/*
  THESIS: A large-format exhibition index, not a dashboard of demo cards.
  OWN-WORLD: Carbon walls, exhibition paper, acid marker, alternating project plates.
  STORY: Ten current works lead; authorship and craft are legible; older work waits in one archive drawer.
  FIRST VIEWPORT: A poster-sized “10”, the promise “Zehn Websites. Kein Template.” and a collection ledger.
  FORM: Editorial exhibition catalogue; each project receives a subject-specific CSS specimen.
