/* ==========================================================================
   Beauty Salon Finder — Design System
   Palette is fixed by the brand brief. Typography is pulled directly from
   the logo itself: a high-contrast serif for "Beauty" (headlines here use
   Playfair Display) paired with a clean wide-tracked sans for "SALON
   FINDER" (DM Sans, used for UI/body + the uppercase label treatment).
   The rose-magenta swoosh under "Beauty" in the logo becomes this site's
   signature: a short curved accent rule under section headings.
