slide.reuse indexed src.slides[i] and found media by scanning JSON keys
(media/poster/preview/sound), which missed artistic-effect originals and would
miss any reference stored under another key. New engine module media_refs: one
typed walker over the model (written once, expanded for & and &mut) that visits
every MediaId a presentation, master, layout, slide or shape can hold: pictures
and their artistic originals, picture fills in shapes, lines, runs, table cells
and styles, chart series and points, backgrounds and theme format schemes;
media clips and posters, 3-D models, OLE/SmartArt previews and node pictures,
picture bullets, hyperlink, transition and animation sounds, embedded fonts.
slide.reuse now lists and remaps media through it, uses get() for slides, and
keeps a linked media item's link when copying it.

Undo kept up to 500 steps whatever their size. Steps share what an edit didn't touch, so most
are small, but a deck-wide edit (slide size, theme, find-and-replace style changes) keeps a copy
of every slide: 500 of those on a big deck could hold hundreds of copies. Each step's cost is now
estimated when it is pushed (the slides, masters and media it doesn't share with the document
after it), and the oldest steps are dropped while the total passes History::byte_limit
(UNDO_BYTE_BUDGET, 256 MiB, by default). The newest step always stays.

- ui.json / prefs.json are read through a new settings module: regular files only, 4 MiB
cap, parse errors logged, values sanitized (a saved zoom of 1e30 aborted start-up,
1e4 panicked in egui); writes are atomic.
- The canvas and the control protocol clamp stray zooms; the status bar shows the zoom in use.
- The canvas texture is cut to the GPU's max texture side (zoom 400% on a 2048 limit panicked).
- The system font scan opens only regular files of sane size (a FIFO named *.ttf in ~/.fonts
hung start-up), with depth and entry caps.
- AutoRecover skips non-regular entries and reopens at most 32 per start, newest first.

Insert › Icons places seventy Lucide 1.56.0 stroke icons as custom
geometry: no fill, round caps, and a line width scaled from the
24-unit design. The gallery searches by name. SVG paths, including
arcs, are converted when the icon is inserted so the renderer strokes
the outline.

File › New and the start screen offer Briefing, Lesson, Pitch, Field Notes,
Quarterly and Evening Talk. Each is a few slides of our own text on one of
our themes. file.new takes template, and file.templates lists them. Passing
a theme as well, or blank, is refused. PowerPoint's large gallery is still
open.

View ▸ Notes Master edits the notes master on a notes-size page (creating
PowerPoint's default placeholders if the deck has none); its tab toggles
header, date, slide image, body, footer and page number, sets the
background and closes the view. The PPTX writer now writes an edited
notes master as it is, even in a deck without notes. Stacked on #572.
View ▸ Handout Master opens the handout master (creating one with header,
date, footer and page-number placeholders if the deck has none) on a page
at the notes size, with a dashed preview of where 1-9 slides go. Its
contextual tab toggles the placeholders, sets the background and closes
the view. Stacked on #533, which reads and writes the handout master.
Adds edit.pasteSpecial. Keep Source Formatting bakes the copied shapes'
theme colours and theme fonts into fixed values (captured at copy time),
Picture draws the copied shapes into one PNG picture, and Keep Text Only
pastes plain text. Ctrl+Alt+V, Edit › Paste Special… and the Paste menu
open a Paste Special dialog.

Review > Thesaurus (Shift+F7) opens a Thesaurus pane on the selected
word, or on the word at the caret. Clicking a synonym while editing
text puts it in place of that word in one undo step, and the pane
then looks up the new word. You can also type a word into the pane to
look it up.
The word list is written for DeckCraft and has no third-party source:
about 260 senses of common presentation vocabulary in
engine/data/thesaurus.txt. It is embedded, so the Thesaurus also
works offline and in the browser build. Lookups try simple English
endings and keep the word's capitalisation. New commands:
review.thesaurus (a query) and review.replaceWord. Ribbon big buttons
now carry an accessibility label.

