 *  QR + vCard  MODULE   (v10 — gold card, one‑shot PNG cache, no proxy)
 *  ----------------------------------------------------------------------
 *  • FIRST build only:   calls the *public* QR‑server API directly,
 *      saves  /social/<slug>/qr.png  (no proxy PHP include, no echo).
 *  • Subsequent builds:  read & serve that PNG; browser never sees a
 *      broken link because the file is written before HTML is flushed.
 *  • No TTL logic – any future full‑site rebuild will regenerate the
 *      PNG automatically if it is missing.
