Observed on PowerPoint's export of long joined words:
- a line broken at a soft hyphen (U+00AD) ends with a visible hyphen ("Softhyphenatedwordsina-");
DeckCraft broke there but drew nothing. The hyphen now takes its room on the line;
- PowerPoint does not break after a zero-width space (it splits the word where it overflows
instead), where UAX #14 allows a break;
- an em dash ends a line but never starts one ("Em—dash—joined—" / "words—that—are—long—"),
where UAX #14 allows a break before it too.

Follow-up to the kerning rule: on the real corpus (ms6: titles condensed by 1 pt from the
master's title style) PowerPoint kerns condensed text, and a closer probe agrees for -0.6, -1,
-1.5, -2 and -3 pt (only -1.2 and -2.5 pt came out unkerned, which no simple rule explains). Only
spacing out by 0.6 pt or more now switches kerning off for the box. ms6 slides 2/7: 4.97 -> 6.44
-> back to 4.97, 7.05 -> 8.10 -> 7.05.

Every underline was a solid line 0.06 em thick at 0.12 em below the baseline, whatever a:rPr/@u
asked for. Underlines now sit at the font's own underline position and thickness (post table),
where PowerPoint draws them (Arial 96 pt: 10 px below the baseline, 7 px thick), and each style
is drawn as measured on PowerPoint's export: dbl two lines 0.55 thick spanning one thickness above
to the single line's bottom; heavy from one thickness above to 0.55 below; dotted dots and gaps one
thickness long; dashes three long with gaps of two; wavy a thin zigzag every 3.9 thicknesses. The
"words" style underlines spaces too, as PowerPoint draws it. Dashes and waves are new Deco line
kinds the renderer fills or strokes (warped text draws their boxes).
Underline slides: w14-xml s10 11.49 -> 10.43, s11 6.64 -> 4.06; w06-charfmt s3 9.66 -> 9.51,
s4 7.63 -> 7.44.

Tab stops were all left stops: a:tab/@algn was read and saved but ignored. As PowerPoint draws
them, the text after a tab (up to the next tab or line break) now ends at a right stop, is
centred on a centre stop, and has its first "." on a decimal stop (text without one ends there);
when that text is wider than the room before the stop it starts where the tab is, never further
left. Measured on PowerPoint's export: "right" ends at 180 pt, "12.5" and "1234.567" put the
point on the stop, "12,5" and "nodot" end at it.
A tab whose stop lies past the end of the line now starts the next line, so the text after it
sits on that line's first stop, as PowerPoint wraps "abcdefghij<tab>k<tab>l<tab>m…".

A run's solid fill with a:alpha was resolved into the glyph colour's alpha and also kept as the
run's fill opacity, and the renderer multiplied both: text at 60 % transparency drew at 16 %
opacity instead of 40 %. The colour now carries the transparency alone. PowerPoint's export of
"Transparent 60% text" (red) is a light red that now matches.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
Small capitals were drawn at the full size of the run's first character: glyph runs grouped
cells by style and face only, so "HxHx" drew every letter at the capital's size on the small
capitals' narrower advances (letters overlapped). A lowercase letter in small caps now starts a
run of its own at 80 % (PowerPoint's small capital "X" is 0.81 of the capital "H" in Arial).
All caps and small caps mapped "ß" to "S" (the first character of "SS"); PowerPoint leaves a
character whose capital is a sequence as it is ("ß", "fi", "ʼn"), and maps the rest one to one.

PowerPoint kerns pairs (a:rPr/@kern) only while no run of the text body is spaced out by 0.6 pt
or more or condensed by 1 pt or more; then no run of that box is kerned, even runs without
spacing. Measured on Arial 40 pt "AVATAR": spacing 0, 0.01, 0.5, -0.6 and -0.99 pt keep the pairs
(146 px wide), 0.6, 0.8, 1, 1.5 and -1 pt drop them in every paragraph of the box (158 px plus the
spacing). DeckCraft kerned spaced titles, making "AVATAR"-like words 12 px too narrow at 40 pt.

PowerPoint does not resolve neutral characters with plain UAX #9: the language of each run
(a:rPr/@lang) decides. Measured with every space highlighted in its own colour:
- in a run of a left-to-right language (or none) punctuation and digits are left to right and a
space takes the direction of the character before it, so "abc HE1 HE2 def" shows the space after
the Hebrew words on their left, and an English sentence in an RTL paragraph keeps its full stop
at its end;
- in a Hebrew/Arabic run, neutrals between text of one direction take it, all others are right
to left, and digits are a number in the right-to-left text unless left-to-right text precedes.
Paragraphs with explicit embeddings keep the full algorithm. Bidi probe deck: mean diff 11.1 ->
10.0 on the four mixed-direction slides; corpus poi 6.660 -> 6.654, others unchanged.

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.

