/*
 * Styx. One idea: the horizon, and the river on it. Above is day, below is night. Long lives above,
 * short lives below, the pool is the line — the Styx between two worlds, drawn as a sodium river.
 * All UI is one white layer drawn in difference mode, so text, charts and the accent invert as they cross:
 *   --fg     -> near-black above, pale grey below
 *   --signal -> cobalt above (#1E2BD6), sodium below (#BAAF07)
 *   the river (sodium in the world layer) turns cobalt wherever UI ink crosses it, as in the logo and banner
 *   #000     -> a hole that shows the world: use it to mask what scrolls under
 * Brand: inverse-rh/brand/README.md (mark, banner, wordmark: Anybody 900 at width 150).
