/*
 * Academia MG — shared primitives.
 *
 * Only genuinely shared things live here. A component earns its place on its
 * SECOND use, never its first.
 *
 * Type note: Inter tops out at 600. The scale is therefore built on SIZE and
 * TRACKING rather than weight — large type at 500/600 with tight negative
 * tracking reads as editorial; heavy weights read as a dashboard.
 *
 * Depends on tokens.css.
