/* ===========================================================================
   Helix — stress-test landing page styles.
   Design system: warm editorial paper base + one committed electric coral,
   mono accents. Deliberately maximal: canvas hero, parallax, scroll-reveal,
   marquee, tilt, carousel, sticky shrink-nav. OKLCH throughout.
   All of this lives in code (this file). The client edits text/images via
   native blocks; these effects are developer-owned.
