/* ── language toggle (EN · RU) ─────────────────────────────────────────
     A flat pill in the hero's top-right corner, the same material as the
     ambient-audio toggle: #F2F2F2 fill, 1px #EBEBEB hairline, fully rounded,
     no hover lift / shadow. It carries two segments — EN · RU — with the active
     language inked solid and the other dimmed; a tap flips them. Fixed so the
     guest can switch language from anywhere on the page; it fades in with the
     hero exactly like the nav. */
