{{-- M3 Expressive's navigation rail: destinations down the start edge of a `medium` or wider
     window, collapsed (96px, icon over label) or expanded (icon beside label in a full-width
     pill). `mode`, props, slots and `$store.rail` are documented in SKILL.md.

     Anything else inside the rail queries `--md-navigation-rail-value` (SKILL.md has the pattern
     and an example); the rail's own two rules (resources/css/components/navigation-rail.css) are
     what publish it, so every other rule just queries it instead of copying the rail's own
     conditions. tests/Feature/Components/NavigationRailTest.php checks both halves.

     As the rail closes it keeps `data-md-closing` (`sheet` while the panel slides off the window,
     `scrim` while only the scrim fades) until the exit has run: Firefox cannot transition
     `display`, so this is what holds a closing rail on screen there (resources/js/navigation.js).
