   10MS TOWNHALL 2023 — "One Evening". The page is the venue at night: a
   guest's walk from the invite to the group photo. The event's own kit only:
   near-black, 10 Minute School red, white, Poppins ExtraBold, and the
   outlined "Together Towards Tomorrow" line as the backdrop. Gold appears
   once, for the Legacy Club.
