/* ==========================================================================
   Boston Dental HQ, site layer v2 (loads after each page's inline <style>).
   Same identity as today: charcoal blue, serif headings (Fraunces), Poppins body, the
   Kutchenhaus-style desktop header and the Rise-style phone header. What changes is craft:
   spacing and rhythm, type scale, image treatment, depth, controls, states, motion.
   Governing idea: "a calm, well-lit reception desk": quiet surfaces, one confident headline,
   controls that answer the touch, motion that says "arrived" and never "look at me".
