 * setCustomerAttribute, selectedProducts, getSelectedCampaign,
 * getPaywallActionEventData, setOpenHeaderIds, setPurchase, etc.

 *  - Lit ReactiveController integration (host.requestUpdate on state change)
 *  - Dynamic state getters that read from the DOM (tvQuality, viewport dims)
 *  - Type-safe static method overrides returning PaywallContextProvider
