/* Cefrite Site Motion kit — draft 2026-10-26 (vibe / funnel pass)
   Soft Hybrid T1 whoosh/ping. Alive, not sterile. No bounce/pulse cliffs.
   No cyan. Amber synced to dual-world --cf-accent.
   Home/Explainer/Founder: whoosh + glow CTAs + optional one ping.
   Science / Roadmap: cm-lane-science (reveals + soft lift; no ping/glow).
   Wire with Web Coder; Sascha deploys. */
