   Menus & popovers   Alpine x-data="menu" (or "popover") with [data-menu-trigger] + [data-menu-panel].
                      Panels are Popover-API elements in the top layer, positioned by app.js.
                      .menu__panel (--wide) · .menu__item (--danger, [aria-checked] check marks,
                      __icon/__text/__kbd/__check) · .menu__label · .menu__sep · .menu__header ·

   Tooltips           data-tooltip="Text" [data-tooltip-pos="bottom|left|right"] (CSS only, hover devices)
