+// A clip that plays by itself in the video pager has no poster: every
+// poster there is comes 480px wide and from some moment of the clip, so it
+// showed soft for a beat and the clip's first frame replaced it — a flash
+// on every flick. The slide is the pager's black until the player has its
+// first frame. On a connection to be careful with (Data Saver), where a
+// clip may never load, the poster stays.
+// Run: bun tools/pager-no-poster-test.js
