/* Look Who's Talking — site styles.
 *
 * Hand-written rather than a framework or a CDN: the site is five static pages,
 * so a few hundred bytes of CSS is smaller, faster and has no external runtime
 * dependency. Tailwind's play CDN is documented as development-only and ships a
 * runtime compiler, which is why it was rejected — see specs/Project_Decisions.md.
 *
 * Mobile-first: most visitors arrive from the Play Store listing on a phone.
