/* ── CUSTOM METRICS WIDGET (Phase 2.11.5 Slice 1) ─
   List view of user-defined metrics. Slice 1 ships the bones:
   empty state, list of metrics with name + unit + type icon, a
   delete button per row, and a "+ New metric" CTA at the bottom.
   Slice 2 adds quick-log inputs inline; Slice 3 adds sparklines;
   Slice 4 adds archive + reorder. */
