/* DMARCS Learning Center: shared stylesheet.

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

   Layout mirrors the Help Center: one module per page
   (learning.dmarcs.com/<tier>/<slug>/), a left rail with the tier's module
   list, and a reading column capped at 720px. The tier/module/quiz
   components at the bottom of this file are new; everything above them is
   the same component set as help.css so the three DMARCS sites read as one
   family.

   Referenced everywhere as learning.css?v=N. Bump N in every HTML file
   when this file changes. */
