/*
 * Fintech Trust, on the web.
 *
 * The same palette the app uses (Docs/DESIGN_SYSTEM.md) so the site and the
 * product look like one thing: cool off-white page, white cards, deep navy ink,
 * one electric indigo that means "act".
 *
 * No framework and no build step. This is five pages of mostly text — a CSS
 * pipeline would be more machinery than content, and machinery rots. Plain CSS
 * with custom properties does everything needed here and will still work in
 * five years.
