<x-search> renders data-md-search with data-md-trigger and binds data-md-open and data-md-full-screen; its parts become data-md-search-* and the empty row data-md-search-empty. search.css moves into material.components on px, spacing and state tokens (plan step 36). search.js and the showcase layout follow the renamed hooks. Browser tests cover the polite result count as it changes, the icon entry point expanding full screen and returning focus, and suggestions swapping to results on the first key.

/*
|
|
* M3's search: a search bar that opens into a search view (SearchBarTokens, SearchViewTokens,
|
|
* androidx Compose Material 3, Apache-2.0).
|
|
*
|
|
* The bar is a 56px pill in surface-container-high: a leading search icon, the input in
|
|
* body-large, a clear button once something is typed, and whatever the caller trails it with (an
|
|
* avatar, an icon button). Focus opens the view. On a medium or wider window the view is docked
|
|
* over a scrim: the bar grows down into an extra-large-cornered container at elevation 3 that
|
|
* holds the results. On a compact window it takes the whole screen, and the search icon turns into
|
|
* a back arrow. `docked` keeps it docked at every width.
|
|
*
|
|
* Widths are M3's: never wider than 720px, and the bar grows to that width while it is focused —
|
|
* `--search-width` is its resting width (the room it is given, by default) and
|
|
* `--search-open-width` the focused one, so a caller that wants M3's 360px resting bar sets
|
|
* `--search-width: 360px` on a wrapper. The leading and trailing padding is 24px unfocused and
|
|
* 16px focused, as the search specs table gives it.
|
|
*
|
|
* Hovered and focused buttons in the bar take M3's state-layer opacities (tokens/state.css), and the
|
|
* docked scrim is M3's scrim role at 32%, which no system token names. The breakpoint that makes the
|
|
* view full screen is decided in resources/js/search.js (`upTo('medium')`, 600px).
|
|
*
|
|
* [data-md-search] the root; data-md-open, data-md-full-screen, data-md-trigger
|
|
* [data-md-search-scrim] over the page while the view is docked
|
|
* [data-md-search-trigger] data-md-trigger="icon" only: the icon button that expands the view
|
|
* [data-md-search-bar] the pill, above the view
|
|
* [data-md-search-leading], [data-md-search-field] (the combobox around
|
|
* [data-md-search-input]), [data-md-search-clear], [data-md-search-trailing]
|
|
* [data-md-search-view] the container behind the bar
|
|
* [data-md-search-suggestions] before the first keystroke
|
|
* [data-md-search-results] once something is typed; [data-md-search-empty] when nothing is
|
|
* [data-md-search-status] the polite live region that counts whichever list is on screen
