/* ===================================================================
   Terri Mercantino — Massage Therapy in Princeton, NJ
   Stylesheet — Lavender Twilight
   ------------------------------------------------------------------
   Palette: aromatherapy-inflected lavender. Pale lilac ground, deep
   purple-black ink, mid-lavender accent with a warm-amber humanizing
   note. Dignified, sensory, calm — never spa-pastel. WCAG 2.1 AA
   contrast on every text/background pair. Designed for the unhurried
   pace of bodywork.
