/* The kit: the design system every tool shares (Spin n’ Speak, Teamspin, Classboard).
   Forest ink on sky and paper, fox orange for actions, six bright accents. Rounded type (Nunito), stickers for big titles,
   pills for buttons and menus, soft cards. The fonts are served from this site (fonts/, SIL Open Font License),
   so no tool makes requests elsewhere. Each tool adds its own stylesheet after this one. */
