/* PGP PRO Co'27 — "annotated notebook" design system.
   Language taken from the ME Session 1 interactive: Literata serif body,
   Caveat cursive display, Patrick Hand labels, IBM Plex Mono figures;
   paper ground, ink-navy text, red/green/blue annotation accents.
   Pages load: Caveat:wght@500;700, Literata (opsz 7..72, 400/600/it),
   Patrick Hand, IBM Plex Mono:wght@400;600 from Google Fonts.
   The tote (site/tote/) does NOT link this file and keeps its own look. */
