/**
 * Which countries this desk is offered as buttons.
 *
 * Pinned on purpose, which is unusual for a constant. The list is a product
 * decision about where this desk buys, and dropping an entry removes a button
 * without breaking anything else: the field still accepts any ISO code, the
 * publishers still send whatever is stored, and no other test reads it. India
 * was deleted on 24 Sep inside a rewrite of the docblock above it and nothing
 * noticed, which is exactly the shape of change this guards.
 *
 * A failure here is not a bug. It means somebody changed where this desk
 * advertises, and should say so in the same commit.
