[ENHANCEMENT] Optional slide-pointing rehearsal record for the organizing guide #16208

The organizing guide's Video recording and streaming section recommends rehearsing before a livestream. Please consider an optional blank record for checking what an indicated slide detail looks like to an in-room viewer, a remote attendee and a permitted rehearsal recording.

Resource: Hybrid-room pointing rehearsal record — Light Tracer, two-page PDF, CC BY 4.0. It is free to read and print without an account or purchase.

The record has fields for the presentation and meeting apps, shared source and pointing tool, then checks of the room, shared and recorded views. A presenter and observer can note one change and recheck it. The checks start as Not tested. This is a blank rehearsal aid, with no equipment, research or accessibility-certification result claimed.

If useful, an optional resource link could sit beside the existing rehearsal guidance. This issue follows CONTRIBUTING's request to discuss a site-wide change before submitting a PR; no event content, organizer list, sponsor details, recording policy or site code has been changed. It does not request an event listing or organizer status.
