A text box with a glow in its shape properties but no fill and no line got a
blurred ring round the whole box; PowerPoint shows only the text's own glow.
The glow of a frame with a line, and of a filled shape, is unchanged.

shape_at folds a 3-D camera's turn into the shape's transform, so
per_point() measured its foreshortening as if it were a group's
child-coordinate scale: in a 1:1 group, a shape under a turned camera
got a factor other than 1 and drew its extrusion depth, contour and
bevel at the wrong size. The factor is now measured on the transform
before the turn (m with the camera's affine taken back out), and the
turned transform still draws the geometry.

A group's child coordinates scale its shapes' boxes, but extrusion
depths, contour widths and bevel sizes are points, as PowerPoint draws
them. The renderer applied them in the child space, so the group's scale
multiplied them: a 1 pt contour on a small extruded cube in a legacy
group (1360 child units across a 61 pt group) was drawn hundreds of
points wide, a band across the whole slide, and the cube's extrusion ran
off towards the vanishing point.
per_point() gives the shape-space units per point (the inverse of the
child-coordinate scale that line_space already separates for line
widths); the extrusion depth, contour width and bevel width and height
are converted with it before drawing. Outside a group it is 1.

The renderer lays every slide background over white (as PowerPoint does),
so a PNG export was always opaque. A new transparentBackground option leaves
the slide background out (both the white underlay and the background fill),
so only what is on the slide is drawn over transparency. Shapes filled with
the background (useBgFill) still show it.
- render: RenderOpts::transparent_background
- engine: file.export {transparentBackground} (PNG only; other formats
refuse it and write nothing), file.render {transparentBackground}
- UI: Transparent background checkbox in the Export dialog (PNG) and in
File > Export > Change File Type > PNG; the web download honours it
- CLI: render --transparent
Fix-ups in the merge (review): uniform-width and highlighter strokes are drawn as one path (on
the slide and in the live preview) so see-through ink doesn't darken where segments overlap;
segment pairs are destructured instead of indexed; tests that build pointer events set the new
pressure field.

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.

Copy puts HTML on the pasteboard with the same plain words, so Pages keeps
bold, italic and underline, and a paste of that HTML keeps them here. A
shape with no text copies out as a picture.

A default export is 2 pixels per point. Without a resolution, Preview
treats those pixels as 72 dpi and the picture opens at twice the slide's
size. PNG pHYs and JPEG JFIF density now say scale times 72, so the
default is 144 dpi. Screenshots stay untagged.

The preedit was already stored in the cell. It is now laid out the same
way the cell is drawn, and the editor underlines it in place, thicker
under the part being converted. The caret and the input method's
candidate window sit in that cell. Notes stay an egui text field.

A pen reading of 1 is the full pen width. A lighter touch draws a thinner
stroke, and a zero reading stays visible at 8% of the pen. A mouse, a
missing or non-finite reading, and a stroke whose samples are all the old
placeholder 0.5 still draw at the pen width. PPTX keeps one width per
stroke: the mean of the samples for a pressured stroke, the pen width for
a legacy one. Tilt is not read.

Radar and filled radar charts are drawn polar: spokes per category,
polygon gridlines and value labels up the first spoke. Stock charts
draw high-low lines with close dashes, or up/down bars between open
and close, and are saved as c:stockChart (hiLowLines, upDownBars)
instead of a line chart; c:upDownBars is read, and chart.options takes
upDownBars. New stock charts start as high-low-close and new combo
charts as columns with a line.

sp3d extrusionH (with extrusionClr, srgb or scheme) under a camera that
turns the shape now draws the shape's sides: its outline swept from the
back face to the front along the camera's view of the depth axis, in the
side colour shaded, before the face. camera::project3 projects points
off the shape's plane.
Notes pages and handouts lay out the master's header, date, footer and
page-number placeholders with deckcraft-text (render::place_master_texts),
so their text wraps in the placeholder and keeps mixed run formatting,
drawn as visible glyphs. Stacked on #580.
These Office 2016 charts were drawn as plain columns. Now:
- waterfall: bars float from the running total, total points
(cx:subtotals, now read into Chart.subtotals) stand on the axis and
reset it, increases/decreases/totals take accents 1-3 with a matching
legend, and connectors join each bar to the next;
- funnel: centred bars as wide as their value, category labels on the
left and values inside;
- treemap: squarified tiles in proportion to their value, labelled;
- sunburst: the innermost level as a ring with an open centre.