Insert > Table > Draw Table turns on a table pencil. Dragging a box on an
empty part of the slide makes a one-cell table. Drawing a line inside a
table splits the cells it crosses, across or down, and adds a row or
column only where needed, so the cells it doesn't cross stay whole.
Table Design > Draw Borders has the pencil and a Table Eraser. A click
on a border merges the two cells on either side when together they
form a rectangle, and their text is kept.
The new table.drawLine and table.eraseLine commands are each one undo
step. The grid work is pure (engine/src/drawtable.rs). It rebuilds the
table from its anchor cells, so existing merges survive, and it caps
the grid at 200 rows and columns. Ribbon big buttons now carry an
accessibility label.

Draw > Ink to Shape recognises each pen stroke on the slide's ink layer
as a line, rectangle, oval or isosceles triangle (apex up or down) and
replaces it with that preset shape, outlined in the stroke's colour and
width with no fill. Strokes it can't recognise, and highlighter strokes,
stay ink. The ink shape is removed once it has no strokes left. The
whole conversion is one undo step.
The recogniser (engine/src/inkshape.rs) is pure geometry: ends meeting,
area covered within the bounding box, and spread from the fitted
ellipse. Ribbon big buttons now carry an accessibility label.

review.compare {path | name, data} reads a revised presentation (native or
PPTX) and lists slide-level revisions against the open one: inserted,
deleted and changed slides, with what changed (text, text formatting,
moved, resized, rotated, formatting, picture, objects inserted/deleted,
layout, notes, transition, animations, background, hidden). Slides match by
id, or by position when the decks share none (fixed for the session so
accepting doesn't switch the matching half way). Shapes match by id, then
name.
review.accept {index | all} applies revisions as one undo step: a revised
slide's media is copied (remapped on an id clash), its shape ids kept unless
another slide uses them (animations follow), its layout matched by id, then
name. review.revisions and review.endCompare complete the set.
Review tab: Compare (file picker), Accept All, End Review; the Revisions pane
lists changes with Go-to and Accept. Parity row: Compare presentations M → P.

AutoCorrect gains PowerPoint's options: correct TWo INitial CApitals,
capitalize the first letter of sentences and the names of days, fix
accidental cAPS LOCK, and replace 1/2, 1/4, 3/4 with fraction
characters. "word..." becomes "word…", "word," and "word." are corrected
too, and the built-in list grows from 13 to ~70 entries. The case rules
apply only to typing, not pasted text.
New text.autocorrect sets the options and adds or deletes replace
entries (your own win over the built-in list; deleted built-ins stay
deleted) and returns the list. Preferences ▸ AutoCorrect Options… opens
an AutoCorrect dialog with the options and the editable list.

Follow-up to the transition sound picker. The Sound box now lists
[Stop Previous Sound] and six built-in sounds (Chime, Click, Camera,
Whoosh, Drum Roll, Laser) that are synthesised as small WAVs when
chosen, so no sound files ship with the app; the same built-in sound is
embedded once however many slides use it. Loop Until Next Sound repeats
a sound in the show until another slide's sound or Stop Previous Sound.
PPTX reads and writes p:stSnd loop="1" and p:endSnd, keeps the sound's
file name in p:snd/@name, and setting a slide's transition to None no
longer drops its sound.

ui_soak_tests.rs drives the app through the egui test harness with seeded
random clicks, drags, keys (plain, Ctrl, Shift), typing and scrolling over the
sample deck. Every ten actions it checks that every document validates, the
selection is in range, undo, journal, thumbnail and texture caches stay
bounded, and no command or render panic was caught; at the end, that input
really reached the editor and the mean frame stays under 250 ms. Two seeds x
150 actions run in CI; DECKCRAFT_UI_SOAK_STEPS/SEED run it long.
Panics swallowed by the guards were invisible to tests: Session now counts
them (panics_caught) and deckcraft_render::panics_caught() counts render
panics drawn as blank. Textures::thumb_count exposes the thumbnail cache size.

soak_tests.rs drives every non-file command with plausible and hostile
parameters over a ~100-slide deck, checking after each step that the
document validates, the selection is in range, the undo stack is bounded,
undo then redo restores the exact document, and every 100 steps that the
deck saves and reopens as .deckcraft and .pptx. Four seeds x 400 steps run
in CI (under a second); DECKCRAFT_SOAK_STEPS/SEED run it long.
The long soak found that a chart a few points wide panicked in f64::clamp
(label gutter min above max), and the render guard then blanked the whole
slide. chart.rs now uses a non-panicking clamp_soft for the gutters and the
zero line; a render test draws tiny charts next to a shape without the
guard.

