 * Masthead video background
 * -------------------------
 * The masthead photo (bg-masthead.jpg) is replaced by a looping video
 * (cloud_loop.mp4 is a "boomerang": the clip forwards then reversed, so it
 * loops perfectly with no break). The photo is kept as the <video poster> so it
 * shows instantly while the video loads and as a fallback if the browser can't
 * play it. The dark gradient that used to live on .masthead's background is
 * moved to .masthead-overlay so it sits ON TOP of the video and keeps the
 * headline readable.

 * colour (#f8f9fa = Bootstrap's .bg-light) so the dark blends smoothly into the
 * white instead. The top stays black to keep the heading text readable and to
 * meet the dark bottom of the masthead seamlessly.
