/* Minimal fixed-position language pill — top-right, single link.
   No topbar/footer exists on this LP (pure single-column story), so this
   follows the same "fixed, minimal chrome" precedent as .b-sticky rather
   than a masthead nav. Reads window.LP_LANG directly (set per entry point
   in index.html / en/index.html) so it needs no props.
