 * launcher.css — styling for the course landing page.

 * Deliberately shares the milestone design tokens so the launcher reads as the front
 * panel of the same machine. It is standalone (the milestones must not depend on it,
 * and it must not depend on them) but the palette is copied verbatim from
 * M01-first-beat/css/base.css.
