How this site is made.

Type

Display and headings are set in STIX Two Text, a face designed for scientific and mathematical publishing — the Σ in the wordmark is native to it, not a decorated glyph. Prose is Instrument Sans; eyebrows, indices, and the fine print are Spline Sans Mono. All three are served from this domain. No type — or anything else — is loaded from a third party.

The marks

The emblem — a lion and trident rising from a wave, forming an S-curve — predates this site and carries on unchanged. The Summation Mark on the front page is typeset, not drawn: a Σ with lower bound i = human, which is the house’s thesis in three characters of mathematics.

Stack

Static-first pages built with Astro and hand-written CSS on a small token system; the Library and correspondence are served from a Postgres database at the edge. The whole site ships less JavaScript than most sites’ cookie banners — which is fitting, because it has no cookie banner: there are no cookies, no analytics, and no trackers to consent to.

Left out, deliberately

Stock photography. AI-generated imagery of people. Newsletter pop-ups. Engagement metrics. Anything that would need a consent banner. The site is typeset, not “designed” — if the type system fails, the site fails, and that is the point.
