/* Ciudades de España, edificio a edificio. Two themes: noche (default), a navy dusk with an albero-gold accent, and
   día, warm sand with terracotta. Panels are frosted glass over the city; Fraunces for names and years, Manrope for
   everything else. The 3D colours that go with each theme live in app.js (THEMES). */
