Plan step 36 (actions). <x-toast> renders data-md-toast with data-md-position, its snackbar data-md-toast-snackbar with a bound data-md-two-line, data-md-toast-content with a bound data-md-toast-wrap, and data-md-toast-action/-dismiss; no class list. toast.css draws SnackbarTokens' inverse surface, 48/68px container, the two 40px controls reaching 48px targets with their own state layer and touch target (ACT-18), the enter transition and the position-start margin that grows from medium. data-toast becomes data-md-toast-snackbar and data-toast-action becomes data-md-toast-action (snackbar.js, navigation.js's hide-on-scroll guard, NavigationBarTest, CommunicationTest); a new data-md-toast-dismiss hook names the close button. ToastTest is rewritten on the hooks and ComponentStylesheet. CommunicationTest gains the owed tests: an actioned snackbar past the default timeout, Escape on a focused one, the live region before any message, and the two-line height with Alt+G reaching the action from elsewhere on the page.

{{-- The snackbar host: shows every toast, one at a time. Put it once in each layout, near the end
|
||
of <body>:
|
||
|
||
<x-toast />
|
||
|
||
It shows every `toast` browser event — what `NoNameWeb\LivewireMaterial\Concerns\Toasts`
|
||
dispatches from a Livewire component — and for `window.materialToast(title, options)` from
|
||
JavaScript (`{ type, description, timeout, sticky, action: { label, handler, event } }`).
|
||
Toasts queue and show in turn, each for its `timeout` (4s by default; M3 asks for 4–10s),
|
||
paused while the pointer or focus is on it. A toast with an `action` has no timeout at all,
|
||
as M3 requires — it waits to be read and acted on — unless the caller writes a `timeout` out.
|
||
A toast with an action or no timeout gets a close button. Pressing the action closes the
|
||
snackbar, calls `handler` and dispatches `event` (a name) on `window`; both may be given.
|
||
|
||
`sticky: true` keeps a toast until it is dismissed or its action pressed, without holding up
|
||
the queue: a toast that arrives meanwhile shows in its place, and the sticky one comes back
|
||
once the queue is empty. One is kept at a time; a newer sticky toast replaces it.
|
||
|
||
The live region is the host itself, not the snackbar: a region must be in the page before its
|
||
contents change for a screen reader to announce them reliably, and the snackbar comes and
|
||
goes (ACT-02). It is `aria-live="polite" aria-atomic="true"`, as M3 asks for a snackbar
|
||
(never assertive); a `type` picks the region's role — `alert` for an error or a warning,
|
||
`status` otherwise — and the explicit `aria-live` keeps even those polite.
|
||
|
||
Hooks for tests and styling: `data-md-toast` on the host, `data-md-toast-snackbar` on the
|
||
snackbar on screen, `data-md-toast-action` on its action button and `data-md-toast-dismiss`
|
||
on its close button. Drawn by resources/css/components/toast.css.
|
||
|
||
`@persist` keeps the host across wire:navigate, so a toast dispatched with `redirectTo` is
|
||
still on screen when the next page arrives.
|
||
|
||
There is no state icon: M3 says to avoid one in a snackbar ("use a dialog instead if an icon
|
||
feels necessary", ACT-20), and both lines of the message are plain inverse-on-surface — M3
|
||
gives the supporting text no fourth colour and tells the two lines apart by position. The
|
||
40px action and close buttons reach M3's 48px target without growing the container (ACT-18).
|
||
Escape dismisses a snackbar that holds the focus (ACT-34).
|
||
|
||
Alt+G moves the focus to a snackbar that carries an action, from wherever the page had it —
|
||
M3 asks for a documented shortcut on the web, since a snackbar never takes the focus itself
|
||
and a keyboard has no other way to reach one (ACT-34). It does nothing when the snackbar on
|
||
screen has no action.
|
||
|
||
M3's snackbar (SnackbarTokens, androidx Compose Material 3, Apache-2.0): inverse surface,
|
||
body-medium text, a label-large action in inverse-primary, extra-small corners, elevation 3,
|
||
48px for one line and 68px for two (SnackbarTokens.TwoLinesContainerHeight; the site's prose
|
||
says 64dp, and the token is the more precise of the two). A description is that second line,
|
||
so the container is pinned to 68px whenever one is there rather than left to grow into it. On
|
||
a compact window a two-line snackbar with an action wraps the action below the text, which is
|
||
the third of M3's five snackbar configurations ("two lines with longer action"). `position`:
|
||
`bottom` (centred, the default) or `bottom-start`. It lifts above a bottom bar through
|
||
`--material-bottom-bar`, and publishes its own height as `--material-snackbar-height` so a
|
||
FAB can lift clear of it — M3: a snackbar appears above a FAB, never in front of or behind
|
||
one (ACT-17). A compact window (below `medium`, 600px) gets the full-width snackbar; from
|
||
`medium` it hugs its line length instead, as M3 asks. --}}
