/**
 * SHORT.bid design system.
 *
 * Replaces four overlapping stylesheets that were all loaded at once:
 * style.min.css (604 KB, the purchased template), sb-admin-2.css (224 KB),
 * app.css (288 KB, unreferenced) and the Tailwind play CDN, which compiles in
 * the browser on every page view.
 *
 * Values follow Apple's own: #1d1d1f ink, #f5f5f7 alternate ground, a single
 * #0071e3 accent, 980px pill controls. The font stack is the platform's, which
 * resolves to SF Pro on Apple hardware and costs no webfont download - the
 * right trade for a service whose product is speed.
