/* The blur is baked into the video file, never applied as a CSS `filter`.
   Blurring a playing 24fps video costs a full-viewport gaussian every frame;
   measured on a software-rendered client while scrolling, `filter: blur(14px)`
   on this video ran at 14fps against 75fps for the pre-blurred file.

   Two things that look like fixes and are not:
     - `backdrop-filter` on an overlay — re-blurs whenever the backdrop changes,
       which for a video is every frame. Same cost or worse.
     - blurring a small layer and scaling it up — Chrome rasterises a filtered
       layer at its composited scale, so this measured no better (54 vs 53fps).

   Matching the look needs two things that are easy to get wrong:
     - `filter: blur()` is NOT a true gaussian. The Filter Effects spec defines
       it as three successive box blurs, so ffmpeg `boxblur=r:3` matches the
       browser more closely than `gblur` (scored against a real browser render:
       boxblur 0.0072, gblur 0.0081, single-pass boxblur=r:1 worst at 0.0100).
       Radius comes from the spec: d = floor(sigma * 3*sqrt(2*PI)/4 + 0.5).
     - blur() is measured in VIEWPORT pixels while a baked blur scales with the
       image, so the correct radius depends on window width — hence the two
       encodes in index.html. Getting this wrong is very visible: a file baked
       for a 1600px window is ~2x too blurred on a 3840px one.

   Saturation uses the exact SVG saturate() matrix via colorchannelmixer rather
   than ffmpeg's `eq`, which scales chroma in YUV and drifts from CSS. */
