/* ============================================================
   CannabisForSeniors.org — Sage Trust Theme
   ============================================================
   Calm sage-green palette with warm-cream backgrounds. Tuned
   for older readers: slightly larger body text, higher contrast,
   tighter line-height for scannability. Inherits typography and
   layout primitives from base.css.
