/* KinCare web — shared neumorphic base.
   Mirrors the app design language (docs/kincaredesignva.md): soft raised/inset surfaces on one
   base colour, paired shadows, status-only colour, big targets. Loaded by every page BEFORE the
   page stylesheet (home.css / legal.css / delete.css).

   Depth = affordance:  raised = tappable · inset = field/track/finished · flat = info only.
   Shadows are always a dark+light pair painted on the SAME colour as the page (--bg). */
