/* John H. Cho, DDS — demo redesign.
   Teal sampled from the clinic's own operatory photo (TV screen, dominant
   bucket #105050 / dark-teal average #115553): primary #0F4F4E.
   Logo file + exact CSS palette could NOT be read — live site bot-blocks
   curl, Wayback 429 — so the header uses a text wordmark, flagged in the
   deliverable. Square corners throughout. Radius: 0. No shadows.
   Type scale (5 sizes only): 44 / 30 / 20 / 16 / 14.
   Spacing scale: 4 / 8 / 16 / 24 / 32 / 48 / 64. */