Value axes showed raw numbers ("800000") with a fixed ~5-interval scale and
fixed label gutters, deleted axes were still drawn, and data labels ignored
their number format, so Russian business charts read "516600000" where
PowerPoint shows "516 600 000 ₽".
- New deckcraft_model::numfmt: Excel number format codes (sections for
positive/negative/zero, quoted and escaped literals, _x padding, *x fill,
[$sym-lcid] currency, [colour]/conditions dropped, 0/#/? placeholders,
grouping with ',' or the locale's literal space, trailing-comma scaling,
%, General) with digit grouping and decimal mark from the chart's
language (c:lang: ru-RU -> "800 000", "12,5%").
- Reading: each value axis' numFmt, c:delete, scaling min/max and
majorUnit, for the primary and a combo chart's secondary axis; data
labels' numFmt (series, then group, else the source data's formatCode);
the chart's c:lang. The primary value axis is the one on the left
(bottom) and the secondary the one on the right/top or crossing at max,
whatever the plot groups' order.
- Scale (Chart::axis_scale): fixed bounds and unit where given, else the
data plus 5% headroom rounded out to the smallest 1-2-5 unit that leaves
as many intervals as the axis has room for labels, as PowerPoint does
(0-800 000 by 100 000, 0-7 000 by 1 000 on the sample deck).
- Rendering: labels in the axis format, gutters sized to the longest label,
deleted axes draw no labels and take no room, data labels in their own
format.
A combo chart (columns plus lines, often with the lines on a second value
axis) was read with each series' type but drawn as lines only, on one
scale, so a spend-and-clicks chart showed the clicks as a flat line along
the bottom and no columns.
- Reading: a plot group whose value axis isn't the first group's is on the
secondary axis (Series::secondary_axis, now set).
- Model: Chart::series_kind, on_secondary and axis_range (per axis; a combo
stacks only its stacked series).
- Rendering: bar-like series are drawn as bars (clustered or stacked among
themselves), the others as lines/areas over them, each against its own
axis; the secondary axis' labels go on the right. Line series use their
line's colour and width (where PowerPoint keeps them), also in the legend.
Long category labels wrap onto two lines.
* 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.

Outlines, dashes, arrowheads and ink strokes were drawn under the full
transform, including the mapping of the group's child coordinate space onto its
box. A group whose children use small legacy child coordinates (scale ~1600)
therefore stroked 0.75 pt lines about 1200 pt wide and covered the slide. Inside
a group the outline is now carried through that mapping and stroked under the
slide-level view, so the line width, dash lengths and arrowhead sizes stay in
points, also for groups scaled unevenly.
* ActiveX controls show their pictures
A slide's p:controls are read: each control with a p:pic (the image PowerPoint shows for it,
often a WMF) becomes a picture above the slide's shapes.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
* Metafiles draw their text, pattern and hatch brushes
deckcraft-metafile (still kurbo + thiserror only, so it builds for wasm):
- Text: WMF EXTTEXTOUT/TEXTOUT and EMF EXTTEXTOUTW/EXTTEXTOUTA/SMALLTEXTOUT with the
selected font (CREATEFONTINDIRECT, EXTCREATEFONTINDIRECTW: face, signed LOGFONT height,
width, weight, italic, underline, strike-out, escapement, charset), text and background
colour, background mode, TA_* alignment and TA_UPDATECP, the dx array (ETO_PDY pairs too),
ETO_OPAQUE fills and ETO_CLIPPED clips. 8-bit strings decode through their charset
(Windows-1252/1250/1251; symbol fonts keep their codes at U+F000; double-byte sets keep
their advances). The neutral Item::Text carries a text-space-to-picture transform, so the
mapping and escapement are folded in and glyphs are never mirrored.
- Brushes: WMF DIBCREATEPATTERNBRUSH, EMF CREATEDIBPATTERNBRUSHPT and CREATEMONOBRUSH, and
BS_HATCHED, as Item::Pattern tiles in 96-dpi pixels; WMF PATBLT. The XOR / AND-pattern /
XOR see-through shadow of old PowerPoint WMFs draws its pattern in the XOR colour.
- MFCOMMENT escapes with an embedded EMF are ignored: PowerPoint draws the WMF's records.
- Pattern pixels and text count against the byte budget; strings are capped.
deckcraft-render draws text through deckcraft-fonts with the face slide text would use
(document_face), symbol fonts mapped as bullets map them (deckcraft_text::symbol_char, now
public, with Webdings), per-character fallback, the file's advances, GDI cell metrics for
top/bottom alignment, underline/strike-out and synthetic bold/italic. Tiles below 1.5 output
pixels per cell are drawn as their average colour.
On the 24 corpus slides that show a metafile, mean abs diff against PowerPoint goes from
28.31 to 5.06 (with the OLE/ActiveX preview commits).

* 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).

* #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,

* 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.

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.

