Proposed changes. One of them addresses the public debug page.

change wallpaper from blue to green
set debug = false
set public_debug_page = false
remove account_name and account_secret

Activity exposure: the public page prints session_store=memory because public_debug_page is true.
The change that removes that page is public_debug_page = false together with debug = false.
The wallpaper change leaves the page in place.
