 * AppConfig
 * ---------
 * Minimal INI-style config file reader.
 * Supports [sections], key = value pairs, and # comments.
 *
 * Keys are accessed as "section.key", e.g. "ui.font_path".
 * Missing keys return a provided default value.
 *
 * The config file is searched in this order:
 *   1. Next to the executable:  <exeDir>/assets/config.ini
 *   2. Current working dir:     assets/config.ini
