Colophon

Last updated 2026-04-13

A colophon is where a book tells you what it's made of. This is ours.

Typography

The serif is Fraunces, served via next/font from Google Fonts. The sans is Inter, served the same way. Fraunces was chosen for its contemporary warmth at display sizes; Inter for its quiet neutrality in the body, where it gets out of the way and lets the sentences do the work.

Design

The design language is hairline borders, no drop shadows, and color driven entirely by four CSS custom properties: --bg, --fg, --accent, and --muted, which switch values on a dark class. Nothing else touches color.

Behind the type is an ambient field: a canvas-based composition of three warm radial gradients that drift gently with the cursor, breathe on an eight-second cycle, and shift with scroll. A small practiced answer to the book's argument that systems should reach the reader without demanding the reader's constant attention first.

Engineering

Next.js 15 on the App Router, React 19, Tailwind CSS v4, and TypeScript. Deployed on Vercel. Structured data is provided via JSON-LD. SEO includes a robots.txt that explicitly welcomes LLM crawlers, and an llms.txt file for generative-engine readers.

Accessibility

The site respects prefers-reduced-motion, uses semantic landmarks, honors focus-visible rings, and relies on native <details> disclosure for the FAQ. No custom accordions, no trapped focus.
