/* ==========================================================================
   LP03 · UNIT 9 · PROVEN TECHNOLOGY + BECOME A FOUNDING MEMBER
   --------------------------------------------------------------------------
   One section, two tones:
     A · light top  — "Proven Technology. A Better Way Forward." The three
         foundations the copy names stand as pillars under a beam that
         carries the Fatorly mark (the "way forward" rests on them).
     B · navy band  — "Become a Founding Member": a certificate card
         overlapping a bisht photo, its benefits as icon chips, and a
         Founding Member stamp that presses onto the paper.
   prv.js: pillars rise, beam lands; then certificate slides in and the
   stamp presses. Without motion everything is shown in place.
