/* ============================================================
   DIRECTION: Light Airy — Sylvia A. Gisi, M.D.
   White base, one saturated accent taken from the practice's real
   logo (teal #4A96BA, deepened for contrast), split hero with a
   contained rounded media panel, soft tinted wash, rounded tiles.

   NOTE: this page deliberately does NOT follow prefers-color-scheme.
   An OS dark-mode setting was silently repainting the light
   directions dark, which defeats the point of a light design for a
   medical practice. The [data-theme] blocks still allow an explicit
   toggle.
