/*
  Landing intro (components/landing_intro.html + js/components/landing-intro.js).

  Plain CSS on the Basecoat theme tokens instead of Tailwind utilities, so the
  intro can change without a CSS rebuild and follows light/dark automatically.

  The scene is drawn on a fixed 880×500 canvas that JS scales to fit the hero,
  like a video frame: every beat looks identical at every screen size, which
  is what makes "beat 3 at 0:06" a reliable thing to point at.
