   SWITCHBACK interior pages. Each page lives at its own hour of the day:
   Projects = THE SURVEY (midday) · About = THE TRIP LOG (golden hour)
   Blog = THE LOGBOOK (dusk) · 404 = OFF TRAIL (night)
   Articles = field-journal entries on paper.
   The homepage has its own sheet (home.css); shared voice: Geist landscape,
   Geist Mono instrument, blaze-orange trail.
