/* Mineral Saga. The ground is the black bench the specimens are photographed
   on; the ink is paper-white; the one accent is the green that willemite
   answers with under a shortwave lamp. The wordmark's slab is echoed by
   Alfa Slab One; the running text is a book serif; specimen numbers are
   mono, like the label roll. Committed to one look: everything below paints
   its own colour, nothing borrows the host's. */
