With nothing focusable inside, showModal() focuses the <dialog> itself.
Chrome's scroll containers are keyboard-focusable, so there the scrolling
body became the focus delegate and modal.css drew its inset ring; Firefox
and WebKit focused the dialog, where the arrow keys scroll nothing, and
WebKit never lets Tab reach a scroll container, so a keyboard could not
read a long text-only dialog there at all.
<x-modal> now opens through materialShowModal() (resources/js/dialog.js):
showModal(), and when the dialog took the focus itself and its body
overflows, the body gets tabindex="0" and the focus, as in Chrome. The
tabindex goes when the dialog closes. The body is wire:ignore.self, like
the dialog: a Livewire render would otherwise morph the tabindex away and
WebKit dropped the focus out of the dialog. ContainmentTest now also
checks the focus stays on the body through a render.

Plan step 36 (containment group): <x-modal>'s class lists move into
resources/css/components/modal.css, keyed on data-md-modal (with
data-md-fullscreen) and data-md-modal-box/-bar/-head/-title/-subtitle/
-body/-content/-actions. Sizes stay px (560/280/48px matching
DialogTokens.kt/FullScreenDialogTokens.kt and the 56px full-screen
header, C-17), spacing the measurement tokens, breakpoints a literal
600px range query.
The phone-only header bar and the pinned head/actions keep their
existing responsive behaviour (a subtitle or an icon keeps the head on
screen below 600px; only the bar's own divider-eligibility needs a
computed flag, since it alone can sit beside a head that is also on
screen) — reproduced with :has() against data-md-icon/
data-md-modal-subtitle wherever that is self-contained, and with an
explicit data-md-modal-divider attribute where it is not. The
scroll-driven dividers rename data-dialog-head/-actions ->
data-md-modal-head/-actions, data-overflow-top/-bottom ->
data-md-overflow-top/-bottom (resources/js/dialog.js); the
dialog-dividers Alpine directive keeps its name, since it isn't a
data-md-* hook.
resources/css/components/dialog.css (Tailwind-era) is replaced by
modal.css, imported from the Containment block of components.css;
its import leaves resources/css/tailwind.css. No other component
renders <x-modal> or dialog.css's rules (checked: datepicker,
timepicker and search draw their own dialog-shaped surfaces
independently).

Plan step 23 (containment), containment.md § Missing: "no divider pinned
between a scrolling body and the header/actions". Every dialog now draws a
1px outline-variant rule under the header once the body is scrolled away
from its top, and over the actions while more of it is below; a body that
fits shows neither. The rules are pseudo-elements in the rows' own padding
(dialog.css), so showing one moves nothing, and x-dialog-dividers
(dialog.js) marks the wire:ignore.self <dialog>, which a morph leaves
alone, watching scroll and a ResizeObserver on the body and a wrapper
around the slot. The M3 gaps are split around the rules (8/8 under the
header, 8/16 over the actions). A full-screen dialog's rule sits under its
phone bar, and its action bar's always-on border follows the scroll too.
`separator` now means "draw both rules always" instead of rendering two
<x-divider> elements. The fade uses the effects-fast token, zero under
reduced motion.
