/* ───────────────────────────────────────────────────────────────────
   Amble — site stylesheet
   Two layouts share this stylesheet:
     • Marketing landing page  (body class: page-marketing)
     • Legal/document pages    (body class: page-doc)
   The shared elements (brand mark, colour palette, footer) live at the
   top; layout-specific styles further down.

   Design philosophy: warm, sage-green palette echoing the app icon.
   Avoid the sterile Stripe/Linear "tech corporate" white. Amble is a
   lifestyle/wellness brand — this should feel closer to a walking
   magazine than to a SaaS pitch deck.
