Consider self-hosting Bootstrap and related assets
A user wrote in noting that the layout on pages like https://metromapmaker.com/calendar/2025/3/11/ wasn't correct; looking at their provided screenshot, I didn't see the icons on the buttons loaded either, so I suspect the Bootstrap CSS loaded from the CDN was failing to load.
While the CDN doesn't show any downtime/outages, and while I'm using subresource integrity, self-hosting would prevent whatever connection issues might have happened here, though perhaps at the cost of a bit of speed.
