/* ============================================================================
   Typography — opinionated baseline + helper classes
   ============================================================================
   Applies the design-token type scale to standard semantic elements and
   provides utility classes for components.

   Existing style.css already defines `body { font-family }` etc., so this
   file is layered on top — token-driven and gentle. Components in
   modules/core/components/* should prefer these helpers over inline
   font-size declarations.
