{{-- One tab's panel, inside `<x-tabs>`, which draws the bar from its own `tabs` list. Shown while
     its `name` is the chosen one; every panel is rendered, so switching never waits on the server.

     The id and the `hidden` panels come from the server, not from Alpine: until Alpine boots, every
     panel would otherwise be on screen at once — four `role="tabpanel"` regions for a screen reader
     to walk — and the tab buttons' `aria-controls` would point at nothing (N-05). `<x-tabs>` renders
     this slot before its own view, so it cannot hand the panel anything; the panel reads the
     attributes written on `<x-tabs>` off the component stack (Blade's `@aware` mechanism) and
     repeats the two lines tabs.blade.php runs on them. The two must agree, so change them together.

     The panel renders `data-md-tab-panel`, drawn by resources/css/components/tabs.css. --}}
