Prototype the launch demo and support entry point #24

Part of OpenBeat v0.1.0 public launch map.

Question

What is the smallest launch demo and support entry point that lets a first-time visitor understand OpenBeat's core workflow, see its limitations, and file a useful compatibility report?

Prototype brief

Use $prototype to produce a cheap, reviewable artifact: proposed README placement and media treatment plus the bug-report form fields and support copy. Reuse existing assets where possible; do not implement the final repository changes in this ticket.

Resolution should record

• The approved demo format and placement.
• The approved support path and bug-report fields.
• How known limitations appear near the download path.
• A link to the prototype artifact.

This is HITL: the maintainer must react to the prototype.

Handoff

Implement the approved launch demo and support entry point implements the approved artifact.
