 * than in the partial because none of what follows is expressible as a
 * utility: two pseudo-elements (the caret and the invisible hover bridge that
 * lets the pointer cross the 14px gap), ancestor-state descendants
 * (`.mega:hover .mega-panel`), a `:not(:first-child)`, and a max-width media
 * query — Crosswind emits nothing for any of them. The leaf styling that IS
 * expressible (.mega-t, .mega-d, the panel links, the menu group's own box)
 * became utilities in the markup and is deliberately absent here.
 *
 * A linked stylesheet is also the router-safe home: the SPA router destroys
 * every <head> style that is not the Crosswind tag on navigation.
