/**
* EDR's load/unload facilities, mapped onto the yards that already represent them.
*
* The codes are historical and don't read like the facility names, so map by code
* and never by label: Indode is `KALITY` ("Gelan Multi Purpose Port (Indode)") and
* Sebeta is `LEGACY_DEST` ("Sebeta"). Creating fresh INDODE/SEBETA yards would
* split data that existing routes and bookings already point at.
*
* Only Indode stores cargo, so it is the only facility with a warehouse — the rest
* move cargo on and off the train, which is why they accrue no storage/demurrage.
*
* Negad is deliberately absent: there are two candidates (`NAGAD` "DCT/SGDT" in
* Djibouti and `NEGAD_FY_BCC` in Ethiopia, currently inactive) and it is not yet
* settled which is the intercity facility.
