Plan step 36. <x-fab> renders data-md-fab with data-md-size,
data-md-color, data-md-variant, data-md-extended and, collapsing on
scroll, data-md-collapse-on-scroll with a bound data-md-collapsed; it
passes its glyph's size to <x-icon>. fab.css draws FabBaseline/Medium/
LargeTokens and ExtendedFab*Tokens per size, the container and filled
colours, elevation 3 and 4 on hover, the state layer and focus ring,
and the collapse morph that leaves actions.css.
data-fab becomes data-md-fab, also in navigation.css (the rail flattens
a nested FAB) and toolbar.css (a docked toolbar's FAB), with their tests.
The actions browser test gains the owed collapse-on-scroll test.

Plan step 22, actions.md § Missing (FAB to extended FAB scroll collapse):
M3 has an extended FAB collapse to a FAB on scroll-down and re-extend on
scroll-up, and `<x-button fab>` only swapped on window width.
`<x-fab collapse-on-scroll>` (extended, with an icon) takes a
`materialFab` flag from the new resources/js/fab.js, which reads the
window's scroll once a frame, ignores moves under 8px and extends again
near the top. The morph is CSS in actions.css: the label sits in a grid
track that closes to zero, the gap and minimum width follow on the
default spatial spring, and the label fades on the effects one; reduced
motion swaps outright through the motion tokens. The label is clipped, not
removed, so the collapsed FAB keeps its accessible name.

Its trigger holds two aria-hidden icons and wrote aria-label only when a caller
passed `label`, so an unnamed button was the default; `label` now falls back to
"Toggle menu" and is always written. The list had no ceiling, so six items ran
off a landscape phone — it now scrolls under the FAB, which stays put — and its
items rose into place but vanished on close, because the popover took its
display away before they could move. Plan step 18, actions.md ACT-21, ACT-32,
ACT-33.

M3 is explicit twice over — never disable a FAB, remove it instead — and the
prop painted the full disabled treatment with nothing warning against it. It is
gone; hiding the FAB is the documented answer. The extended FAB's icon-to-label
gap goes to M3's 16dp at md and 20dp at lg, the small one takes the baseline's
80dp minimum width, and the root gains a `data-fab` hook for a place that draws
a nested FAB its own way. Plan step 18, actions.md ACT-08, ACT-16, ACT-31.

M3 asks a FAB's icon and a default (non-toggle) icon button's icon to be filled,
never outlined; the toggle half of that rule was already right, so only the
`$selected === null` case changed. Every glyph these components draw at 20px now
passes `optical="20"` for the cut M3 draws at that size — button xs/sm, group,
menu item, the alert, snackbar and FAB-menu close buttons, the stat's icon.

<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.
