/* ── HISS "Win a free class" popup — 2026-10-20 ──────────────────────────
   Homepage-only promo popup. Appears once, 7s after page load, and is
   suppressed forever after (localStorage flag set the moment it's shown,
   in index-popup.js) — so a repeat visit, or navigating back to the
   homepage from another page, never shows it again, whether or not the
   visitor actually closed it.
     --hiss-blue   #0936b4
     --hiss-red    #b31812
     --hiss-yellow #ffcd45
   Font is Raleway (already loaded site-wide). */
