/*
 * Genie's palette is the family's.
 *
 * `unity-theme.css` — linked from index.html, and a byte-identical copy of the
 * canonical theme — owns the colours; Genie is a CodeOps console, so it wears the
 * **operations** scheme. The names below are the ones this stylesheet's rules have
 * always used, aliased onto the theme's tokens, which is what let the console gain
 * light mode without every rule in this file being rewritten.
 *
 * `--ok` is deliberately *not* listed here. The theme already defines it, and
 * `--ok: var(--ok)` is a cycle: the custom property would be invalid at
 * computed-value time and take the colour down with it.
