ideas :

• integrate better live messages (via ?allowNtfyFeedbackHUD=true , e.g. https://companion.benetou.fr/index.htm?allowNtfyFeedbackHUD=true )
• JSON editing, either as-is or via PmWiki (including raw text within JSON) or with CodeMirror as editor (just text area is plain text should be enough
• feedback intertwined per demo (based on screenshot/audio recording demos)
• richer text rendering
• couple live messages with inView(targetSelector)

done :

• hmd.link/? to share directly over same local network
• link as clickable (right now only trailing ones, and 1 link per description maximum)
• source JSON URL https://webdav.benetou.fr/fotsave/fot_sloan_companion_public/demo_q1.json
• alternative descriptions https://futuretextlab.info/1st-quarter/ (more verbose but static)
• mobile view
• linked to editor : https://companion.benetou.fr/demos_editor_example.html
