/* ============ HOMEPAGE INTRO VIDEO ============
   Sits between the partner logos and "Our Products", just the video.
   All the interest is in how the video itself moves (index.html drives its
   transform with a spring, so it lags the scroll a touch and overshoots):
   - scrolling in, it stands up from lying back, like a laptop lid opening,
     rising and growing, then settles with a small bounce;
   - scrolling out at the top, it tips forward and away;
   - on hover it leans slightly toward the cursor, while a
     "Watch the introduction" pill follows the cursor. Clicking anywhere on
     the video plays the full version with sound. */
