Plan step 22, actions.md § Missing (Grouped menu layout by gap): M3
Expressive's "Grouped" layout separates clusters with a gap rather than a
divider, and `<x-menu-group>` only had the labelled form.
`<x-menu-group gap>` holds its items in a box 2px apart
(SegmentedMenuTokens.SegmentedGap) whose ends round like a list's, and
stands 8px off its neighbours — the same 8px the separator keeps around
its line. `label` is now optional, so a cluster can be a gap alone. The
header says when to reach for which: the divider first, and always in a
menu long enough to scroll, where M3 says gaps are unsupported.

Plan step 22, actions.md § Missing (Submenus): M3's Expressive vertical
menu specifies submenus and the Left/Right keys that open and close them,
and the library had neither.
`<x-menu-item submenu>` puts its slot in a second popover on the item's
end, flipping to the start where there is no room. `materialSubmenu`
reuses the menu button pattern one level in: the item is its own trigger,
so the anchor move and the button lookup are overridden away; Right,
Enter and Space open it, Left and Escape close it and return the focus,
and a fine pointer resting on the item opens it after a moment. `items()`
now stops at the popover it belongs to, so the arrows never walk between
a menu and an open submenu. The menu publishes its container as custom
properties so a vibrant menu's submenus are vibrant too.

Items were 44px tall with the baseline menu's 12px sides, the separator had half
its 8dp padding, a disabled item was skipped by the keyboard entirely, a chosen
item was told by colour and shape alone, and the list simply faded in place. Now:
48px rows with 16px either side, an 8px separator, disabled items focusable but
never activatable, a trailing check on a selected item, and an enter-exit that
scales the list out of the corner nearest its trigger — the scale on the spatial
spring, the fade on the effects one. Plan step 18, actions.md ACT-11, ACT-12,
ACT-13, ACT-26, ACT-27, ACT-28.

The popover was fit-content with overflow visible, so a long menu ran past the
edge of the top layer, where the page's own scrolling cannot reach it. It now
caps at 18rem — less on a short window — and scrolls, as M3's menu behaviour
asks, and the keyboard brings the item it moves to into view. Plan step 11,
actions.md ACT-04.

The phone picker of <x-section-nav> drew the current section as a checked
menuitemcheckbox in tertiary-container, which a screen reader announces as a
choice rather than where you are, and it dropped the sections' badges, so an
open support count showed on the tabs but not on a phone. <x-menu-item> gains
current (aria-current="page", the selected shape in secondary-container,
the navigation indicator's colour) and badge (a dot or a count at the end of
the row), and the picker uses both.

<x-group hint-class> adds classes to the hint, as the text fields'
hint-class does, and a validation message still replaces the hint.
<x-menu-item icon-class> adds classes to the leading icon, for an icon
whose colour means something of its own, such as a sport's glyph.
A colour class there has to win over the component's own colour, and
which of two colour utilities wins depends on the order Tailwind emits
them (text-error comes before text-on-surface-variant). So when either
prop is given, the component's own colour is written with a :where()
variant that carries no specificity, as the fields' hint colour sits
in the components layer. A disabled item's icon stays disabled. Without
the props the markup is unchanged. The skill now also lists the fields'
hint-class, which it had left out.

<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
Pest's test server into HTTP 431s under Firefox.
