/*
  Expressive layer. Loaded after the Webflow CSS and embeds.css, so it only
  restyles layout, type and motion; page structure and copy are unchanged.

  Motion is one system: a single easing and duration, and only opacity and a
  short rise, so nothing competes with the headline letter reveal. Reveals
  only apply once MotionLayer has added .fx-on to <html>, so without
  JavaScript or with reduced motion everything shows as normal.

  Sizing aims for several things per screen: banners and blocks are capped
  well below the viewport height so the next section always peeks in.

   Scale follows what established studio sites use (Pentagram, Collins,
   MassiveMusic, Antfood): body 16–19px, headlines 40–60px, section titles
   28–40px, small uppercase labels. Only the logo is oversized. */
