"""Construye un catálogo de partidos (liga/temporada/fecha/local/visitante) para
TODAS las ligas Opta, a partir de los nombres de los xlsx en Azure
(raw/eventing/opta/Partidos/{liga}/{temporada}/{fecha} - {local} vs {visitante}.xlsx).

Listar nombres es barato (no descarga). El catálogo alimenta los selectores de la
web (ligas/temporadas/equipos/partidos) para todas las ligas, incluso las que no
están en el dataset del modelo. Sale a vendor/data/matches_catalog.parquet (chico).

Uso: python scripts/build_matches_catalog.py
