teaser v9 final: music reworked for the tight cut (drives from frame 0, an accent on every cut, tension in the pile and the rejection, a short drop into the request, layers building through the montage, the stop on Submit, the resolve on Waiting for review, a confident end under the card fading over the last 1 s; -16 LUFS, true peak <= -1.5 dBTP); 1920x1080 master, web version and posters from the end card; site teaser and poster (cache key v=5), README poster
