   Neutralize WP core responsive-embed aspect-ratio spacing.
   Core uses a ::before with padding-top to reserve space for the

   padding-bottom for the 16:9 ratio, so the core ::before creates
   unwanted whitespace. Disable it in both poster AND playing states
   — the poster div handles aspect ratio in all states since the
   iframe is placed inside it, not directly in the wrapper.
