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.

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.

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.

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).

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).

* 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).

`sniff` searched only the leading 4096 bytes for the content-types part, but
OOXML writers may place that part anywhere in the archive. Recent PowerPoint
builds (16.x) store it as the last zip entry, so every deck saved by them was
rejected with "not a presentation DeckCraft can read" although it imports fine.
In one real folder 169 of 300 decks were affected.
Look the part up in the zip's central directory instead. The regression test
re-packs the sample deck with the part last behind 64 KB of padding and
checks that it is both recognised and imported.
