- Add -pix_fmt yuv420p to multi_res_output.py libx264 path so browsers can decode CPU-encoded segments (was producing yuv444p / High 4:4:4). - Switch silent auth check and coop fragment middlewares from opt-out blocklists to opt-in: only run for GET requests with Accept: text/html. Prevents unnecessary nav-tree/auth-menu HTTP calls on every HLS segment, IPFS proxy, and API request. - Add opaque grant token verification to L1/L2 dependencies. - Migrate client CLI to device authorization flow.
