/**
* Malawi (MW) address configuration.
*
* Order: house/plot NUMBER first, then street name + trailing English type
* ("10 Glyn Jones Road") — GB-style number-first, suffix type. English is
* an official language. Lilongwe/Blantyre are laid out in numbered
* "Areas" ("Area 47", "Area 3"), which sit where a street would and, with
* no street slot of their own, land in `street` (untyped) — lossless.
* Type: trailing English suffix (Road, Avenue, Street, Drive, ...) or null.
* Locality: a township / area may sit between the street and the city; the comma
* chain is kept together and the leading area(s) dropped in postNormalize.
* Postcode: NONE. Malawi has never operated a postal-code system (Malawi Posts
* Corporation; UPU S42 MW template has no postcode field). Never-match
* sentinel; the after-city grammar supplies "..., City".
* Region: the 3 regions / 28 districts are essentially never written on mail; no
* `state` is modelled (county slot disabled so it cannot eat the city).
* PO Box / Private Bag: DOMINANT. "P.O. Box 30390, Lilongwe",
* "Private Bag 1, Zomba".
*
* Sources: Malawi Posts Corporation (MPC); UPU S42 MW template; Smarty /
* PostGrid MW guides (postcodes not used). See research-mw.md.
