Long speaker notes grew out of the notes pane and over the slide: the
editor now scrolls inside the pane. In Presenter View the Previous, Next
and End Show buttons drew dark text on the dark window, so they looked
missing; they are now light on a visible fill, and the timer gets Pause /
Resume and Reset.

AppKit draws the traffic lights 16 pt from the top of the window on macOS 27,
but the title bar was 38 pt, so they sat above its centre line. On macOS the
bar is now 32 pt, centred on them: content starts after the lights with the gap
they keep from the top, and the Present button shrinks to 22 pt to keep a
margin. Same approach as wordcraft #255 and gridcraft #323, with the light
metrics measured on macOS 27. Linux, Windows and web are unchanged.
Exit effects DeckCraft had no entry for (Peek Out, Strips, Blinds, Box,
Checkerboard, Diamond, Sink Down, Spinner, Contract) imported as a plain
Fade and lost their direction, so a Peek Out or Sink Down didn't move.
Each mirrors an entrance DeckCraft already plays, so it is played as that
entrance in reverse (Sink Down as Rise Up, leaving downward); the import
keeps PowerPoint's direction and saving writes a matching filter or
motion. Float Out now also writes its motion.
The preset ids and directions come from PowerPoint: every effect, as
entrance and exit, in every direction it accepts, saved and read back.

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).

The writer named a preset's only guide `adj` whenever the preset has one
adjust value, but bentConnector3, curvedConnector3, frame, mathPlus,
mathMinus and mathMultiply call it `adj1`, and PowerPoint refuses to open
a file that renames it. The names come from PowerPoint itself: every
autoshape and connector created with an adjusted first value and saved;
these six are the only single-guide presets named `adj1`.

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.

A legacy OLE object finds its preview in the slide's VML drawing through
spid; DeckCraft doesn't write that drawing, and PowerPoint refused to
open a file whose oleObj has a spid but no VML shape. The reader now
takes the preview picture from the VML drawing (so DeckCraft shows it
too), and the writer drops spid and adds that preview as a p:pic, the
form PowerPoint itself writes as the fallback.
Checked in PowerPoint: the issue's 45545_Comment.pptx saved by DeckCraft
opens with its three embedded objects and draws slide 8's table.

An object DeckCraft doesn't model kept its XML, but the parts that XML
points to (diagram data, layout, style and colours; an OLE embedding)
were not kept, so a save wrote it as an empty rectangle or its preview.
Opaque now carries those parts (relationship id, full relationship type,
the part as a media item) and the writer re-adds them under the slide's
new relationship ids. A part with relationships of its own, or an
external link, still falls back to the preview with the existing
warning. A diagram's data part loses its link to the cached drawing,
which is a slide relationship id a save renumbers; only diagrams whose
drawing is missing or empty reach this path.

The Picture Format ▸ Change Picture button ran the insert-picture dialog,
so it added a second picture instead of replacing the selected one. A new
app.changePictureDialog picks a file and runs picture.change, which keeps
the picture's position, size and formatting; the canvas right-click menu
offers it on pictures too. On the web, where the file arrives later
through the inbox, the pending change is remembered for that pick.

The UI remembers whether the last press landed in the thumbnail pane (the sorter always counts) and passes scope slides to edit.selectAll in that case.
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.
egui-winit drops Ctrl+V when the system clipboard is empty. Copying a
rectangle or picture puts no text on it, so the shortcut never reached
the session and only the context menu could paste objects. Copy and cut
now leave an invisible word joiner on the system clipboard in that case,
and paste maps it back to the session's own clipboard.
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.

The value axis used a generic "nice" scale: about five intervals and no
headroom, so data with a maximum of 42.1 got 0-50 in steps of 10, while
PowerPoint and LibreOffice draw 0-45 in steps of 5.
`auto_scale` now follows the rule Office documents for automatic limits:
the maximum is the first major unit at or above max + (max - min)/20, the
minimum is zero when all values are positive and the smallest is below 5/6
of the largest (otherwise the first major unit at or below min - the same
headroom), and all-negative data mirrors that. The major unit is the
smallest 1, 2 or 5 x 10^n that gives at most 10 intervals. Fixed
`<c:min>`/`<c:max>` limits are kept as they are and no longer get rounded
or padded; values beyond them stop at the plot edge. 100% charts get
0-1 in steps of 0.1.

Ctrl/Cmd + wheel and pinch changed the zoom but left the scroll offset
alone, so the slide grew from the canvas corner (from its top-left once it
was larger than the window) and the spot under the pointer slid away. The
pointer position was read but never used. Zoom In/Out, the status-bar
slider and the Zoom dialog had the same effect.
The canvas now remembers last frame's slide rect and scale. When the scale
changes it sets the offset so the slide point under the anchor stays put:
the pointer for wheel and pinch zoom, the middle of the canvas for the
commands. Once the slide fits the window it is centred as before. Wheel
and pinch zoom take effect in the same frame instead of the next.

