{{-- 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. `<x-tabs>` renders
     this slot before its own view, so it cannot hand the panel anything; the panel reads `tabs`,
     `id` and `selected` off the component stack with `@aware` and rebuilds tabs.blade.php's id and
     initial tab from them (Support\Field::bound for the initial, since `wire:model` is not a
     `@props` value `@aware` can read). The two must agree, so change them together.

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