/* Encino Center for Sleep and TMJ Disorders
   Visual system: fluid type, dark-navy/white/light-blue alternating sections,
   rounded fill-hover buttons, restrained motion. Design language adapted from
   the agency's Perio Providers Group demo (colors, type scale, section rhythm,
   button treatment) — implemented fresh for this site. */
