Changed
- The HDMI panel is a grid of ports rather than a list. Four near-identical rows meant reading all of them to find the one carrying signal. As tiles, the live port is the only one with words on it: an empty port is its number on a dashed outline, a port with a device attached but nothing playing reads
Idle, and the port in use carries the label and the link detail.
Behaviour is unchanged — the same /api/hdmi, including its refusal to pair signal to an input when more than one port is live.
