"""Enable Kodi's JSON-RPC web server by seeding its guisettings.xml.

mediapi controls Kodi over HTTP JSON-RPC, which requires "Allow remote control
via HTTP" -- a setting normally toggled in Kodi's GUI. This seeds it headlessly.

IMPORTANT: Kodi rewrites guisettings.xml when it exits, so this must run while
Kodi is STOPPED (install.sh handles the stop/seed/start ordering). It merges
into any existing file, so re-running is safe.

Reads the desired values from the environment (with sensible defaults matching
.env.example):
  MEDIAPI_KODI_PORT, MEDIAPI_KODI_USER, MEDIAPI_KODI_PASSWORD

Usage: configure-kodi.py [path/to/guisettings.xml]
       (default: ~/.kodi/userdata/guisettings.xml)
