/* oaica.com — the site design system.
 *
 * One stylesheet for every page, so "the site" is one thing and not five
 * documents that happen to share a hostname. The conversion architecture is
 * borrowed from shipfa.st: a scarcity badge above the fold, a cost-of-doing-
 * it-yourself ledger, a comparison, pricing with the discount struck through,
 * an FAQ that answers the objections, and a closing CTA. The skin is ours —
 * white, near-black, one highlighter accent — because a dark hero is a
 * fashion, and this page sells a tool that runs in a terminal.
 *
 * No webfonts. Loading one from a third-party CDN hands every visitor's IP to
 * somebody else before they have agreed to anything (LG München I 3 O 17493/20),
 * and the system stack is what the app itself renders in anyway.
