* 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).

* #133: Selection pane engine: restack inside groups, Show/Hide All, Lock like PowerPoint
- arrange.bringForward/sendBackward/bringToFront/sendToBack and arrange.reorder work on a
group's children, which stay in their group (as PowerPoint's pane arrows and drag do);
steps that change nothing leave no undo step.
- selection.select (pane click: Ctrl toggles, children and top-level objects don't mix,
picking a hidden object shows it), selection.showAll (everything, children too) and
selection.hideAll (top level).
- shape.lock cascades through groups; locked objects can be selected, formatted and typed
in, but not moved, sized, rotated, flipped, reshaped or cropped (commands and canvas).
- PPTX: Lock reads and writes PowerPoint's full locking attribute set per element kind
(observed by saving locked objects from PowerPoint); partial locks aren't Lock.

* Front-most first with groups folding; drag a row to restack among its siblings (accent
insertion line); Bring Forward / Send Backward arrows; Show All / Hide All; per-row eye and
padlock; double-click or F2 renames in place; Ctrl+click toggles, Shift+click selects a run;
arrows, Home, End and Esc in the list; right-click menu. Lock/Unlock on the canvas menu,
greyed handles on locked objects. egui_kittest tests drive the pane.

* 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.

PowerPoint's Normal view draws shapes, pictures and text that sit partly
or wholly off the slide on the area around it, at full strength, with
their effects, master and layout graphics included; the slide show,
exports and thumbnails clip to the slide. DeckCraft clipped everything to
the slide in the editor too.
- render: `slide_extent`/`layout_extent` estimate how far a slide's
drawing reaches (boxes, outlines, shadow, glow, reflection);
`render_slide_drawn` also reports what a render actually drew (text
spilling out of its box, table rows that grew); `pasteboard_region`
picks the pixels the editor renders: the slide plus what reaches off
it and is in view, rounded to 256 px tiles so scrolling rarely
re-renders. A slide with nothing off it renders exactly as before.
- ui-egui: the canvas texture covers that region (slide and master
views); it re-renders only when the slide, zoom or the region changes,
and a second time only if text drew beyond the estimate.
- Hit testing, selection, marquee and moves already worked in slide
space; tests now cover them off the slide.

Theme background pictures (Office 2007-era themes such as Treck) carry an
a:duotone recolour in phClr; DeckCraft read it but drew the picture
unchanged, so those backgrounds came out grey. The painter now resolves the
duotone's colours against the slide's colours and placeholder colour, and
the decoded-image cache applies them (luminance picks a colour between dark
and light) and keys on them.
Layouts and slides can replace the master's colour map
(p:clrMapOvr/a:overrideClrMapping, e.g. dark section layouts mapping bg1 to
dk1). They were read as the master's map; now Layout and Slide carry an
optional colour map, resolve::Ctx uses slide > layout > master, and the
writer keeps them.

Every datetime field showed the deck-wide fixed date text instead of a date: empty when no slide
had a fixed date, and that text on every slide when one did. A fixed date is plain text in its
slide's placeholder; a field is an automatic date, so it now shows the local date and time in the
format of its type (ECMA-376 datetime1 to datetime13 as PowerPoint lists them for English,
datetime and datetimeFigureOut the short date). Numeric dates follow the run's language
(en-GB 09/10/2026, de-DE 09.10.2026...); formats with names stay English-only, so other languages
keep the field's saved text, as do unknown types and builds without a clock (wasm). The saved
text is kept on save.
- text: datetime module (field types, formats, local clock via chrono, not on wasm);
Fields::field_in passes the run's language.
- render: RenderOpts::now injects the clock (tests, deterministic output); the PDF text layer
uses the same fields.
- engine: Header & Footer turns existing date placeholders into fixed text or back into a
field; new date fields are saved with the date they show (local, not UTC).

Three causes, each making links look like they "don't save":
- With the caret at a word boundary (end of text, empty paragraph),
insert.hyperlink formatted an empty range and changed nothing. It now
inserts the address (or the slide's title, or `text`) as linked text, as
PowerPoint does. Typing right after a link no longer extends it.
- The slide show ignored hyperlinks and shape actions. A click on one now
follows it (ShowState::follow): slides, next/previous/first/last, Last
Slide Viewed, End Show, and URLs; the pointer turns into a hand over links.
- The desktop app was built without eframe's `links` feature, so
ctx.open_url did nothing natively (also the ribbon's app page link).
Enabled as in DesignCraft, EffectCraft and PrintCraft.
Saving was fine: links round-trip through .deckcraft and .pptx.

* 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.

* Animated GIFs: cap frames (1000), canvas (4096²), per-GIF (64 MB) and cache (192 MB) memory
A few MB of hostile GIF could decode to millions of tiny frames or a 100 Mpx canvas per frame,
and eight cached GIFs could hold 2 GB.

Flips mirror a shape's geometry, never its text. The text was drawn with the shape's full
transform, so every label on a flipped arrow came out mirrored (flipH) or mirrored upside down
(flipV). As in PowerPoint, the text rect keeps its flipped place and the text is mirrored back
about the rect's centre: flipH text stays upright, flipV (or both flips) turns it 180°, rotation
still applies, and the same holds for shapes inside flipped groups.
render::text_transform is that transform (plus vertical-text rotation). Drawing, the PDF text
layer and link boxes, morph text, the editing caret and selection, and click-to-place-the-caret
all use it, so a click lands on the character drawn under it.

Text with a:hlinkClick (to a URL or a slide) looked like the text around it. As in PowerPoint,
a linked run now takes the theme's hlink colour and a single underline, unless the run itself
sets a colour (PowerPoint 2019 and later honour it) or an underline (u="none" removes it).
Colours from list and master styles don't count, so links in titles are blue too.
This is part of run resolution, so links added with insert.hyperlink look the same, Format
shows them underlined, and turning underline off writes u="none". The run's own props are left
alone, so the look follows the theme.

* Fonts: the bundled script face comes before installed fonts; no Microsoft family names
Arabic, Hebrew, Thai and Devanagari clusters try the craft-fonts face first, so every machine
draws the same, then openly licensed or OS-native installed families, then any installed face.
Installed Microsoft faces are still used through that scan, but not named (AGENTS.md §1.1).

* Tables: rows grow to fit their text, cell text in the PDF text layer (#13)
A stored row height (a:tr/@h) is a minimum, as in PowerPoint: each row grows so its cells' text fits. Tables from pandoc or python-pptx store h="0" and drew every row on top of each other. Cell editing (click to edit, cell outline) uses the same heights, and the PDF text layer now includes table cell text.
* Tables: a grown table's box covers its drawn rows; resize scales from drawn heights
Handles, hit tests and marquee used the stored frame, so rows grown to fit their text drew
below the selection box (a file with h=0 rows had a 0 pt tall box). Resizing divided by the
stored row total, which is ~0 for those files.
