Draw the snackbar host without Tailwind
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.

/*
|
||||
* <x-toast>: the snackbar host — shows every toast queued behind it, one at a time.
|
||||
*
|
||||
* SnackbarTokens (androidx Compose Material 3, Apache-2.0): inverse-surface container,
|
||||
* inverse-on-surface text, an inverse-primary action, extra-small corners, elevation 3, 48px for
|
||||
* one line and 68px for two (SnackbarTokens.TwoLinesContainerHeight — the more precise of M3's
|
||||
* two published figures; the site's prose says 64dp). `[data-md-two-line]`, bound from whether
|
||||
* the current toast carries a description, pins the container to 68px instead of leaving it to
|
||||
* grow into it; below `medium` (600px), a two-line snackbar with an action wraps the action under
|
||||
* the text through `[data-md-toast-wrap]`, bound the same way — M3's "two lines with longer
|
||||
* action" configuration.
|
||||
*
|
||||
* It lifts above a bottom bar through `--material-bottom-bar`; `data-md-position="bottom-start"`
|
||||
* moves it to the start edge, with M3's margin growing from `medium`. resources/js/snackbar.js
|
||||
* publishes the snackbar's own height as `--material-snackbar-height`, so a FAB (fab.css) can
|
||||
* lift clear of it — M3 puts a snackbar above a FAB, never in front of or behind one (ACT-17).
|
||||
* Below `medium` it is full width; from there it hugs its line length, which an application's own
|
||||
* class can still bound.
|
||||
*
|
||||
* The action and the close button are both drawn at 40px but reach M3's 48px target (ACT-18) with
|
||||
* the same `::after` touch target the shared classes use (foundation/interaction.css); they draw
|
||||
* their own state layer and focus ring instead of those classes because the action's ink is
|
||||
* inverse-primary, not the button's inherited inverse-on-surface.
|
||||
*
|
||||
* It enters on a translate and a fade on the fast spatial spring, `@starting-style` giving both a
|
||||
* start. No state icon: M3 says to avoid one in a snackbar (ACT-20). The live region is the host
|
||||
* itself, in the page before any message is, never the snackbar that comes and goes (ACT-02);
|
||||
* resources/js/snackbar.js queues, times and dismisses a toast, including on Escape while it
|
||||
* holds the focus and on Alt+G, which moves the focus to one carrying an action (ACT-34).
