/* DMARCS Help Center — shared stylesheet.

   Same brand tokens as the Trust Center (dmarcs-trust-center/trust.css),
   pulled from the live www.dmarcs.com, not the admin app's own theme - this
   folder is hosted on the marketing site, not the app.
     --color-primary   #1565C0   (CTA buttons, links, "Get Started")
     --color-secondary #6AACFE   (secondary CTA, light accents)
     --color-heading    #0F1926   (headings on light sections)
     --bg-hero          #0D3B6F   (dark hero/section background)
     --bg-light         #EAF3FF   (light section background)
     --color-body        #403A56   (body copy)
   Fonts: Plus Jakarta Sans (headings), Inter (body). Buttons pill-shaped.

   Structural pattern (hero search bar, category card grid, category banner
   + breadcrumb + "in this category" sidebar) modeled on real Zendesk-style
   help centers (KnowBe4 Knowledge Base, Mimecast Support) at the user's
   request - the layout convention visitors already expect from a help
   center, not a from-scratch design.
