roomPosterSelector(_:)

func roomPosterSelector(_ req: Request) async throws -> View

GET /admin/eventfeedback/roomposters

Displays a form pre-filled with all the room names that are hosting shadow events, scraped from the schedule. After editing, this will go to a print-optimized HTML document with one room poster per page. Each room poster has the name of the room, instructions for the host, and a QR code that goes to the feedback flow. The URL embedded in each QR code has a query option specifying the room name, which allows the event selector page to filter the list of events to those happening in that room.
