+// Real path: 设置 → 使用统计 → 定价配置. The editable Pricing tab (#2015 / PR #4164,
+// integrated into the features/usage slice) reads ONE Host-backed effective
+// pricing snapshot from the real embedded Runtime Host — no bridge stub. Per the
+// maintainer direction on #2218 the surface is OVERRIDES-ONLY: the table lists
+// only the user's custom rows, and the ~1.4k built-in catalog is reached only
+// through the Add flow's Typeahead picker (never rendered as a table, so nothing
+// heavy renders). This exercises #2015 acceptance #2 (the tab is not time-scoped:
+// the Usage date range/summary toolbar is gone) and #11 (the editor returns focus
+// to the trigger that opened it — real Electron focus the linkedom harness cannot
+// honestly exercise), plus the overrides-only shape and the picker/manual Add UI.
