/* Shared visual language for every page under site/.
 *
 * Extracted from index.html when the transients tool became a second page:
 * two copies of a token set drift, and a tool that does not look like the
 * project it belongs to reads as someone else's.
 *
 * Three theme states, not two. An explicit choice stamps data-theme on the
 * root; the default "system" setting stamps nothing, so only
 * prefers-color-scheme separates light from dark there. Every colour is
 * declared on bare :root first and only redefined in the two blocks below.
