/* ============================================================
   BUILT FOR · audience positioning section
   "Is Tokverse Studio built for me?" — premium glass cards, 3/2/1 grid,
   soft float + ambient glow + 3D tilt + light reflection. Continues the
   white premium design language; fades into Pricing.
   Reusable: cards render from data (audience.js). Reuses .an-rise system.
   Requires: base.css, post-wf.css (for --ease-film / .an-rise)
