Typography
Typography reinforces the Prelude Security brand voice and improves readability across all touchpoints. The type system uses two brand fonts for marketing and communications, paired with two UI fonts for product and technical contexts.
Brand Fonts
Section titled “Brand Fonts”Argent CF is our serif display typeface used for headlines and hero statements. Its refined letterforms convey authority and precision. Articulat CF is our sans-serif workhorse for body copy, subheads, and general brand communications.
Both are available through Adobe Typekit and are loaded automatically on all Prelude properties.

UI Fonts
Section titled “UI Fonts”IBM Plex Sans is used for product interfaces, documentation, and UI labels. IBM Plex Mono is used for code, terminal output, and technical data. Together they ensure clear distinction between narrative content and machine-readable information.
