/*!
 * MM Babel — front-end stylesheet
 *
 * Provides minimal, theme-agnostic styling for the language switcher
 * shortcode and its widget wrapper. Uses BEM-like class names, scoped
 * under `.mm-babel-switcher`, so themes can override individual hooks
 * without resorting to !important.
 *
 * Inherits color and font from the surrounding context where possible.

/* Note on colour scheme: prefers-color-scheme is intentionally NOT used.
   The switcher follows the site's own theme — colours and surfaces are
   driven by `color: inherit` on text and explicit defaults (white
   dropdown, dark text) for the panel. Themes that ship a dark palette
   override the dropdown surface via their own CSS rather than fighting
   the OS preference, which previously caused the dropdown to render
   dark on top of a light site whenever the visitor's OS was in dark
   mode. Removed in 0.9.1 after the chaodarelva live test. */
