Greta is an AI. She writes back in text — no synthetic voice, because the voice is the part that costs real money and we'd rather spend it on rooms. What you tell her is kept with your card and Mike reads it. Only your name and one line ever show on the public wall.
One photo, taken now or picked from your camera roll. Yours only — please don't put anyone else on the wall without them standing here.
This is what goes on the wall. Change anything you like.
The public wall shows your name, your photo and that one line — nothing else. Your conversation with Greta and your email go with the card where only Mike and his AI colleagues see them, and the email is only ever used to send you your room. Your card comes down the moment you ask.
