   SIOLFUR — siolfur.in
   "Liquid mercury": chromatic silver on near-black, with an aurora of cyan →
   violet → rose held at the edges. Deliberately distinct from geo.siolfur.in,
   which stays near-monochrome; the apex reads as the parent brand.

   Every motion effect in here is switched off under prefers-reduced-motion.
   The page must be fully legible and usable with all of it gone.
