The CTF board

The CTF board (Threat Intelligence → CTFs tab; the menu's CTF Board item lands there) pulls the CTFtime API into a local cache on an hourly cadence — outbound-only, no accounts, no keys, and a dead source is a named sentence with the last-good board still up.

Cards carry everything the listing gives — name, start and finish in your timezone, format (Jeopardy / Attack-Defense), online or on-site with its location, weight, restrictions, organizers, logo, description, prizes where listed, and the CTFtime link — split into Running now and Upcoming; past events fall off. Ask Navi what's on or what's worth playing and she answers from the board, citing the listing and its fetch stamp.
