+## The hero video
+
+The home hero plays `public/video/hero-plant.mp4` / `.webm` behind the headline, over the
+`plant-at-dusk.jpg` still. The still is the video's own first frame, so it carries the hero until
+the video is ready and stays put for anyone who never gets one.
+
+The video is only fetched when it will be seen: not under `prefers-reduced-motion`, not on
+`saveData`, and not below 48rem, where a 21:9 frame would be cropped to a sliver for the most
+expensive bytes. The sources are attached by script rather than in the markup, so nothing is
+requested otherwise. A blocked autoplay also just leaves the still in place.
+
+The source clip was generated with Magnific (Kling 2.5, 10 s, from the hero still as its start
+frame, https://www.magnific.com/app/creation/5jPaI3qKxe). `scripts/encode-hero-video.sh` turns a
+clip into the looping file: it plays forward, then backward, so the loop point cannot be seen, and
+encodes 1920-wide H.264 and VP9. A 20-second loop lands at 862 KB and 472 KB. To replace it:
+
+```sh
+FFMPEG=/path/to/ffmpeg ./scripts/encode-hero-video.sh source.mp4 public/video/hero-plant 1920
+```
+
+Keep the first frame of any replacement equal to `plant-at-dusk.jpg`, or replace both together.
