   NOTE ON cnc.css: this file deliberately does NOT `@import "cnc.css"`.
   The gated area must be *visually distinct* from the public catalog so
   that a screenshot or a printout is instantly identifiable as
   restricted material, and importing the public sheet would couple the
   two token sets. Everything needed is defined below. If you later want
   the public shell, add `@import "cnc.css";` as the very first line.
