Plan step 38 (last batch): the navigation-bar and navigation-rail
demos' bounded frames become data-md-showcase-nav-demo (`bar`,
`bar-wide` inside its own data-md-showcase-nav-scroll wrapper, `rail`,
`rail-wide`), the "the page" filler is data-md-showcase-nav-page and
the content pane beside a rail data-md-showcase-nav-content; a group
of demos moves onto <x-row>/<x-stack> with inline max-width styles for
the two arbitrary demo widths (400px, 800px) Tailwind's arbitrary
values gave them. The "Open the scaffold" link's md-link/md-ink-primary
classes match bars.blade.php's.
Every #navigation id, aria-label and visible label the Chromium
NavigationTest (against its own probes and /material/shell) relies on
is unchanged.
