+# F-101 — Descripción de producto justificada en el frontend
+
+## Alcance reducido por el operador
+El renderizado actual de descripciones IA ya funciona; solo se pide alineación justificada.
+
+## Cambios
+- `frontend/src/app/products/[slug]/page.tsx`: `text-justify` en el bloque de descripción.
+- `storefront/src/app/productos/[slug]/page.tsx`: `text-justify` en el bloque de descripción (consistencia SEO).
+
+## Evidencia
+- Builds de frontend y storefront OK; ambos servicios 200 tras restart.
