{{-- M3 Expressive's toolbar: a set of actions for the current page, in a bar of its own.

     `variant`: `floating` (the default: a pill at elevation 3; `vibrant` in primary-container,
     `vertical` stands it on end) or `docked` (a full-width bar in surface-container, for the bottom
     of a screen). `place` puts it over the page: `bottom` (centred above the bottom edge; a docked
     toolbar spans it) or `end` (centred against the end edge, for a vertical one); without it the
     toolbar sits where it is written. A `fab` slot sets an `<x-fab>` beside a floating toolbar,
     and at the end of a docked one — M3's "With FAB" configuration for both. On a docked toolbar the
     controls then gather at the start and the FAB rests on the bar, flat: M3 gives a FAB nested in
     another component elevation 0 (Compose's bottomAppBarFabElevation is 0 at every state), where
     one beside a floating toolbar keeps its own. It is one of the toolbar's controls then, so the
     arrow keys reach it. `label` names it for screen readers.

     `rounded` gives a docked toolbar the form M3 lets it take on web and large screens: "the docked
     toolbar can be rounded. Dividers can be used to organize large amounts of items", and it "can be
     … placed in different parts of the page" (docs/reference/m3/components-navigation-selection-inputs.md
     § Toolbars → Behaviour and guidelines). From `expanded` (840px) it is a fully rounded bar that
     spans what it is written in, and at `place="bottom"` it lifts clear of the window's edges; below
     `expanded` it is the square, full-width docked toolbar, as M3 requires there. Separate groups of
     controls with `<x-divider vertical />` between them (in a vertical toolbar, `<x-divider />`):
     inside a toolbar it stands as tall as an icon button rather than across the whole bar. The
     floating toolbar has no such form — it is fully rounded already, and M3's large-screen advice
     for it is to show more controls, or two toolbars at opposite edges.

     A docked toolbar and a navigation bar occupy the same region of the screen and M3 says never to
     show both at once: the bar belongs on a primary page, the toolbar on a secondary or contextual
     one. Either way a toolbar placed at `bottom` clears `--material-bottom-bar`, so it is never
     buried under `<x-scaffold>`'s bar.

     Put `<x-button icon="…" tooltip="…" />` controls in the slot (`:selected` for toggles). It is a
     `role="toolbar"`: the arrow keys move between its controls (resources/js/toolbar.js,
     resources/css/components/toolbar.css).

     The toolbar renders `data-md-toolbar` with `data-md-variant`, `data-md-vertical`,
     `data-md-vibrant`, `data-md-rounded` and `data-md-toolbar-place`; a FAB beside a floating
     toolbar sits in `data-md-toolbar-group` (with the toolbar itself), one docked in
     `data-md-toolbar-fab`. Drawn by resources/css/components/toolbar.css, which the view renders
     no other component into — a caller's own `<x-button>`, `<x-fab>` and `<x-divider>` bring
     their own stylesheets. --}}
