How they work together

A boutique litigation firm working federal cases in the Southern District of New York. No junior associates, no marketing team, no billboard on the FDR. Just three partners and a case-selection philosophy that starts with the word no.

03Inter minimum weight is 500. No 300 body copy anywhere.

04JetBrains Mono is for eyebrows, tags, numbers, and code. Never headlines.

05Ink is oklch(16% 0.02 60). Gold is oklch(60% 0.12 65). Never black on white. Never gray on gray.
