/*
 * KTDB.NET — Frontend Redesign
 * Modern layout system for the existing GeneratePress-based theme.
 *
 * IMPORTANT: no global element reset (no Tailwind-style preflight) is
 * applied here on purpose. Several bundled plugins (kitu-khoang-trong,
 * ktdb-chunguoc, kituiam, ...) print raw <button>/<input>/<textarea>
 * markup straight into post content and rely on either their own CSS or
 * sane browser defaults. Resetting those tags globally would silently
 * break their UI even though we never touched their code.
