/* ============================================================
   PICAZO ARTE Y PINTURA — Site Styles
   Design concept: an art book / gallery catalog, not a tech
   product. Warm paper tones, one deep textured room, an
   expressive serif for titles, generous editorial whitespace,
   and a museum-wall gallery instead of a uniform card grid.
