/* ============================================================
   STYLE ISOLATION
   The widget must keep its own look on any host page. Host CSS —
   element selectors (h1-h6, p, a, ul, input, …) and class rules
   like `.center { text-align:center }` — must not leak into the
   widget UI. We therefore normalise typography and layout inside
   .pdd-widget and inside every widget overlay that mounts on
   <body>. Widget-internal classes below re-declare their own
   styles and win thanks to higher specificity / later order.
