Clicking a Nisse opens a top-left panel showing name, AI status,
energy bar, active job, job priority buttons, and a live work log
(last 10 of 20 runtime-only entries). Closes via ESC, ✕, or clicking
another Nisse. Dynamic parts (status/energy/job/log) refresh each
frame without rebuilding the full group.
