/* =============================================================
   LAUNCHWISE LANGUAGE SWITCHER — production
   Styled against the existing Launchwize design tokens
   (--line, --line-2, --text, --ink-50, --accent, --r-2, --paper).
   Falls back to safe defaults if tokens are absent.

   Components:
   - .lang-switcher          wrapper around the dropdown trigger
   - .lang-current           trigger button (shows the active lang code)
   - .lang-menu              the popup list (positioned absolute)
   - .lang-switcher-mobile   inline links used inside the mobile menu
