/*
 * Statisfy website.
 *
 * Tokens follow the app (src/theme/themes.ts, dark palette): Manrope, a
 * graphite near-black, and one green that means "the primary thing". The green
 * is the app's #1DDB6E, and text on it is #062814, because white on that green
 * reaches only 2.6:1.
 *
 * The one loud element is the hero's diagonal bars, lifted from the app icon.
 * Everything else stays quiet: hairlines instead of cards, left-aligned text,
 * one typeface. If you add a section, resist giving it a background of its own.
