Showtimes are fetched from Shaw, Golden Village and Filmhouse, and the
theatre & music listings from Esplanade and Marina Bay Sands, once a day
at 2pm and stored, rather than on every visit. This optimises the amount
of data pulled from the venues and makes the page load much faster.
The trade-off: listings can be up to a day old, so seat availability
isn't shown. If something looks off, you can re-fetch everything —
movies and theatre — now.
