PowerPoint draws normAutofit text at its saved fontScale/lnSpcReduction;
we ignored them and only shrank when our own layout overflowed, so saved
decks showed larger text and wider line spacing than PowerPoint, with text
running past placeholders. The layout now starts from the saved scale
(nonsense values ignored) and still shrinks further when the text doesn't
fit. Editing the text resets the saved scale so the new text is fitted
afresh, as PowerPoint refits on edit.
File ▸ Open's Outline filter accepts `.md`, but a `.md` was read with the
plain outline format (unindented line = slide, indent = bullet), so a
Markdown outline written the usual way kept `#` in its titles and made
every top-level list item a slide of its own.
`deckcraft_format::markdown_to_slides` reads ATX headings (`#`–`######`,
closing `#`s dropped) as slide titles, list items (`-`, `*`, `+`, `1.`,
`1)`) as bullets nested by their indentation, and other lines under a
heading as body paragraphs. A `.md` without headings is still read as a
plain outline, so existing indented `.md` outlines open as before; `.txt`
is unchanged. Opening a `.md` and dropping one on the window
(`slide.fromOutline {markdown: true}`) use it. Both readers now share the
slide builder.
Tests: the outline from the issue (2 slides, nested bullets), numbered and
`*`/`+` lists with text under a heading, `slide.fromOutline` with
`markdown`, plain `.txt`/`.md` outlines unchanged, and heading / list-item
edge cases (not-a-heading forms, closing hashes, Unicode, long digit runs).

Saving with a .potx or .ppsx name wrote a byte-identical .pptx: the
main part was always presentationml.presentation.main+xml, because
format_for_path folded all three extensions into "pptx". It now keeps
potx/ppsx, and deckcraft_pptx::export_as picks the template or
slideshow content type.

The Slide Size dialog gets an Orientation choice that swaps width and
height, and design.slideSize takes orientation: portrait|landscape so a
preset can be made portrait from the CLI and MCP too.

The current slide stays put and any shape or text selection is cleared. A scope other than slides is an error; without a scope the command still selects shapes.
There was no way to turn a presentation into an animated GIF. file.export now writes one: format
`gif` (or a .gif path), one frame per slide drawn by the slide renderer and shown for
secondsPerSlide, encoded with the `image` crate's GIF encoder (already a dependency, no new
crates) with a 256-colour palette per frame: exact when a slide has 256 colours or fewer,
NeuQuant otherwise. Slides are composited onto white.
Options: width (small 640, medium 960 (default), large 1280, extraLarge 1920, or 16-3840 px; the
height follows the slide's aspect ratio, no side over 3840), secondsPerSlide (0.1-600, default 5,
written in GIF hundredths), loop (forever by default, or once: no NETSCAPE2.0 block), slides (a
list of indices, in play order) and includeHidden (hidden slides are skipped by default).
Out-of-range or wrongly typed values, NaN and infinities are BadParams errors, never panics; at
most 500 frames and 200 million pixels in total, checked before anything is rendered.
- Engine: crates/engine/src/gif_export.rs (options, frame list, size, encoder);
cmd::file::gif_bytes, save_bytes("gif"), format_for_path(".gif").
- UI: the Export… dialog (Command palette; the app has no File menu yet) gets "Animated GIF (.gif)" with Size, Seconds per slide, From/To slide,
Loop forever and Include hidden slides; an invalid range or value keeps the dialog open with a
message. The web build downloads the bytes (image/gif).
- CLI: convert IN OUT.gif, run --export OUT.gif --export-params JSON; usage lists the format and
options.
- MCP: the export tool lists gif and width/secondsPerSlide/loop (slides and includeHidden now
apply to PDF and GIF).
- Docs: file-format parity GIF row, gaps (video export remains), parity checklist row M -> P
(P2 breadth 36% -> 37%, overall 79%), control protocol, MCP, README, ROADMAP progress log.
Transitions and build animations are not animated in the GIF (tracked with video export).

When typing in Kurdish, Arabic or Hebrew in a new document or text shape, default
paragraph direction (props.rtl: None) was resolving to LTR. In an LTR
paragraph, visual reordering pinned newly typed characters and the caret to the
left margin, resetting to the start of the line with every keystroke and jumping on
space characters due to UAX #9 rule L1.
- Add first_strong_is_rtl() in deckcraft-model following UAX #9 rules P2/P3.
- Auto-resolve unassigned paragraph direction to RTL in shape_para layout when the
paragraph starts with an RTL script, defaulting alignment to Align::Right.
- Auto-promote paragraph to RTL (props.rtl = Some(true), props.align = Some(Align::Right))
when typing or inserting text starting with an RTL character.
- Add regression tests in deckcraft-model, deckcraft-text, and deckcraft-engine.
Notes from a .pptx were read and written with their formatting, but the notes pane and Notes
Page drew them as plain text (Slide::notes_text in a plain TextEdit), and any edit there saved
the text back through slide.notes as TextBody::from_text, dropping every bold run, level,
indent and bullet of the slide's notes.
- ui-egui: a notes editor (notes.rs) shared by the notes pane and Notes Page. It draws bold,
italic, underline, strikethrough and size from the runs, and each paragraph's margin, hanging
indent and bullet or number (Wingdings/Symbol bullets mapped as on slides); paragraphs are
laid out one by one so wrapped lines align with the text, not the bullet. Each edit is applied
to a formatted draft, so typed text takes the formatting where it lands (Enter in a bulleted
point starts another), and the draft is saved once the field loses focus or the slide changes.
- engine: slide.notes takes `body` (formatted notes, as slide.inspect's new `notesBody`), and
`text` now changes only what was retyped (model edit::replace_text); text sharing nothing
with the old notes is still plain.
- text: map_symbol_bullet is public for the notes editor.
PDF notes pages still print the notes as plain text.

A shape id that was present but not a valid id (negative, not an integer,
larger than u32) was treated as absent, so commands such as text.set and
text.edit silently edited the selected shape instead. id_param now tells three
cases apart: absent (the selection fallback is unchanged), valid, and invalid
(an error naming the command). arrange, edit (select), inspect, review, table,
text and the animation painter pick this up.
slide.go clamped an out-of-range index to the last slide and reported
success, so a request for slide 99 of a short deck landed on the last slide
without a word. It now returns an error and stays on the current slide. A slide
id beyond u32 is reported as an unknown slide instead of being read as id 0.
file.export with an explicit format outside png, jpeg, jpg, pdf, pptx, potx,
ppsx, deckcraft, outline and txt fell through to the native deckcraft zip, so a
request for "docx" reported success and wrote a deckcraft archive under that
name. It now returns an error and writes nothing. A format inferred from the
file extension behaves as before.
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.
