/**************************************************************************
 *  RSS MODULE  (v9 — file‑cache + robust error handling)
 *  ----------------------------------------------------------------------
 *  • First good build:  fetch RSS/JSON → render <ul> → save to
 *                       /ph/<phone>/rss-cache.html   or  /social/<handle>/rss-cache.html
 *  • Later builds:      serve cached HTML (unless older than $ttlSecs)
 *  • If feed is mis‑configured or unreachable we either
 *        – fall back to last good cache,  OR
 *        – show a 1‑line muted error (no empty card)
 *  • Nothing is echoed to the page except valid markup.
 *    Detailed reasons go to the PHP error‑log.
