/* ITEX Owner's Guide — shared stylesheet for all grow.itex.com pages. One file,
   edge-cached across every page.

   Design system (D-021): token layer + typography (ITX-68), designed section
   components with alternating full-bleed bands (ITX-69). Barlow (open-license
   DIN-style, self-hosted latin subsets, SIL OFL — assets/fonts/OFL-Barlow.txt)
   carries headings; body stays on the system stack. Barlow stands in for
   Bahnschrift until ITEX resolves licensing (ITX-56); swap = one token.

   Brand: charcoal carries text + primary buttons (WCAG AA); the bright brand
   green/blue are ACCENTS ONLY — arcs, borders, badges, icon strokes — never
   small-text colors (constitution/marketing/brand.md). Hex values are web
   approximations pending exact PMS swatches (ITX-56). */

   the first viewport (.pre-reveal) and reveals them once on entry (.revealed).
