+ * MMDVM modem log download.
+ *
+ * Sends today's /var/log/pi-star/MMDVM-YYYY-MM-DD.log (or the
+ * dstarrepeater equivalent) as a download. Picks the right log
+ * filename based on which mode marker exists in /etc/. Streams the
+ * file in 8 KiB chunks, with a User-Agent sniff to translate \n to
+ * \r\n for Windows clients.
+ *
+ * NOTE for the security pass: no setSecurityHeaders() call (binary
+ * download), and no auth check beyond the PHP_SELF guard.
