/* STRANGEPAIR MARKETING SITE — public front door (DIR-037, phase c).
   Built on the ratified canonical module: consumes /shared/tokens.css (mobile-
   first fluid scale), /shared/mark.js (the two-face glyph), /shared/footer.css +
   footer.js (the one canonical footer), and the seam primitives (--seam / .sp-*).
   This file is the SITE'S OWN chrome only — hero, sections, audience cards, the
   public header — never a parallel token set. Dark theme, mobile is the floor.

   §C discipline: NO tracked-out all-caps mono eyebrows here (that pattern stays
   inside /styleguide). The public surface stays clean and quiet; the one bold
   moment is the hero seam split (§F). */
