See everything. Change nothing.
Nobody can change this wall from here

There is no sign-in, no post box, no edit or delete buttons. That is not a styling choice, it is the permission model: this page never asks for write access, and Dillo enforces the schema permissions on every request, so even a hand-built request cannot change a note it does not own.
Think lobby screen, shared monitor, or a link you send to people who only need to see.
