/*
 * 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.
