 * Light by default, on the console's own light tokens — someone who installs
 * this should recognise the product they just saw. The hero is the exception:
 * it keeps the dark stack, the starfield and the mint accent, because one
 * dramatic moment at the top is worth more than a uniformly dark page.
 *
 * Dark is done by re-declaring the tokens inside .hero, so every component
 * below works in both without knowing which it's in.
