Set up a rooms zones

Steps

1. 1 Venue Manager Open the venue 0:03 ▣

   Details, capacity, layout — and Zones, because a zone is a part of a room. The schema has known that since plan 23; the console is where a manager finally sees it.

2. 2 Venue Manager Add a Mezzanine to this room 0:05 ▣

   The code derives from the venue slug and is permanent — it is written into every ticket, and the scanner authorizes by comparing that exact string.

3. 3 Venue Manager It appears here 0:07 ▣
4. 4 Venue Manager And nowhere else 0:10

   Scoping is the substantive half: a venue page listing every zone on the platform would be longer, not clearer.

5. 5 Administrator The door console names zones; it does not own them 0:15 ▣

   What stays here is the zone SELECTOR for readers — the door genuinely needs to name a zone. Managing them lives with the room.
