 * 3-Post Hero Layout — Frontend Styles

 * All classes use the `tphl-` prefix to ensure complete isolation:
 * - No conflict with theme/plugin CSS
 * - No dependency on WordPress's runtime per-block layout CSS
 * - Plugin renders identically regardless of active theme
 *
 * Extracted and adapted from the source theme's hero section CSS,
 * with every selector renamed to the `tphl-` namespace.
