Navigation base, the way Firefox does about:preferences#privacy: the
address bar follows the Settings page (theseus://settings/privacy) and
the hash mirrors it, so every page has a link; a page can have
sub-pages (theseus://settings/privacy/exceptions) with a breadcrumb and
a back arrow; open-settings and theseus:// links accept the two-level
slug.
Privacy now reads top-down: a "Theseus is on guard" card (Shield and
its running total, cookie pop-ups answered, Tor state, version), then
Tracking protection with the Shield and Cookie Pop-ups cards moved here
from Performance and a Manage exceptions sub-page listing the sites
each add-on was told to leave alone (remove to protect again), then
Device access, Anti-fingerprinting, Network (Tor switch and the VPN
panel) and Browsing data. Performance is about resources again.
