 * Popover component.

 * - anchor: positioned relative to an anchor slot element
 * - floating: manually positioned via top/left/bottom/right properties
 *
 * For anchor mode, the popover will be positioned relative to the anchor element
 * based on the direction property. The position can be fixed or absolute.
 *
 * For floating (manual) mode, set triggerType="none" and use top/left/bottom/right
 * properties to position the popover.
 *
 * @slot unnamed - The main popover slotted body content
 * @slot anchor - The trigger element (icon, button, link, etc.)
 * @slot footerLink - Optional link to be displayed in the footer
 *
 * @fires on-close - Emitted when any action closes the popover.`detail:{ action: string }`
 * @fires on-open - Emitted when popover opens. `detail:{ origEvent: Event }`
