A geometric sans built from squared, superellipse-like forms with consistently rounded corners and uniform stroke weight. Curves tend to resolve into rounded-rectangle geometry, giving bowls and counters a compact, engineered feel while keeping apertures fairly open for clarity. Terminals are mostly flat and crisp, with occasional softened joins that reinforce the systematic, modular construction. Overall spacing and rhythm read as even and controlled, with a clear, sturdy presence in both uppercase and lowercase and similarly constructed lining numerals.

Well-suited for user interfaces, product labeling, and wayfinding where a clean, engineered look is desired. The open counters and consistent stroke weight help it stay legible in short bursts of text, and the squared-round numerals make it a solid choice for dashboards, settings screens, and data-forward layouts.

The tone is contemporary and technical, with a calm, matter-of-fact voice. Its rounded-square geometry adds a friendly softness to an otherwise industrial, interface-oriented character, balancing approachability with precision.

The design appears intended to deliver a modern geometric sans with a distinct rounded-rectangle skeleton—recognizable, systematic, and easy to deploy in contemporary digital and industrial design contexts.

The uppercase set feels sturdy and architectural, while the lowercase maintains the same squared-round logic for strong family coherence. The numerals share the same straight-to-rounded transitions, supporting a consistent visual texture in data-heavy settings.
