A short-term rental marketplace exports its `listings`, one row per listing with a host and a bed count, and a single host can own several. We're publishing host standings, where a host's standing is the total beds across all of their listings. Produce the standings, biggest hosts first.
Summary
Count every bed under a name. The largest holdings rise first.
