Calendar
========

You can integrate an externally-hosted event calendar with sewifurs.org by
setting `CALENDAR_URL`. The calendar will be displayed below the chat directory.
If the calendar is hosted on Google Calendar, a CSS hack is applied to make it
render in dark mode if sewifurs.org itself is in dark mode.

Calendar webpages must allow embedding in an `iframe` on the `sewifurs.org`
domain. If you are having trouble, check if either of these are set on the
target webpage:

- `Content-Security-Policy: frame-ancestors … <https://developer.mozilla.org/en-US/docs/Web/HTTP/Reference/Headers/Content-Security-Policy/frame-ancestors>`_
- `X-Frame-Options: DENY/SAMEORIGIN <https://developer.mozilla.org/en-US/docs/Web/HTTP/Reference/Headers/X-Frame-Options>`_
