/* ============================================================
   Authyr — long-form document layer (the whitepaper).

   Styles the whitepaper's OWN existing class names (.doc, .chap,
   .chap-title, .callout, .pq, .stack-item, .tf-row …) in the premium
   design language. Written this way deliberately: the whitepaper carries
   the canonical thesis, and CLAUDE.md marks that text SACRED — so the
   markup and wording are left byte-identical and only the presentation
   moves. Pair with authyr-premium.css.
