/**
 * Fatal guard for Better Payment Pro 1.4.3 and older. Holds no schema.
 *
 * The Donors Wall, FAQ and Video schemas and default settings ship with Pro
 * (better-payment-pro/includes/Campaign/ProElementSchemas.php); a free install gets
 * {@see ProElementStubs}. Lite's transitional copy of the schemas was deleted when
 * ProCompatibility::MIN_PRO_VERSION reached 1.4.4.
 *
 * What stays is only what Pro 1.4.3 reads directly: its `BuilderElements` aliases
 * these constants at class-constant time and calls {@see self::default_video_url()},
 * so removing them would fatal every campaign render on a site that updated Lite
 * before Pro. Pro 1.4.4+ reads its own class. Pinned by
 * tests/Unit/ProCouplingContractTest.php; delete this file once no supported site
 * can run Pro 1.4.3.
 *
 * @deprecated Kept only so Better Payment Pro <= 1.4.3 does not fatal.
