Claude 887ea1e706 Slide show: click-triggered animations, per-slide state and hit testing
Make the slide show behave like PowerPoint for interactive decks.

- Hit testing resolves the topmost visible shape under the pointer.
  Non-interactive shapes block shapes beneath them; the hand cursor
  shows only over interactive shapes.
- Click-triggered animations (interactive sequences) play on shape
  click, repeat after their last step, and apply in click order so
  cycling "score ring" shapes work.
- Each slide keeps its own progress: returning to a slide through a
  link or Back restores hidden shapes and animation state.
- A shape with a link and an animation follows the link immediately;
  its animation clock only runs while the slide is shown and resumes
  with the remaining time on return.
- With advance-on-click off, background clicks still play animation
  steps but never change slide.
- A click on a playing step completes it at once.

Docs (gaps, animation and slide show parity, roadmap) are updated.

ZetenypappandClaude Opus 5.5 1baf1f5569 Copy and Cut buttons and menus put the text on the system clipboard (#431)
Ctrl+C and Ctrl+X ran edit.copy / edit.cut and handed the returned text
to egui's clipboard; the ribbon's Copy and Cut, the slide's right-click
menu, the menus, the palette and the control channel ran the same
commands through SlideApp::run, which dropped the text, so it never left
DeckCraft. SlideApp::run now keeps the text of a successful Copy or Cut
and hands it to the clipboard on the next frame, like pending URLs.

Regression test: copy_and_cut_commands_reach_the_system_clipboard runs
both commands and checks the frame's CopyText output (it fails without
the fix).

NetterSilver 7887a13868 Colour menus: an Eyedropper that takes a colour from the slide (#367)
Every colour menu ends with Eyedropper. Choosing it closes the menu; the pointer is a
crosshair over the slide with the colour under it and its hex beside it, a click takes
the colour (slide.colorAt) and Esc, a right click or a click off the slide cancels.
The colour comes back through the menu that asked, which opens for a frame and returns
it as if its swatch had been clicked, so Shape Fill, Shape Outline, Font Color, the
Format pane and the other callers all apply it their own way without changes.

Brandon ThomasandClaude Opus 5.5 0c5ddb5dea Gradients: read, write and draw a:tileRect
Gradient tile rectangles were dropped on import. PowerPoint's "from
corner" radial presets depend on them: fillToRect puts the focus on a
corner and tileRect stretches the gradient's box a whole size past it, so
the circle is centred on that corner and reaches the far one. Without it
(after the two-point radial change) such fills washed out. A linear
gradient now spans its tile rectangle; a radial one ends on the circle
around it, with the focus still placed in the shape's own box (fitted to
PowerPoint's export of the corpus deck tdf114848: mean diff over the
filled box 0.77). Round-trips through pptx.

Wild synthetic set: tile-rect gradients 16.74 -> 2.48.

Brandon ThomasandClaude Opus 5.5 d5e30557eb Transitions like PowerPoint: measured frame by frame and retuned (#366)
Every transition and Effect Option was built in PowerPoint (COM), exported as
video and compared frame by frame with DeckCraft at the same progress
(mean abs diff over 150 variants 35.7 -> 15.0, 0-255).

- anim: transition_frame(kind, option, t, aspect) with measured curves
  (smoothstep fades, ease-in-out moves, Cover/Uncover/Pan curves), directions
  and option meanings, soft edges as per-corner opacity, 3-D effects as
  perspective-projected cards, Dynamic Content moving slide contents over
  cross-fading backgrounds (Source::OldBack/NewBack/OldContent/NewContent);
  layer_mesh subdivides perspective quads so textures stay straight.
- New options: Page Curl Single, Glitter Hexagons, Shred In/Out, Zoom and
  Rotate; PowerPoint-style Effect Options labels.
- render: composite_transition (CPU twin of the show), render_slide_part,
  render_transition; deckcraft-cli render-transition FILE --slide N --t T.
- show: per-vertex opacity meshes, slide parts rendered once per transition.
- pptx: PowerPoint's elements and defaults (p:strips diagonal wipes, p14:warp
  and p:newsflash for Zoom, p:zoom for Shape In/Out, glitter pattern, shred
  rectangle/dir, prstTrans invX per preset, pageCurlSingle, defaults for
  randomBar/doors/window/pan/zoom); PowerPoint reopens DeckCraft's files with
  the same effects.
- Tests: measured curves, probes of which slide shows where at t, option
  coverage, per-frame triangle budget, PowerPoint XML and defaults round trip.

Brandon ThomasandClaude Opus 5.5 1660982e58 File tab: PowerPoint's File view (Home, New, Open, Info, Save As, Print, Export, Close) (#76) (#344)
* 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.

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

* 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: 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).

Brandon ThomasandClaude Opus 5.5 9d571ef644 Selection Pane: reorder by drag and drop, groups, Show/Hide All and Lock, as in PowerPoint (#133) (#332)
* #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.

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.

