 * styles.css grew several palettes deep (kindergarten pink, tulip, ocean)
 * before the classroom came back to matcha. Rather than rename every
 * selector, each of those old token names is aliased onto a role from
 * brand-tokens.css. Nothing here should hold a raw colour: if you need a
 * new value, add a role to brand-tokens.css first.
 *
 * The matcha and clay names are NOT re-declared here. They are the raw
 * palette in brand-tokens.css, and aliasing them back onto the roles that
 * reference them would make a custom-property cycle and void both.
