/* ============================================================
   Bright Smile Dental — Design Tokens
   Palette: mint-white bg, deep pine ink, teal accent, warm amber CTA
   Display: Fraunces (warm serif, boutique-clinic feel)
   Body: Public Sans (clean, legible, trustworthy)
   Labels: Space Grotesk (clinical precision, eyebrows/data)
   Signature motif: the "smile arc" — a soft upward curve used as a
   recurring section divider and card underline, standing in for the
   literal smile without resorting to tooth iconography everywhere.