* Text warps: draw WordArt prstTxWarp presets, round-trip their adjusts
All 40 DrawingML text-warp presets now render instead of drawing flat text.
A warp is a list of bands over the shape's text rectangle (insets ignored):
fill bands stretch the ink of their lines between a top and a bottom guide
(positions by arc length, one horizontal scale for the whole text), follow
bands (arch, circle, button) set lines at natural size along an ellipse arc,
lines stacking outwards on parallel curves, with no wrapping. Lines are
shared over multi-band presets in order (ceil(n/k) per band).
The guide curves were fitted to PowerPoint renders of synthetic decks of
"I" bars (black-box observation, defaults and changed adjusts, 1-3 lines);
most presets match within about a point on a 420 x 200 pt box.
- geom: warp module (guides, presets, band mapping) with unit tests
- render: glyph outlines and underlines flattened, subdivided and mapped
- text: follow warps lay out without wrapping
- model/pptx: BodyProps.warp_adj read from and written to prstTxWarp/avLst

* Text warps: bands with fewer lines keep the fuller band's text height
Multi-band fill warps (Deflate-Inflate, Button Pour) map a box as tall as
the tallest band's ink onto every band, centred on the band's own ink, as
PowerPoint does: a band holding one line next to a band of two keeps the
line at the same size instead of stretching it over the whole band.

PowerPoint keeps fi, ffi and Calibri's ti apart and kerns a run only when
a:rPr/@kern is set and the size reaches it; DeckCraft shaped with the font's

* Render: shadows, inner shadows and glows spread like PowerPoint's
Measured on PowerPoint's export of probe shapes:
- outer and inner shadows are blurred by a third of the blur radius (was
half), so their profile matches pixel for pixel;
- an inner shadow falls inside along the edges its direction points to (45
degrees: bottom and right); DeckCraft put it on the opposite edges;
- a glow of radius r is half strength about r/2 out and gone by r (was a
wider, softer halo).

Bullets in Wingdings, Wingdings 2/3, Symbol and other symbol fonts were
always swapped for a look-alike from one Wingdings table, so a Wingdings 2
star (0xEA) became a round dot. When the deck's symbol font is installed,
its glyph is drawn (symbol fonts map character codes at U+F000 + code), as
PowerPoint does; otherwise Wingdings 2 and 3 codes get their own
look-alikes.

* Tables: styles the file defines are read, drawn and kept
PowerPoint writes the definition of every table style a deck uses into
ppt/tableStyles.xml. DeckCraft mapped a handful of GUIDs to its own looks
and drew any other style as Medium Style 2, so themed and light styles came
out in the wrong colours, and dropped the definitions on save.
The reader now keeps each definition (whole table, bands, first/last
rows and columns, corner cells, table background; fills, theme fill and
line references, borders, text colour and bold) on the presentation, and
tables using one keep its GUID. The renderer applies the parts that cover
each cell in the spec's order, a part's edge lines on its region's edges
and its inside lines within it, and paints fills as real fills (gradients
and see-through colours). The writer puts the definitions back as read.

The soft-edge mask was the bounding box shrunk and blurred, so ovals and
other non-rectangular shapes kept hard edges where the box was wider, and
a rectangle's fade began outside it. The mask is now the outline itself,
shrunk by 0.85 r (a stroke punched out of the fill) and blurred by r/3:
transparent at the outline, half opaque 0.85 r inside, as measured on
PowerPoint's export of a 12 pt soft edge.

Path gradients that follow a rectangle (path="rect") or the shape's own
outline (path="shape") were drawn as circles. They're now rasterised into
a small image of the bounds: rect takes the larger of the horizontal and
vertical shares of the distance from the focus to the edge (X-shaped
contours), shape the share of the way from the focus to the outline along
the same ray (an ellipse gives ellipses, a triangle triangles), as
measured on PowerPoint's export. The two path probe decks now match it to
a mean pixel difference of 1.7 and 0.6 (from 15.6 and 22).

Pattern fills were approximated (dots, bars or a grid per family, on an
8-point cell), so pct30 looked like sparse dots and wave like a dot grid.
Every one of the 54 DrawingML presets now draws its 8x8 tile, each cell one
96-dpi pixel (0.75 pt), laid out from the slide's origin. The tiles were
read from PowerPoint's own export of each preset at two output pixels per
cell; the pattern probe deck now matches it to a mean pixel difference of
0.2 (from 62).

Circled-number lists (circleNumDbPlain) and character bullets whose glyph
isn't in the paragraph's font were drawn as missing-glyph boxes (numbers)
or always from Inter (characters). Both now go through the usual font
fallback, as PowerPoint draws them.

Run shadows and glows (a:rPr/a:effectLst outerShdw, glow) were read but
never drawn. The text layout now carries them on each glyph run (colours
resolved, sizes scaled with autofit) and the renderer draws every run's
shadow, then every glow, blurred, under the text. A text glow is solid to
about a third of its radius past the letters and fades out by two thirds,
as measured on PowerPoint's export. needs_filters also looks at text
effects (runs, list styles, master text styles), so they render with the
blur filter.

A gradient on text was read but drawn in its first colour. Each line is now
filled with the whole gradient, spanning that line's text from its top to
its bottom and its first to its last character, as PowerPoint does. The
gradient builder moves out of fill_path into paint::gradient so fills and
text share it (and PowerPoint's two-colour ramp). Gradient colours are
resolved when the text style is made.
