The rule that runs list_styles safely

list_styles is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Framesail, apply this rule, and every list_styles call is checked against it from then on.
