Dark Mode: add a better way of creating opacity variants of colors

Previously, there were things like:

  --some-color: #010203;
  --some-color-opacity-X: rgba(1, 2, 3, X);

Which is a bit inflexible and leads to a bit of redundancy. Instead,
let's use this syntax, which allows minting an arbitrary number of
colors with var() + rgba() syntax:

  --some-color-rgb: 1, 2, 3;
  --some-color: rgb(var(--some-color));
  /* later ... */
  color: rgba(var(--some-color-rgb), X /* any opacity */);
