/*
  Qbitz site — local version (29 sep). Deep blue-blacks, one page per section.
  Theme: qubits — 0 and 1 at the same time. Labels use ket notation in a mono face
  (|001⟩ proyectos); the page headers draw a field of superposed 0/1 that collapse
  where the pointer "measures". Square corners everywhere (no pills).
