Announcement Bar · ecomcn

The thin inverted ink bar above everything — free-shipping thresholds, sale windows, drops — with a brand dot between messages. Static, or a marquee at 26s a loop that holds still under the pointer or focus and has a pause button; under reduced motion the marquee doesn't run. Dismissing folds it away and is remembered per version, so it stays gone across routes and visits until the announcement changes; pass `dismissed` from a cookie to skip it on the server.
