/* ==========================================================================
   Ananta Designs - base layer

   Reset, document defaults, typography and the small set of utilities the
   templates lean on. Ported from the prototype's globals.css, with the
   Tailwind layer removed: production is hand-written CSS so the stylesheet
   ships at a few kilobytes rather than a framework's worth.
