// Role assignments for the Darkmatter palette.
//
// Ported from Nordic's _colors.scss and kept variable-for-variable compatible,
// so every widget partial compiles unchanged. Where a derivation is inherited
// it is left alone; where Nordic's base was mid-dark and Darkmatter's is
// near-black, a darken() would bottom out at black — those few are noted and
// resolved against a palette step instead.
