/* ==========================================================================
   Hack The Cure — design system, second edition
   Type:    Besley (display, a Clarendon) + Atkinson Hyperlegible Next (text)
            + Atkinson Hyperlegible Mono (labels and numbers).
   Palette: aubergine ink on bone paper, coral from the logo as the accent.
            The six track colours run amber to fuchsia and are only used to identify a track.
   Surface: one sheet of paper. Sections are separated by ink rules, not by
            boxes, so nothing here is a card inside a container inside a band.
