name: Refresh MCU data

# Pulls fresh data from TMDB (posters, ratings, runtimes, release dates,
# IMDb ids, synopses) into mcu-data.json once a day. If anything changed,
# it commits the update. NOTE: this repo has no Vercel git integration, so
# the commit alone does NOT deploy — pull it locally and run `vercel --prod`
# to actually ship the refreshed data.
# Needs a repo secret: TMDB_API_KEY
