How this site is made, and how to read it

Set in Newsreader for body text, with headings in Linux Libertine (Georgia as the fallback — Wikipedia's article-heading stack), and code in IBM Plex Mono. The palette is two colours and paper: aged-paper yellow (#F4EBC8) and manuscript ink-blue (#0E1F4C), nothing else.

The interactive parts are load-bearing, not decoration. Numbers with a dashed underline are draggable — scrub one and every figure and result that depends on it recomputes live. A boxed specimen is a real mechanism running in your browser, not a screenshot. Margin notes come in two kinds: a superscript-numbered note is anchored to a specific point in the text; an unnumbered note with a short rule above it is a positional aside about the passage beside it.

Built with Astro and Solid; the writing is authored in MDX, the maths typeset with KaTeX. The site is open — the source is at github.com/saucam. The long-form pieces go out as the newsletter Read the Source via saucam.substack.com; each is cross-posted with this site as the canonical link.
