/* Operator: shared styles for the Rough Cut and Ryan Podolsky sites.
   In the vein of Palantir and Theorem, where Ryan worked before film: near-black and paper sections,
   one neutral grotesk (Geist) set large, light and tight, Geist Mono for indices and labels, hairline
   rules, and one band of moving color. The band is a slit-scan of a West Texas dusk, drawn live on a
   canvas by operator.js (lilac to cobalt to night). Named for the camera operator, and for what Ryan was
   at Palantir and Theorem.
   Motion runs regardless of the OS reduce-motion setting, by the site owner's choice. */
