Meeting-safe

Meeting-safe is our shorthand for a device you can operate without anyone else in the room noticing — no audible click, no visible motion above the desk line, no risk of dropping and rolling away.

It's a judgement call made after real use, not a fixed threshold on any single measurement. A quiet spinner can still fail "meeting-safe" if it needs both hands to start, and a loud clicker can pass if it's used one click at a time under a table. We record it as measured.meetingSafe alongside loudness and size, once we've actually tried the device in that setting.
