/*
    Public gift-card balance scanner page.

    The layout is intentionally close to /scan-price so phone users see the
    same interaction pattern: result above camera, short camera window, manual
    fallback always available.

    Activity-log note:
        CSS has no durable behaviour and should not be logged. Server-side
        lookup activity is logged in GiftCardController::lookup().
