/* FARADAY: site styles

   System
   - Type: Geist for reading and headings, Geist Mono for data (dates, counts, citations,
     breadcrumbs, specs). Syne ExtraBold is the wordmark only. All three are SIL OFL.
   - Structure: one framed column. Hairline rules mark the frame edges and every section
     boundary, with a small cross where they meet. Structural boxes are square; interactive
     controls get a small radius; panels get a slightly larger one.
   - Colour: graphite and pounamu. Pounamu marks links, focus and anything current. Red is
     reserved for urgent help.
   - Dark is the default; [data-theme="light"] switches. */
