/* =============================================================================
   base.css — shared structure + components for CQuence / Cassling focused sites
   -----------------------------------------------------------------------------
   Brand-agnostic. Contains ZERO brand color literals — every color is a token
   (var(--color-*)) supplied by a theme file. Always load a theme alongside it:

       <link rel="stylesheet" href="base.css">
       <link rel="stylesheet" href="theme-cquence.css">   <!-- or theme-cassling.css -->

   This :root block defines only brand-NEUTRAL primitives (spacing, radius,
   type, shadow, motion). The theme file defines the palette. Order-independent.

   Body font is Lato (matches www.cquencehealth.com / www.cassling.com), pulled
   from Google Fonts below. For CSP-locked sites that block external requests,
   delete the @import and self-host Lato, or drop 'Lato' from --font-sans to
   fall back to the system stack.
