Viewer

Generate a vf viewer URL that is reachable from the current browser and bounded to the configured channel capacity. Viewer channel indexes are zero-based even though media-source slots are one-based.

📄️Build a browser-reachable vf viewer URL

Constructs the vf HTTPS viewer URL on port `8081` using the current request host, selected color mode, and zero-based channel selection. When `src` is omitted, all channels within the resolved capacity are included; supplied indexes that are invalid or exceed an SDK port-publication limit are discarded. The response also explains whether capacity came from a DevKit, the SDK port map, or the legacy 80-channel fallback.
