/*
  Simify Partner Brief Hub - shared design system
  Applies to: hub home, blog brief, video briefs (longform/shortform), assets, links, per-partner pages.
  Tokens captured from brand-guidelines skill + live partner-longform.pages.dev / partner-shortform.pages.dev
  (white background, blue accents, sans-serif, star value-prop banner, 5-step horizontal flow, sticky logo top-left).
  No build step. Vanilla CSS only.
*/

/*
  Font stack: brand-guidelines specifies Rubik (primary) + Crimson Text (secondary
  italic), but this build is a free-tier, self-contained, no-CDN static site, so
  we do not load web fonts from a CDN. The stack below names Rubik / Crimson Text
  first (in case they are ever installed locally or self-hosted later) and falls
  through to close system equivalents: a geometric/grotesque sans for Rubik,
  a serif for Crimson Text italic.

  that these live values win over the aspirational Section 1 palette for any
  partner-facing artifact, so every color below is the live token, not the
  aspirational one, except where the two already agree.
