/* =============================================================================
   ShiftHawk — Buddy match section (vanilla CSS, no dependencies)
   The "ForeSIGHT finds shifts that put you both on the same day" pitch.
   Shares the visual language of the Team-invite stage (team-invite.css):
   a .stage card with a mono caption, an animation body, and a .stage-foot
   beat. Pairs with assets/js/buddy-match.js, which plays a scroll-triggered
   sequence (IntersectionObserver) and serves a static composed state under
   prefers-reduced-motion. Reuses the design tokens from styles.css.
