/* Prima Mountain Cabin — primabnb.com
   Design language deliberately mirrors bluestoneluxuryproperties.com so the two
   Front Royal properties read as siblings: Raleway 500 display, Inter Tight for
   body and utility, #284D63 accent, full-bleed photo sections, square buttons.

   The one element that is Prima's own is the horizon rule (.rule) — a hairline
   standing in for the ridge line the whole house faces. It is the only
   ornament; everything else stays quiet. */
