/* data05 public site, in the 05 family look shared with use05.dev. Workstation: matte black, light grey plastic,
   white paper, blue links. Everything above the "data05 pass" at the bottom is use05.dev's stylesheet, unchanged, so
   the two sites stay one family; data05's own sign (a square blue cell where use05 has a round red dot) is set there.
   Red still means what needs a person. Display and body: Archivo. Code and labels: IBM Plex Mono. Self-hosted (fonts/). */
