/**
 * Brøns Konfigurator Lite - frontend.
 * Farverne --bkl-accent og --bkl-dark sættes fra indstillingerne.

/*
 * Farverne er målt på jcb.com: gul #FCB026, varm mørk #262626 og lys #F2F2F2.
 * JCB bruger ikke sort, men en varm mørkegrå - det er den, der gør at deres
 * flader ser ud som maskiner og ikke som en hjemmeside. Radius er 4px, og
 * knaptekst er almindelig, ikke versaler.
 *
 * Skriften er Roboto, fordi JCBEuro er licenseret og jcb.dk allerede henter
 * Roboto. Fallback-kæden efterligner JCB's egen: humanistisk sans.
