Plan step 38 review: the component sections' code samples, which an application copies, carried 60 data-md-showcase-* hooks that only showcase.css draws (a sized loading indicator, the plain badge's own colours, a bordered bar frame, the navigation demos' frames, a table's scroll wrapper...), so a copied sample did nothing in the application. They now write what an application has: <x-surface outlined corner> for a frame and a line, <x-row> for the FAB menu's corner, and an inline style from the tokens for a size, a scroll box or a colour, as the Containment batch already did. The side sheet demo takes align="stretch", which holds in both of <x-row stack-below>'s modes, instead of a hook that undid align="start" once stacked. The menu icon colours go through icon-class with two unlayered application-like classes, which the sample's comment names, and the fields' and date picker's widths are inline styles now that style reaches their roots. The radio hint said "from sm"; it is medium. showcase.css keeps only the frame and the foundation specimens; its header describes the file instead of the batches that wrote it. The tests reject a showcase hook or a class outside md-* and the named application classes in any example, a showcase.css selector outside its own hooks, and a hook no showcase view renders.

* The showcase's own chrome: what its pages draw beyond the layout components, the `md-*` text
|
|
* classes and the shared interaction classes (plan step 38) — the rail's wordmark, the search box
|
|
* and its results, a keyboard key in running text, an example's card and its code sample, and the
|
|
* foundation pages' specimens: a colour swatch, a type-scale row, a corner swatch, an elevation
|
|
* tile, a motion track and its dot, an icon search result and the Layout page's breakpoint cards.
|
|
*
|
|
* Only the showcase's own pages use it. The examples do not: an example's code is what an
|
|
* application copies, so it writes only what an application has — the components and their props,
|
|
* the layout components, the text classes, and an inline `style` from the `--md-sys-*` tokens where
|
|
* a demo needs a size, a frame or a colour of its own.
|
|
*
|
|
* In `material.components`: the showcase is one more page drawn over the foundation and the layout
|
|
* components, where `components/error-page.css` sits for the same reason, and an application's
|
|
* unlayered CSS still outranks it. Keyed on `data-md-showcase-*` hooks, never a bare element
|
|
* selector, since `ShowcaseAssetController` bundles this file with `all.css` and it must restyle
|
|
* nothing outside those hooks. It imports nothing: every token and layout rule it builds on is in
|
|
* `all.css`, ahead of it in the bundle. Values are tokens, apart from a specimen's own size; its
|
|
* media queries are M3's breakpoints, in px.
|
|
*
|
|
* Two kinds of rule sit outside the layers on purpose, as an application's own classes would:
|
|
* `.showcase-w-narrow` proves the point its example makes (Text fields, "Narrower": an unlayered
|
|
* rule from the call site beats the package's layered default, which an inline `style` would win
|
|
* regardless of layers, proving nothing), and `.showcase-ink-*` are the colours the Menus example
|
|
* passes to `icon-class`, the application's own class that prop takes.
