Plan step 36. <x-button-group> renders data-md-button-group (standard or
connected), data-md-size, data-md-shape and, with a selection,
data-md-selection and data-md-selection-required. button-group.css now
also draws the standard group: its gaps per size, the square corner scale
it hands its buttons, and the press expansion that widens a pressed label
button while its neighbours give way. groups.css keeps only the split
button until that is rewritten too.

Plan step 36. <x-button> renders data-md-button with its variant, colour,
size, shape, icon-button width, selected state and compact FAB as
data-md-* attributes, and passes the glyph's size to <x-icon>.
button.css draws Button*Tokens' geometry per size, the colour roles
through custom properties that the disabled treatment replaces, the
state layer, focus ring and 48px target, and the compact FAB below
600px. Its corner rules carry no specificity (:where), so a group's
stylesheet reshapes the buttons inside it with any selector; the
split button no longer passes an empty corners prop, which is gone.
data-icon-button becomes data-md-icon-button, also in groups.css,
toolbar.css and theme-toggle's own button (navigation group), and the
AppBarTest assertions follow the new hooks.

Plan step 22, actions.md § Missing (Square-by-default button groups): M3
lists "Default shape | Round, square" as a button-group configuration and
neither `<x-button-group>` nor `<x-group>` had a `shape` prop, so a group
of square buttons still drew round outer corners.
`shape="square"` passes the square corner scale to every child through
`data-shape` and two new variables in groups.css: `--group-outer` is what
the two ends of a group round to (half the height when round, the corner
its inner edges take when square — M3's square table, 4/8/8/16/20dp), and
`--group-square`/`--group-square-pressed` give a standard group's buttons
the scale `<x-button shape="square">` draws. The selected rules keep
`--group-full`, so a selected button in a square group rounds: M3 has a
toggle inside a group swap shape on selection either way.

ButtonXSmallTokens puts 16dp either side of an xs label, where the button, the
<x-group> segment and --group-pad all wrote 12px; the variants table calls 16dp
the Expressive value twice over. A standard button group also dropped onto a
second line on a narrow window, which M3 forbids — and the press expansion only
ever reaches a neighbour on the same line. Plan step 18, actions.md ACT-09,
ACT-10.

It borrowed the connected group's corner variables, so its inner corners were
wrong at four of five sizes and shrank under the finger where SplitButton*Tokens
grows them; its chevron took the icon-button table's size at every step, sat dead
centre, and turned over on the expressive spring. groups.css now carries
--split-inner, --split-icon and --split-nudge per size, and the rotation uses
M3's standard scheme. Plan step 18, actions.md ACT-06, ACT-07, ACT-29, ACT-30.

An <x-group> segment is a plain label, 32px or 40px tall, with nothing reaching
past it, and nothing gave a connected <x-button-group> its 48dp minimum width
either — both numbers M3 names and tells you not to reduce. The segment now
carries the shared `touch-target` utility and a 48px floor, and groups.css puts
the floor on the buttons a caller nests in a connected group. <x-button> drops
its hand-rolled ::after for the same utility. Plan step 11, actions.md ACT-05.

Connected segments and split halves wrote their full corners as
--md-sys-shape-corner-full, 9999px, beside 8px inner corners on the same
element. A box whose radii add up to more than its side has every radius
scaled by one factor, so the inner corners shrank to a hundredth of a pixel
and drew square. Full is now half the size's height (--group-full), which no
side can overflow. A browser test fails on any radius in a group or split
button larger than half its height.

<x-button> (label buttons, icon buttons and toggles in five sizes, with
filled, tonal, outlined, elevated and text variants in any colour role),
<x-tooltip>, <x-menu> with items, groups and separators, <x-button-group>,
<x-group> as a connected button group, <x-split-button>, <x-fab>,
<x-fab-menu> and <x-loading>. Sizes, colours and shapes come from
androidx Compose Material 3's tokens; the loading indicator ports its
Morph into SVG + SMIL.
Menus follow WAI-ARIA's menu button pattern on popovers placed by CSS
anchor positioning. Browser tests run in Chromium, Firefox and WebKit.
The showcase fetches the icon names on demand: inlined, they tripped
