/**
 * build.marlyg.me
 *
 * The marlyg.me / portal.marlyg.me design system, verbatim. The token names
 * and values below are the ones those two sites ship, so this reads as the
 * same product rather than a tool that happens to be linked from it.
 *
 * Light only, because neither of the other two has a dark theme. One family,
 * Stack Sans Text, with weight carrying the hierarchy — mono appears in
 * exactly one place, the stream, where the content really is code.
