/**
 * CertFlow Helper - product-page date picker (.cfh-pdc).
 *
 * Port of the hub's public-product-calendar.css with every cf-pdc token renamed to
 * cfh-pdc (class names AND custom properties), so the Helper can never collide with
 * CertFlow's own styles if both plugins end up on one site.
 *
 * Show/hide uses the [hidden] attribute and class toggles, never inline display:none -
 * an inline style would lose to the flex/grid rules below.
