/**
* `<lr-tab>` — one tab in a `<lr-tab-group>`'s strip. Mirrors `wa-tab` / `sl-tab`.
*
* A declarative descriptor, not the interactive control: `<lr-tab-group>` renders the real
* `role="tab"` button and projects this element's content into it, so the whole ARIA and
* roving-tabindex contract stays in one place. That means the content may be rich (an icon plus a
* label, a badge), but its direct element roots are inert while projected so the button remains the
* sole action. The group's real button gets only the default slot's accessibility-exposed flattened
* text as its accessible name; author-hidden, inert, or CSS-hidden branches do not contribute.
*
* Pair it with a `<lr-tab-panel>` whose `name` matches this element's `panel`.
* `closable` adds a localized visual close affordance. It shares the owning tab's single APG focus
* stop rather than nesting another interactive control inside the group's real tab button: click
* the affordance, or press Delete while the real tab button is focused. Either path emits the
* noncancelable `lr-close` notification without selecting or removing the tab; the owning
* application decides whether and when to remove the matching tab and panel.
*
* @customElement lr-tab
* @slot - The tab's visual label content. Its direct default-slot element roots are inert while the
*   owning group projects them; their accessibility-exposed flattened text names the real tab button.
* @event lr-close - Emitted when the close affordance is clicked or Delete is pressed on its
*   focused owning tab. Bubbles, is composed, and is not cancelable; the component does not remove
*   itself.
* @csspart base - Compatibility name for the tab content wrapper; use `tab`.
* @csspart tab - The tab content wrapper. It is the same node as `base`.
* @csspart close-button - The non-focusable visual close affordance shown when `closable` is true.
* @csspart close-button__base - Compatibility alias on the same close affordance as `close-button`.
* @status stable
* @since 8.0.0
