 * Every colour here is a token from @musito/brand (loaded by assets/tokens.css,
 * generated at build time) - no hex value is written in this file, because the
 * brand package is the single source of truth and a colour that does not exist
 * there is a change to the brand repo, not a local addition.
 *
 * Strata is flat: no gradients, no glows, no shadows. Depth comes from bands of
 * flat colour, in roughly the brand's ratio - deep teal for the two bands that
 * speak, chalk for the ones that explain, sand as the only accent on top of
 * them, and mint appearing solely inside the mark.