Document uids started at 1 in every process, so two instances sharing
the recovery folder overwrote and deleted each other's entries, and
file.recovery.open deleted each entry as soon as it was loaded, leaving
nothing if the app died before the next checkpoint.
- Uids are a random per-process base plus a counter (below 2^53).
- Each instance holds a lock on owner-<id>.lock in the folder; entries
record their owner, and recovery open skips a running owner's entries
and removes stale lock files.
- Opening an entry no longer deletes it: the recovered presentation keeps
the entry's uid and takes ownership, so the snapshot stays until the
next recovery save replaces it or a save/close removes it.
- Entry files and metadata are both written via temp file + rename.

* Text: Ctrl+arrows, Ctrl+Backspace/Delete and the other text keys work like PowerPoint (#268)
Observed black-box in PowerPoint for Windows on synthetic text:
- Word stops (crates/model/src/words.rs): words, punctuation runs, symbol
runs, tabs, line breaks and each CJK character are tokens; trailing spaces
join the token before. it's, a-b, 3.14, 1,000 are one word; e.g., a_b and
x@y.com are not. Grapheme clusters never split.
- Ctrl+Left/Right and Ctrl+Shift+Left/Right move by those stops, across
paragraphs; with a selection they go on from its start/end. In a
right-to-left paragraph Left and Right swap.
- Ctrl+Backspace deletes to the previous stop; Ctrl+Delete deletes the rest
of the word, or spaces plus the next word, then applies PowerPoint's smart
spacing. With a selection both work from its start.
- Ctrl+Up/Down by paragraph, Ctrl+Home/End to the text's ends.
- End on a wrapped line goes past the trailing space and the caret stays
drawn at that line's end (TextSel::line_end); End again stays, Home
returns to the same line.
- Ctrl+]/[ and Ctrl+Shift+>/< change font size (egui's Period/Comma/
bracket key names now match registry shortcuts).
- Shift+F3 cycles lower -> Title -> UPPER; a caret changes its word.
- Double-click selects the word without trailing spaces; triple-click
includes the paragraph mark.
- Mac keeps Option for words and Cmd for line/text ends (Session::mac_keys).

* Text: input method composition as commands, one undo step per composition (#101)
text.compose shows an input method's preedit in place at the insertion point and replaces it on
each update; an empty preedit cancels and restores the text and selection. text.commit replaces
the composition with the result as one undo step. Any other edit, key or click settles an open
composition first. The composition is underlined under the baseline (thicker under the part being
converted), and the caret line is measured for empty placeholders too.

* UI: Korean, Japanese and Chinese input and interface text (#101)
The slide turns the input method on while it takes typing, with the candidate window at the
caret, and forwards egui Ime events to text.compose / text.commit, so a Korean keyboard composes
syllables instead of separate jamo. Interface text in scripts the interface fonts lack (Hangul,
Simplified Chinese, Thai...) borrows faces from the font database (installed fonts such as Malgun
Gothic; nothing bundled): file names, titles, notes, outline, sections, comments and typed text.
Ported and widened from WordCraft's #565/#840 fallback. The notes pane keeps text typed before
focus leaves in the same frame (Escape, another slide). Control channel: ui.ime.

* feat(pictures): animated GIFs play, with pause (media.gifPlay)
GIF pictures used to show only their first frame. The renderer now decodes every frame (cached, capped at 256 MB and 1024 px a side) and draws the frame for each GIF's play time, passed in RenderOpts::gif_times; exports and thumbnails pass none and keep frame 1. The editor canvas and the slide show redraw only when a GIF reaches its next frame. A corner button on hover (or selection) pauses and resumes a GIF from the same frame, through the new media.gifPlay command.
