/* ───────────────────────────────────────────────────────────────────────────
   Disney's New AI Knows What Ride You Want. Page styles for the patent-watch
   Paper Trail feature. Rides on top of paper-trail.css (the hero, docket, beats,
   rail, coda, receipts and FAQ chrome are all shared). This file adds the editorial
   prose rhythm and the two bespoke interactives, the engagement-curve explorer and
   the "Dave vs the metamodel" speed race.

   Tokens (--gold, --hair, --pt-panel, --pt-gold-line, --pt-gold-faint, --pt-stamp,
   --space-*, --display, --text, --label) are inherited from .guide--papertrail.

   Every <p>, <li> and <blockquote> rule is scoped under .guide--metamodel (two
   classes) so it outranks the base `.guide p` rule (0,0,1,1) in site.css, which
   would otherwise flatten this copy back to the generic guide body style.
