Styling

All styling is inline within index.html using CSS custom properties:

Variable	Value	Usage
--red	Red	Primary accent
--black	Near-black	Text
--grey-bg	Light grey	Page background
--off-white	Off-white	Card backgrounds
--slab	Alfa Slab One	Display headings
--sans	Inter	Body text
--mono	IBM Plex Mono	Code and technical text

The design uses a light colour scheme with a bold slab-serif display font for an editorial book-promotion aesthetic.

Build and Serve

Single-stage Dockerfile:

1. nginx 1.28.2 Alpine copies public/ directly into the web root
2. sed replaces {{COMMIT_SHA}} in index.html at Docker build time
3. Runs as non-root on port 8080
