+  Design ONLY a single applied-filter tag chip that lives in a list-of-
+  applied-filters bar above a dashboard data table. The chip is a
+  fit_content blue-100 background pill with 12px corner radius and 6px
+  gap between its two children:
+    1. blue-600 13/500 label "Status: Active"
+    2. trailing 14×14 lucide "x" icon (close affordance, blue-600)
+  Padding 4px vertical, 10px horizontal. Do NOT render the surrounding
+  filter bar, other applied-filter chips, the table itself, or the
+  page chrome — just this one closable tag chip.
