/* Plumbing Pros Cave Creek - main.css
   Design language carried from the supplied Cave Creek template:
   charcoal/oxide/mustard desert palette, Arvo slab display over Hind body,
   the repeating stripe rule, the two-line call button, bordered bone cards.
   Component classes are namespaced; the template's short generic names
   (.mk .cb .tk .tr .eb .m .s .est .ins) were renamed to avoid the
   class-collision failure mode. */
