/* ---------------------------------------------------------------
   Northline Family Dental — concept build, invented practice.

   A different job from Raajbhog. That site sells atmosphere; this one
   sells trust and ease. Someone finds it on a phone, often in pain or
   long overdue, and needs three things fast: what this place does,
   where it is, and how to get an appointment. Everything here serves
   that, and anything that got in the way of it was cut.

   No webfonts. A dental site that loads instantly is worth more than
   one with a typeface, and the system stack is genuinely good now.
