/*
 * The showcase's own chrome: what its frame needs beyond the layout components, the text classes
 * and the shared interaction classes (plan step 38) — a brand wordmark, the search box's own
 * geometry, a small icon avatar, an example's card and its code sample. Everything else the frame
 * draws is a layout component with its props, or a `md-*` text class; this file is only what those
 * two do not cover.
 *
 * In `material.components`: the showcase is one more thing drawn over the foundation and the
 * layout components, exactly where `components/error-page.css` sits for the same reason (a whole
 * page's own chrome, not a reusable package component, but still something an application's own
 * unlayered CSS should outrank without a specificity fight). Keyed on `data-md-showcase-*` hooks,
 * never a bare element selector, since this file is always bundled together with `all.css`
 * (`ShowcaseAssetController`) and must not restyle anything outside the showcase's own pages.
 *
 * No imports: batch 1 (the frame — layout, index, section, shell, the example component) uses no
 * selector this file needs to draw over, only tokens already in `all.css`, which the bundle always
 * carries ahead of this file. A later batch that needs a component's own hook imports its
 * stylesheet here, as every other package file does.
