/* ── glass spheres — switched off ──────────────────────────────────────
   These worked because there was something dark behind them to bend: a
   backdrop-filter that refracts and desaturates, plus a radial highlight so
   the sphere had a light source rather than looking like a grey circle. On
   paper there is nothing to bend and the highlight has nothing to sit on, so
   the same CSS renders as four grey circles - which is what the last sentence
   of that explanation was warning about.

   Steep also has no abstract graphics at all; its imagery is product
   surfaces. So .orbs is display:none below rather than deleted - the markup
   is five empty divs, and bringing the dark page back is one line. */
