alloc_id bumped next_id with saturating_add: a presentation whose
next_id reached u32::MAX (a hostile file can arrive that way;
fix_next_id imports it) handed out that same id to every new slide,
shape, layout and media - duplicate ids, ambiguous references, silent
corruption on every later insert.
alloc_id now returns Option<u32> via checked_add, and every caller
refuses: the engine's insert/duplicate/media/layout commands answer
with a clear error naming the command, paste and duplicate re-id
helpers propagate it, media addition is fallible, and a fresh slide is
Option. The pptx export's synthesized blank layout is guarded the same
way. Loading keeps such a deck viewable: repair re-ids duplicate
slides while it can, and a duplicate it cannot re-id stays as it is -
growth is refused, and only that duplicate keeps its ambiguous id.
Renumbering the loaded graph was rejected: it needs the
cross-document reference remapping that issue #406 tracks.
Tests: model exhaustion (alloc_id None, fresh media refused, a new
slide refused), engine (slide.new, shape.insert, slide.duplicate and
edit.duplicate all refuse; the document holds no duplicate ids),
format repair (an unre-id-able duplicate stays visible).
* Engine: file.info and PowerPoint-style print slide ranges (#76)
file.info reports what File › Info shows (name, path, format, unsaved
changes, slide and hidden-slide counts, sections, size on disk,
properties). file.export's PDF `slides` also takes the range typed in
PowerPoint's Print page ("1-3, 5", 1-based); bad or out-of-range text is
an error instead of a silent full export.

* UI: the File tab (Backstage) like PowerPoint's (#76)
File (first ribbon tab) or Alt+F opens a full-window view in place of the
ribbon, slides and status bar: a side menu (Back, Home, New, Open, Info,
Save, Save As, Print, Export, Close; Account and Options at the bottom)
and the chosen page. Esc or Back returns; Up/Down walk the side menu and
show each page as it gets the focus; Enter runs Save/Close/Options.
Laid out after PowerPoint for Windows as observed: 160-pt menu a step
darker than the page, outline icons, current page in the accent colour.
The start screen is now File › Home (as in PowerPoint), with only Home,
New and Open at the top and no Back. Pages call existing commands and
file helpers: file.new {theme} and the sample deck (Home, New); recent
files with search, Browse and Recover Unsaved (Open); file.info and
file.properties, Accessibility Checker, Revert (Info); file.save /
file.saveAs / file.export by type (Save, Save As); a PDF with the Print
page's slides, layout (full page, notes, handouts 1-9), hidden slides and
frames, opened in the system viewer or downloaded on the web, with a
page preview (Print, Ctrl+P); Create PDF, Create Handouts and Change File
Type (Export); appearance and About (Account); Preferences (Options).
Share (cloud) is left out.
Close and Ctrl+W now ask Save / Don't Save / Cancel about unsaved
changes instead of closing at once. The Export dialog shares
SlideApp::export_as with the Export page. New UI commands: app.backstage
{page}, app.closePresentation, app.print; ui.inspect reports the page.
New icons drawn in code: back, save as, account, recent, new file, open
folder.

* 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.

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.

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.
