/* ── Mobile overlap fix (2026-10-14) ──
   On phones the fixed nav and the sticky sub-nav were only 70% opaque, so section headings
   scrolled visibly behind them. The full-viewport grain layer also used mix-blend-mode, which
   mobile Safari can render as overprinted text near the toolbars. Make both bars solid enough
   to hide content and drop the blend on small screens. */
