/* styles.css — Tip or Nah?  Vanilla, mobile-first, zero runtime deps.
   Identity: a receipt / "permission slip". Display serif (Fraunces) for the wordmark + headings,
   monospace for money, paper background, rubber-stamp verdicts. Verdict meaning is carried by
   SHAPE (icon) + TEXT + colour, so it survives colour-blindness and platform emoji differences.
   All verdict chips use solid fill + white text → WCAG AA clears comfortably. */
