/**
 * Webinar banner styles — split into two eras:
 *
 *   v3 (main banner) — 6 self-contained HTML designs, each with its own
 *   fonts and inline CSS, served in a same-origin iframe. This stylesheet
 *   only supplies the OUTER wrapper (.bna-webinar-v3-wrap) and iframe
 *   sizing — nothing that could leak into the banner's own styles.
 *
 *   v2 (sidebar) — the 4 sidebar variants (`webinar_s1`..`webinar_s4`)
 *   still use the ticket-style receipt below, layered on
 *   `.bna-sponsor-sidebar` from sponsor-sidebar.css.
 *
 * Class map:
 *   .bna-webinar-v3-wrap / .bna-webinar-v3-iframe — v3 iframe container
 *   .bna-ticket-s / .bna-ticket-s__* — sidebar vertical ticket
 *   .bna-ticket / .bna-ticket__* — legacy main ticket (kept for reference /
 *                                   used only if someone reverts to v2 render)
 *   .bna-webinar-tag — legacy "FREE LIVE WEBINAR" tag helper (v2 only)
 *
 * Load order: sponsor-banner.css → sponsor-sidebar.css → webinar-banner.css
