/**
 * Zibll utility class bridge
 *
 * Single / author / meta markup still uses Zibll utility class names
 * (.flex / .ac / .jsb / .abs-right / .muted-2-color / …). Without these
 * helpers the author bar and meta row collapse into a vertical mess.
 *
 * Keep this file tiny and pure utility — domain styles stay in single-post/*.