ui_soak_tests.rs drives the app through the egui test harness with seeded
random clicks, drags, keys (plain, Ctrl, Shift), typing and scrolling over the
sample deck. Every ten actions it checks that every document validates, the
selection is in range, undo, journal, thumbnail and texture caches stay
bounded, and no command or render panic was caught; at the end, that input
really reached the editor and the mean frame stays under 250 ms. Two seeds x
150 actions run in CI; DECKCRAFT_UI_SOAK_STEPS/SEED run it long.
Panics swallowed by the guards were invisible to tests: Session now counts
them (panics_caught) and deckcraft_render::panics_caught() counts render
panics drawn as blank. Textures::thumb_count exposes the thumbnail cache size.

A read-only command, {slide?, x, y (slide units), scale?}: the slide is rendered and
the pixel at the point is returned as {color: "RRGGBB", alpha, x, y}. This is what the
Eyedropper takes, and what scripts and MCP use to read a colour off a slide. A point
outside the slide, a missing or non-numeric coordinate or an unknown slide is an error.
A shape seen through a 3-D camera preset (isometric, perspective...) or
turned with a:camera/a:rot drew flat and front-on. PowerPoint turns the
shape's plane in space and projects it. Fitted black-box to its exports
(a picture with coloured corner markers under every preset and several
rotations; every fit within half a point on a 100 x 75 pt shape): points
about the centre are turned Rz(-rev) Rx(lat) Ry(lon), perspective cameras
then dividing by D / (D - z) with D about 5-16 shape sizes; a:rot turns
the other way about the horizontal and vertical axes. DeckCraft now draws
the shape under the affine transform that best fits its turned corners:
exact for orthographic cameras, within 2% of the size for perspective
ones (an affine map can't foreshorten). Oblique cameras leave a flat
shape as it is; depth (extrusion) is not drawn.
Wild synthetic set: camera presets 15.02 -> 6.35, 3-D picture styles
16.00 -> 7.72, extruded cameras 21.41 -> 19.74.

A reflection on a picture (PowerPoint's "reflected" picture styles) drew
nothing: the reflection painted the shape's fill, and a picture has none.
It now mirrors the picture itself, clipped to its outline, under the same
fade.
Wild synthetic set: picture effects slide 16.77 -> 16.00 (the rest is
3-D camera rotation, not modelled).

An outline naming no join was always rounded. PowerPoint rounds most
presets but mitres some by default: classified per preset by comparing
its export (8 pt outline, no join) with round- and miter-joined renders:
the plus, right/up/down block arrows (not the left one), chevrons, stars
from five points up, the equation shapes, curved ribbons and the action
buttons. Miter joins also take PowerPoint's default limit of 8 widths
(kurbo's default was 4), so sharp star points no longer bevel off.
Wild synthetic set: joins slide 0.43 -> 0.21, outline-on-pattern slide
3.95 -> 3.76, preset galleries slightly better.

The shadow of a picture is the picture recoloured to the shadow colour,
but drawing the picture left its pixel-space transform set, so the
recolouring rectangle (sized in points) covered only part of a picture
whose bitmap is bigger than it is shown: a 400 px photo at 240 pt cast a
shadow of its top-left corner only. The shape's transform is restored
before recolouring.
Wild synthetic set: framed pictures with shadows 7.67 -> 5.95, rotated
picture with a shadow 10.67 -> 10.07.

Explicit cell borders were stroked as plain solid lines (no dash, compound
or cap), and diagonal borders (lnTlToBr, lnBlToTr) were read but never
drawn. Both now go through the shape line stroker; diagonals are drawn
under the cell edges.
Wild synthetic set: border styles slide 5.67 -> 2.26, thick merged-cell
borders 1.20 -> 0.69.
