Current tab: snapshot KPIs (open, unassigned, avg age) and per-agent
table with open/critical/age columns. No period filter needed.
Performance tab: period-filtered KPI (resolved) with segment control
(30/90/180/365d) and per-agent table sorted by resolved count.
Separates the two core questions: "Who needs help now?" vs.
"How did the team perform over time?"
