   Idea: a marked-up log printout. Cool paper, ink, and a highlighter that only ever touches the line that explains things.
   Red is reserved for symptoms. Yellow is reserved for causes. Nothing else gets a colour.
   Type: Darker Grotesque for headlines (tight, heavy, a little odd), Atkinson Hyperlegible Next for reading
   (drawn for low-vision readers, which suits someone who builds tools for kids who struggle with text), and its Mono sibling for evidence. */
