/* Trading Journal by Kiawak: landing, legal, sign-in and account pages, plus the
   thin bar above the app. Design "Nachtschicht am Desk": graphite trading desk
   (dark by default), paper white light theme, Kiawak blue #2f54eb only for the
   main action and the mark's diamond, wins teal / losses vermillion (Okabe-Ito
   family, readable with colour blindness; signs and shapes carry the meaning too).
   Type: Geist (text and headings), JetBrains Mono (figures). The same tokens feed
   the journal UI through client/theme.css. */
