/*
  Merchant Rate Auditor — Resources / Merchant Fee Guides (SEO content
  section).

  Shared by public/resources.html (hub) and every /resources/<slug>.html
  article page. Deliberately reuses the SAME dark-navy/gold visual
  language and class names already established by public/landing.html
  (--navy/--gold tokens, .lp-wrap/.lp-nav/.lp-footer* markup) rather than
  inventing a second design system — this IS the public marketing site,
  just a second page family within it. Pages that load this file also
  load /css/customer-shell.css first (for the shared .mra-root reset,
  --font-mono, and the base .btn geometry landing.html itself depends on)
  — this file only adds the nav/footer restatement plus new, additive
  ".res-*" classes for hub cards and article typography.

  Nothing here is referenced by, or changes the appearance of, any
  authenticated app page (index.html, statement-review.html, the owner
  command center, etc.) — those load their own stylesheets and never
  this one.
