+# F-122 — Quitar warning de variantes heredadas
+
+## Cambios
+- `apps/admin/src/features/products/components/sections/PriceStockSection.tsx`:
+  - Eliminado `extraVariants` state.
+  - Eliminado el `setExtraVariants(...)` del useEffect de carga.
+  - Eliminado el bloque JSX `{extraVariants > 0 && (<p>⚠️ Este producto tiene X variante(s) heredada(s)…</p>)}`.
+
+## Evidencia
+- `npx tsc --noEmit` (apps/admin) OK.
+- `grep` confirma que no quedan referencias a `extraVariants` o al texto "heredada".
+
+## Notas
+- El modelo actual tiene una sola variante por producto. El warning era ruido heredado de cuando el modelo tenía varias.
+- Si en el futuro se reintroducen variantes múltiples, el producto editorial se ajusta por separado.
