// Minimal local simulator for testing SAN01 replacement only.
// Local simulator that serves the exported build and replaces CGI placeholders from mocks/.
// - Serves the exported "out" folder.
// - For text files (.html, .js, .json, .css, .txt) replaces <%=SAN01%> -> "ismail" on the fly.
// - Replaces placeholders like <%=SAV00%>, <%=SAN01%>, DANxx/DASxx etc. using mocks/device-cgi-simulator/**.
// - Supports mapping /CPL?/path to /path in the export.
