoder reads the segments afresh for
every image, so a real symbol dictionary still costs its decoding once an image.
- view.copy-image dropped "JBIG2 inside other filters" from its missing list on the
strength of Export's test; Copy Image now has its own: a JBIG2 picture behind
ASCIIHexDecode is found under the pointer and copied as its pixels and as a PNG, and
one whose page information is in its globals is read through them.
A JBIG2 image's /Width and /Height are read as given directly; one by reference is an
error rather than an image of no rows.
A /JBIG2Globals reference to no object still reads as no globals: it is a reference
to null (ISO 32000-2 §7.3.10), which an entry may hold for being absent (§7.3.7), and
the renderer draws the page so. An image that needed those globals then mostly fails
to decode; in a probe of twelve pictures that decoded with them, eleven were refused
and one decoded to other pixels.

Conflict in crates/edit/src/text_regions/styled.rs: kept this branch's
`row_step` beside main's `WrappedStyledRows`, and main's marker-aware
`splice_with_marker` splice with the branch's `at` (already computed
before the reach check). main's `wrap` now yields (line, soft, gap), so
the reach's widest line in rewrite.rs reads the line from the tuple.
Gates: fmt, clippy -p pdfcraft-edit -p pdfcraft-engine --all-targets
-D warnings, tests edit 362 / engine 388 / 18, xtask parity.
