/*
 * Gitit — Billing, pricing, and legal-page styles.
 *
 * Covers the teacher-facing /billing page, the public /pricing page, and the
 * shared layout for the public /legal/terms and /legal/refunds pages. Existing
 * legal pages (privacy, ferpa) keep their own inline styles for now — when
 * they're touched next, fold them into `.legal-page` selectors here.
