{{-- M3's window size classes, live: the one this window is in, what each one changes, and the
     variants that key on them. The five cards light up through the variants themselves, so the
     page proves the compiled breakpoints rather than describing them. --}}

        Widths are M3's window size classes and nothing else: compact below 600px, then <code>medium:</code> 600,
        <code>expanded:</code> 840, <code>large:</code> 1200 and <code>extra-large:</code> 1600, with
        <code>max-medium:</code> and friends for "below". Tailwind's <code>sm:</code>…<code>2xl:</code> compile to
        nothing. Scripts read the same numbers from <code>resources/js/breakpoints.js</code>.

        <code>&lt;x-app-shell&gt;</code> does all of this: resize this showcase and watch the bar, the rail and the
        content margin (<code>--material-margin</code>) change at 600, 840 and 1200px. A visitor who has chosen a rail
        width keeps it; until then the rail follows the class.

            M3 describes a layout as a scaffold of bars and rails around panes, and names three canonical layouts. These are
            those words as components, each taking <code>as</code>, <code>hide-below</code> and <code>hide-from</code>, and
            only the spacing tokens for a gap or padding:
