One probe page per claim: an application's unlayered .app-wide rule beats
button.css's layered inline-size and padding; [hidden] beats a component's
display on both <x-row> and <x-button>; the layer order holds when
Stylesheets::bundle() serves button.css before foundation.css, so the
reset's padding: 0 still loses to the button's own; a data-md-variant
attribute updates correctly through the same re-render/morph a plain
wire:click="$refresh" drives, toggled both ways; <x-icon mirror-rtl> mirrors
under dir="rtl" and does not under dir="ltr". Chromium: 6 assertions, all
green, alongside ShowcaseTest.php (5 tests, 18 assertions).
