v0.21.0 — About page catch animation, 3-step sequence, pull-quote

Demo-prep polish: recreates the visual sections from the original design
handoff that were never built out in production —

• A looping "catch" animation: three opportunity chips fall into a mitt
  with a squash-and-stretch catch, a ring burst, and a cosmetic "+1 caught"
  counter.
• A 3-step, no-prose explainer (📵 😤 📡).
• A pull-quote panel.
• Team section upgraded with the design's humor taglines, keeping the real
  photos added in v0.20.0.

Existing intro paragraphs kept as-is.
