# Sonar brand assets

Everything here is production ready. Two sanctioned options.

## Option 2A, grey and navy
Graphite #4A5568 mark on white, navy ink. Use for documents, invoices, chart-heavy decks, letterhead, email signatures, and single-colour print.

## Option 2B, aurora
Violet to cyan gradient from the landing hero. Use for marketing surfaces, social covers, app icons, and campaign posts.

Never mix the two on one artefact.

## Hard rules
Minimum mark size is 24px. Clearspace equals the outer ring radius.
Type is Inter and JetBrains Mono, nothing else.
Numbers are always mono with tabular figures.
Never recolour the sweep outside the brand hues.
Never place the cyan mark on a mid-tone background. Use navy or reversed mono.

Prove the edge. Publish it live.
