Replace the spheres with AdobeStock_1457104053 — abstract flowing wave/particle
field on near-white (blends into paper). Optimized 60MB->1.1MB H.264 (1280x720,
crf 25, faststart). Dropped the webm: VP9 came out larger than H.264 for this
thin-line content, and H.264 plays everywhere, so a single mp4 source is smaller
and universal.

Transcoded the VP9 webm to H.264 mp4 (~220KB) and add it as a second <source>
after the webm — modern browsers take the smaller VP9, pre-2021 Safari/iOS fall
back to mp4. JS appends both sources before load().
