A clear handoff.

Clear Passage is the Secret Handoff identity. Two people meet within an H, with a deliberate gap between them.

Color with a purpose.

Cobalt marks actions. Ink carries the message. Light and dark surfaces give the content room. Reserve red for errors and destructive actions.

Typography

Instrument Sans for headings and interface text. IBM Plex Mono for commands, code, and technical labels. Fonts are served locally with their open-source licenses.

Icons

Open geometry on a 24-pixel grid with 1.75-pixel strokes. Icons support clear text and never replace a necessary label.

Voice

Plain, specific, and calm. Explain what the user approves and what the tool does. Say “No secrets in the chat,” not “No leaks.” Distinguish a sealed request from a one-time link that reveals its secret to the recipient.
