/* ============================================================================
   RISKORA — /learn article styles
   ----------------------------------------------------------------------------
   Shared by every guide page under /learn. Built on the same --rk-* tokens the
   rest of the site uses (css/riskora-tokens.css) so a guide never drifts from
   the product's look, and so the light/dark toggle in js/riskora-theme.js works
   here with no per-page code.

   These pages exist to be found in search and read once, carefully — so the
   type is set for reading (longer measure, larger body) rather than for
   scanning like the dashboard.