PowerPoint 2021/2024 write a 0.5 s transition with neither spd nor
p14:dur, since "fast" is the schema default for spd. The reader fell back
to the effect's own default instead (Morph 2 s, Fade 0.7 s, most 1 s).

PPTX import already read PowerPoint's media effects (presetClass
mediacall: Play, Pause, Stop) into the timeline, but the show never
carried them out: media started only with autoplay or a click on it.
The show now sets off a step's media effects as the step reaches them,
and also when a click cuts the step short.
A step also no longer lasts as long as the media it starts: the video
plays on by itself and the next click goes on at once. An After Previous
effect behind it still waits for the media to end.

The engine handled Tab (a tab character, or a list level at the start of
a paragraph), but egui also treated it as focus navigation: with no
widget focused it focused the first ribbon widget, and since the slide
only takes keys while nothing is focused, every key after Tab was lost.
When the slide has the keyboard, the keyboard handler now cancels that
focus move.
This also covers the "can't type after indenting" part of #93.

Two paired pictures that differed only in crop counted as changed
content, so the new one faded in over the old one on the moving box.
Now they stay one picture whose crop morphs: the whole image moves and
scales linearly between where it lies on either slide, and each frame's
crop is what the interpolated box shows of it (morph_crop).

The last matching pass paired any two shapes of one kind and preset
geometry, so a text box leaving the slide was paired with an unrelated
one arriving and flew across to it. That pass now only pairs shapes
without text: a text box needs its name or its text on the other slide
to morph, otherwise it fades out (or in) where it is, as in PowerPoint.

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.
Two threads resolving a family nobody had loaded yet raced. The one that
lost the race saw add_font add nothing and fell back to another face, and
a lookup made while a family was being added saw only part of it (Arial
Bold Italic loads first, so "Regular" came back bold italic). The same
text was then laid out in different fonts depending on timing, which made
clicks_in_flipped_shapes_hit_the_text_where_it_is_drawn flaky when the
theme font isn't bundled.
Loading installed fonts now happens under one lock and rechecks once it
holds it, and a family's faces are added in one step.

Follow-up to #27. render_blend built a GeometryMorph (contours, alignment)
for every morphing shape on every frame, though only t and the current box
change while a transition plays. The Renderer now keeps the aligned morphs,
keyed by both geometries and their own sizes, and drops those a frame did
not use, so the cache ends with the transition.
- render: morph_path::Cache replaces morph_path::geometry; blend sweeps it.
- test: one alignment per transition, same geometry as a fresh one.

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.

A corner button on hover (or selection) pauses and resumes a GIF from the same frame, through the new media.gifPlay command.

It ran file.new, so each click silently added another blank presentation

shows the start screen over the open presentations, with a "Back to …"

from it leaves it. While it's open, keys don't reach the hidden

them (color_grid calls ui.close()), and the other buttons in them

* Morph: a changed geometry morphs its outline (a circle turns into a star)
Paired shapes that differ only in geometry (another preset, other adjust
values, a custom path) and fill colour no longer cross-fade: one shape moves
and its outline turns from the old geometry into the new one.
- geom::morph aligns two outlines the way manim does: the same number of
contours, the same number of cubic curves per contour pair, then every
point moves in a straight line. Closed contours are turned and reversed so
the points travel least (a triangle does not twist into a circle), extra
points go to the longest curves, and a sub-path without partner grows out
of (or shrinks into) a point, so a cube's faces appear and a donut's hole
closes. Fill mode, outline and fill rule switch at the midpoint.
- anim::morph_frame lists such shapes in MorphFrame::paths; the renderer
draws them with the morphed geometry (PathMorph, a new render_blend
argument next to TextMorph).
Ported from the path morph in alexplain (MIT, same author).

* Morph: differing looks of an outline cross-fade instead of switching
When a sub-path pair differs in fill mode, outline or fill rule, the two
looks no longer switch at the midpoint. A fill or outline only one side has
fades out (or in), so a filled shape turning into a line loses its fill
gradually. When both fill, the even-odd side lies opaque underneath and the
other fades over it, so a donut's hole fills smoothly while it shrinks.

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.

On a slide change the show kept a clone of the old slide's texture handle
as the transition's "old" picture, then rendered the new slide into that
same texture with set(). Old and new were the same image, so every
transition (except Morph, which renders into its own texture) blended the
new slide with itself and looked like an instant cut. The old texture is
now taken out of show.tex, so the new slide gets a texture of its own.
