Summary
Defers the Vimeo iframe on the homepage until the user clicks the play button.
Problem
The Vimeo embed loads ~500 KB of third-party JS/CSS on every page visit, even when the user never watches the video. Lighthouse flags this as render-blocking resources and third-party code that limits performance.
Solution
Replace the always-rendered
<iframe>with a click-to-play pattern:background-imageon.video-container) with an SVG play button overlay<iframe>withautoplay=1so playback starts immediatelyNo visual change before interaction. Cookie consent / DNT logic is preserved.
Lighthouse impact
Closes #217