Brandon ThomasandClaude Opus 5.5 ea3b1159d5 Korean, Japanese and Chinese: input-method composition and interface text (#101) (#331)
* 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.

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

* 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.

Brandon ThomasandClaude Opus 5.5 f94f3c12d1 Canvas: objects off the slide show and can be grabbed around it, as in PowerPoint (#270) (#329)
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.

lloydandClaude Opus 5.5 9c64754f20 Read Markdown outlines as Markdown (#211)
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).

Claudio d5c62b640a Ctrl+C then Ctrl+V pastes objects that carry no text (Fixes #182)
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.

lloydandClaude Opus 5.5 e999424c79 Issue #106: zooming keeps the point under the pointer
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.

Fixes #106

7f1e152870 Links: Insert Hyperlink with a bare caret inserts the address; the show follows links (#31) (#45)
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.

alexanderalber e8c4c60884 Home: the title bar's Home button opens the start screen (#17) (#49)
It ran file.new, so each click silently added another blank presentation
and looked like it did nothing. Home is now a UI command (app.home) that
shows the start screen over the open presentations, with a "Back to …"
button; Escape or Home again goes back. Creating or opening a presentation
from it leaves it. While it's open, keys don't reach the hidden
presentation (only app shortcuts and Escape). ui.inspect reports `home`.

alexanderalber a8c983ba6b Colour menus: clicking the hex field no longer closes the menu (#32) (#47)
egui::Popup::menu closes on any click inside the popup, so the "More
Colors… #" field of every colour drop-down closed the menu before a value
could be typed. The colour drop-downs now open through
widgets::color_popup (CloseOnClickOutside): picking a colour still closes
them (color_grid calls ui.close()), and the other buttons in them
(Gradient…, the Weight, Dashes and Arrows submenus of Shape Outline) close
them explicitly.

alexanderalberandBrandon Thomas 788831834b Morph: a changed geometry morphs its outline (a circle turns into a star) (#27)
* 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.

ddbd71e297 Shapes: flipped shapes keep their text readable (#35)
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.

alexanderalber c543ef350e Slide show: transitions show the old slide instead of the new one twice (#33) (#46)
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.

4b09f35c1d feat(text, fonts): UAX #9 BiDi and Arabic complex script typography engine (#4)
* Sprint 1: bidi and Arabic typography engine

fonts: ISO 15924 script and a:latin/a:ea/a:cs slot classification;
shape_range shapes an item with the whole paragraph as HarfRust
pre/post context, explicit script/language/direction, glyphs kept in
visual order; per-grapheme-cluster fallback (slot face, theme script
font, OS cascade families, bundled craft-fonts face); GDEF ligature
carets.

text: UAX #9 levels for the whole paragraph (a:pPr/@rtl), itemization
by level, script, face and shaping style (paint-only changes no longer
split words), logical line breaking at cluster boundaries, per-line
L1/L2 reordering (L4 mirroring by the shaper); RTL start edge and
bullets, justLow kashida; caret Affinity, logical/visual movement,
bidi hit testing and selection as the union of visual boxes.

model/pptx: theme a:font script fonts and algn="justLow" round-trip.
engine: format.rtl (Right-to-Left Text Direction), justifyLow align.

* 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).

57545a99c8 Tables: rows grow to fit their text, cell text in the PDF text layer (#13) (#14)
* 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.

alexanderalberandBrandon Thomas fa9a94a1c0 Morph: shapes move, resize and blend; Words and Characters options morph text (#5)
* Morph: shapes move, resize and blend in the slide show

Morph used to fall back to a plain crossfade in the show: morph_pairs and
morph_xfrm existed, but nothing rendered frames with them.

- anim: morph_frame builds a frame from two slides. Paired shapes move along
  morph_xfrm (eased); a pure fill colour change blends, other content changes
  cross-fade on the same moving box. Unpaired shapes fade out/in, shapes with
  entrance animations or hidden media stay out of the frame.
- render: render_blend draws such a frame in one pass: both backdrops
  (background, master and layout graphics) cross-fade, every shape resolves
  against the slide it comes from, so placeholders keep their own layout.
  Renderer::slide is split into canvas/fields/backdrop to share the code.
- ui-egui: the show renders morph frames with these, crossfade otherwise.

* Morph: Words and Characters options morph text token by token

The transition option (objects/words/characters) was stored and round-tripped
but ignored by the show. With Words or Characters, paired shapes whose text
differs now morph their text instead of cross-fading it:

- text: GlyphRun records per glyph the paragraph character it draws, so
  glyphs can be grouped into words or characters.
- anim: morph_frame reads the option and lists such pairs in MorphFrame::text.
- render: morph_text draws them. Shared words (or characters) travel from their
  place in the old text to their place in the new one and grow or shrink to the
  new size; a different look cross-fades on the way. The remaining tokens fade
  while following a scale and shift fitted to the shared ones, so a line moves
  and rearranges as one. Rotated text falls back to a cross-fade.
  draw_layout_with's glyph drawing moved into draw_glyph for reuse.
- ui-egui: the show passes the pairs to render_blend.
