/*
 * The front page — the pinboard.
 *
 * Uses the tokens and components defined in site.css; nothing here redefines a
 * colour, a radius or a shadow. The documents are a notebook, so they stay calm
 * and linear. This page is the wall the notes are pinned to, so it is allowed to
 * tilt things, overlap them and stick tape on them.
 *
 * One deliberate exception to the paper aesthetic: the two terminal blocks stay
 * dark and literal. Everything else here is an illustration of the product, but
 * those are machine output — the git log especially, which is what
 * `npm run demo:provenance` genuinely prints. Drawing real output on a sticky
 * note would make the one verifiable thing on the page look staged, so it keeps
 * the screen it came off.
