/* Appointment Engine design system (2026-09-15).
   One family, DM Sans, at light weights; near-black ink, quiet grays, a
   single blue accent, hairline borders, pill buttons. Used by every page
   under /appointments and by the homeowner funnel templates. Bump the ?v=
   on every <link> in the same commit as any edit here (netlify.toml caches
   /css/* for a year). */
