/*
  FXBALL marketing landing page (/)
  Builds on the app's existing token system (style.css) rather than
  inventing a second palette. Visual language: stadium floodlight at
  night — near-black pitch, one accent (the brand green) doing all the
  work, angled kit-collar cuts instead of rounded SaaS cards, scoreboard
  display type for headlines and numbers.

  Motion: one orchestrated hero entrance on load, a scroll-triggered
  reveal for everything below the fold (driven by landing.js toggling
  .is-visible on .mk-reveal elements via IntersectionObserver), and a
  small set of idle/ambient touches (floodlight glow breathing, the
  mini-card stack drifting) that only run under prefers-reduced-motion:
  no-preference.
