   Weaion Labs — motion study E · kinetic
   Warm paper, near-black ink, one vermilion. Instrument Serif at poster scale
   over Geist. The motion is editorial rather than technical: masks, clips,
   a photograph that grows to full bleed, cards that stack, a hover image that
   chases the pointer.

   References studied: Obys and Uncommon Studio (type as the hero), Mat Voyce
   (kinetic type), By-Kin (weighted scroll, restraint), Awwwards GSAP winners.

   Content is visible by default. Hidden starting states live under .js-ready,
   which kinetic.js sets only after the animation exists.
