/* Beacon — shared design tokens & chrome (nav, footer, buttons, badges,
   rank-check mock component). Page-specific sections live inline in index.html.
   Same dark-SaaS family as the other Local Logic Management case studies, with
   Beacon's own identity: a warm "beacon" gold cutting through deep night-navy,
   plus teal/coral as semantic up/down signal colors for rank movement. */
