04 · Typography

Three families, three jobs.

Each family carries a distinct register. Don't mix them — display, body, mono.

Display · Instrument Serif

High-contrast modern serif. The “engraved certificate” type. Used for hero headlines so the brand reads as a notarial document, not another tech startup. Variable weight, italic available. Free via Google Fonts.

Define once. Protect everywhere.

font-display · Instrument Serif
Body · Public Sans

The United States Web Design System body font. Literal civic-infrastructure type. Phosra implements OCSS, an open public-interest standard; pairing with the public-government font is conceptually aligned and visually distinctive. Variable weight 300-900. Free via Google Fonts.

OCSS is the open registry of age-appropriate-design rules that browsers, app stores, routers, and operating systems can implement verbatim. Phosra is its reference implementer.

font-sans · Public Sans
Mono · JetBrains Mono

Honest engineering monotype with the right amount of personality. Used for eyebrows, protocol labels, data, code citations. Free via Google Fonts.

05 · State vocabulary

Five roles, never decorative.

Every status-bearing element picks a role from this five-role vocabulary. The signal green is sacred — only LIVE pulses.

LIVE

Actively notarizing right now. The only role that glows.

--state-live
ATTEST

Sealed / cryptographically attested but not propagating.

--state-attest
QUEUE

Pending action. Approaching deadlines.

--state-queue
STALE

Superseded, expired, off. No glow.

--state-stale
DENY

Explicit block. Failed verdict. Hard error.

--state-deny
06 · Usage

Do · Don't.

Do
  • Use the wordmark on dark canvas by default
  • Maintain minimum clear space around the mark equal to the cap height
  • Use signal-400 for the one CTA per fold; let the rest stay quiet
  • Use the bone manifesto card for one warm note per page
  • Use capability glyphs at 16/24/48/64/96px (single stroke at all sizes)
Don't
  • Use emoji anywhere
  • Stretch, skew, or recolor the wordmark or mark
  • Use the signal green for "feature enabled" — only for live, signed events
  • Stack two signature backgrounds (network grid + conic mesh — pick one)
  • Use stock photography or AI-generated imagery of children
07 · Marks

Two marks. One owner each.

Phosra protects its own wordmark and mark.The Phosra wordmark and the standalone mark above are Phosra's trademarks. Use them to refer to Phosra; don't stretch, skew, or recolor them, and don't imply endorsement.

The OCSS conformance mark is OCSS-owned.OCSS is the open standard, owned by no one vendor — Phosra is its reference implementer, not its owner. The “POWERED BY OCSS” and any OCSS conformance mark belong to OCSS and are earned through conformance, not issued by Phosra. See the trademark policy for permitted use of each.
