/* Layout concept: an expo-floor lanyard — each founder is a badge (green strip, name, company, role) laid out in the
   order of the day; the founder page opens with that badge, then the conversation beside its transcript.
   House palette: navy + one green; heartbeat line from the Friends of Kevin outro as the only ornament. */
