Plan step 36 (navigation group, first stream): <x-app-bar>'s class
lists move into resources/css/components/app-bar.css, keyed on
data-md-app-bar (with data-md-variant/-sticky/-subtitled/-scrolled/
-collapsed) and its parts data-md-app-bar-row/-leading/-headline/
-title/-subtitle/-search/-trailing/-action/-overflow/-expanded. The
overflow menu (two icon buttons below 600px, four from it, N-09's
312px search cap and N-11's three-column centred row) already matched
the audit; only its hooks, units and layer needed to change. Every
length is px, spacing through the measurement tokens where one
matches (M3's own "4dp leading/trailing space" and "16dp" headline
inset had no exact token, so those stay literal). Imports button.css,
menu.css and menu-item.css for the overflow menu the view renders.
Hooks renamed: every unprefixed data-app-bar-* attribute and
data-scrolled/data-collapsed to data-md-*, updated in
tests/Feature/Components/{AppBarTest,PaneTest}.php and
tests/Browser/{BarsTest,NavigationTest}.php. app-bar.js needed no
change: it reads the bar through $root, not by hook name.
tests/Feature/Components/NavigationStylesheetsTest.php is the
navigation twin of ContainmentStylesheetsTest.php, on the same
tests/Support/ViewClasses.php rule; its dataset starts at 'app-bar'
and a 'tabs' entry (once that commit lands) will read both
tabs.blade.php and tab.blade.php, since they share one stylesheet.
Added the owed browser tests (docs/plans/material-3-browser-tests.md):
the overflow at 599/600px, keyboard in its menu, a menu closing once
its width no longer shows it, and a wire:click action from both the
icon button and the menu item form.

* `<x-app-bar>`: M3 Expressive's top app bars (AppBarTokens.kt, AppBarSmallTokens.kt,
|
|
* AppBarMediumFlexibleTokens.kt, AppBarLargeFlexibleTokens.kt, androidx Compose Material 3,
|
|
* Apache-2.0; docs/reference/m3/components-navigation-selection-inputs.md § Top App Bar).

*
|
|
* [data-md-app-bar] the bar; data-md-variant, data-md-sticky, data-md-subtitled,
|
|
* data-md-scrolled/data-md-collapsed (resources/js/app-bar.js)
|
|
* [data-md-app-bar-row] 64px, sticky at the top of the bar
|
|
* [data-md-app-bar-leading] the `navigation` slot
|
|
* [data-md-app-bar-headline] [data-md-app-bar-title], [data-md-app-bar-subtitle]
|
|
* [data-md-app-bar-search] the `search` variant's slot
|
|
* [data-md-app-bar-trailing] [data-md-app-bar-action], [data-md-app-bar-overflow]
|
|
* [data-md-app-bar-expanded] medium/large's big title, under the row
|
|
*
|
|
* small 64px, title-large title (label-medium subtitle), 4px from the edges, the title 16px
|
|
* from the start or straight after the navigation icon
|
|
* center the same, the title centred — a three-column grid, so it shrinks against whatever is
|
|
* beside it rather than ellipsising underneath it (N-11: a fixed inset fit exactly one
|
|
* of M3's two trailing buttons)
|
|
* medium 112px (136px with a subtitle): the 64px row of icons over a headline-medium title
|
|
* large 120px (152px with a subtitle): a display-small title
|
|
* search the row holds a search bar, full width to 312px and then half of what is left (N-09)
|
|
*
|
|
* The container is the surface, and surface-container once content scrolls under it. A medium or
|
|
* large bar collapses into the small one without script moving anything: the bar is sticky at a
|
|
* negative top, so it scrolls up until only 64px of it remain, while its row of icons is sticky at
|
|
* 0 inside it and stays put — the big title scrolls away under the row. Script only says when that
|
|
* has happened (resources/js/app-bar.js), so the small title can fade in and the colour change.
|
|
*
|
|
* Trailing actions given as a list collapse into an overflow menu below `medium` and come back
|
|
* from it, by media query alone (the site's "trailing actions collapse into an overflow menu at
|
|
* smaller breakpoints" and "become visible again at larger sizes", read together with "up to two
|
|
* icon buttons" and, for a wider window, "up to four trailing icons"): both forms of every action
|
|
* are in the page, and each width hides the one it does not use, so nothing flashes and no script
|
|
* counts.
