// dvxPrefs.h — INI-based preferences system
//
// Loads a configuration file at startup and provides typed accessors
// with caller-supplied defaults. The INI file is read-only at runtime;
// values are queried by section + key. If the file is missing or a key
// is absent, the default is returned silently.
//
// The underlying parser is rxi/ini (thirdparty/ini/src).
