/* =============================================================================
 * FourcardsAI — precompiled Tailwind (v3 semantics), self-contained, no CDN/build.
 * Contains: (1) Tailwind Preflight base reset, (2) ONLY the utility classes that
 * index.html actually uses (incl. sm/lg/xl responsive + arbitrary values).
 * If you add new Tailwind classes to the HTML later, add the matching rule here
 * (or switch to a real Tailwind build).  MIT-licensed reset, same as the CDN had.
