/* Transeen site.
   StupidMirror's family: one near-black ground, Geist, large type, the product first.
   Transeen's own colours come from its icon: the mint card is the translation, the ivory card
   the original, the tile green the field. The motif is the ⌃⌥2 selection, a hard rectangle:
   page surfaces are square, and only the product's own fragments (marked data-ui) keep
   macOS corners, strokes and shadows. */
