/*
 * sonn — the product site.
 *
 * The identity is not invented here. It is the one the server already draws on `/`
 * (`public/index.html`): near-black ground, a single green accent, one hairline as the
 * structural device, Hanken Grotesk for what things *are* and JetBrains Mono — engraved,
 * uppercase, tracked out — for what things are *called*. This file carries that to a page
 * that has to hold ten screens instead of two links, so it adds scale, rhythm, light and
 * motion — and nothing that isn't already in the product's vocabulary. The logo is a
 * roofline over a level meter; every animated element on this page is one of those two
 * things at a different size.
 *
 * No build step, no dependency, no request that leaves the box: the two fonts sit next to
 * this file, the icons are inline SVG, and everything else is a rule below.
