A hairline monospaced slab serif with square, unbracketed terminals and a crisp, linear drawing style. Strokes are consistently thin with little visible modulation, giving the forms a clean, engineered rhythm. The serifs read as small, flat slabs that cap stems and arms without curved transitions, while counters stay open and evenly proportioned. Spacing is disciplined and uniform, producing an orderly grid-like texture in both uppercase and lowercase.
Best suited to short to medium text where a crisp monospaced voice is desirable—such as code blocks, tabular readouts, UI labels, and technical documentation headings. It can also work for editorial pull quotes or branding that wants an understated, precision-led aesthetic, especially at larger sizes where the hairline detail holds up.
The overall tone is quiet, precise, and modern, with a slightly archival, typewriter-adjacent restraint. Its extreme lightness and measured proportions feel refined and airy, lending a calm, analytical mood rather than warmth or exuberance.
The design appears intended to blend monospaced regularity with slab-serif cues, creating a rational, contemporary toolface that remains elegant and unobtrusive. Its thin strokes and square serif finishing suggest an aim toward clarity, alignment-friendly typography, and a distinctly measured visual cadence.
Round forms (like O/0) appear nearly circular and delicate, and the thin horizontals give the design a noticeably luminous color on the page. Numerals and punctuation maintain the same pared-back construction, reinforcing the font’s consistent, systematic voice.
