1/**
2 * Betting consent gate (FTDEV-71). Dutch edition only.
3 *
4 * Azerion's Dutch CMP design asks the visitor's age with two buttons, "Akkoord, ouder dan 24" and
5 * "Akkoord, jonger dan 24". The younger one withholds custom purpose c1 ("Betting toegestaan"),
6 * because Dutch gambling rules forbid aiming gambling advertising at under-24s.
7 *
8 * The OneCasino odds strip is gambling advertising: affiliate links plus a bookmaker logo. Blocking
9 * its impression pixel is not enough, the markup itself may not be shown. It is therefore hidden by
10 * CSS from the start and only revealed here, once c1 consent is actually present.
11 *
12 * Fails closed on purpose: no CMP, no answer yet, or a refused purpose all leave the strip hidden.
