Settings is organized into sections in a left rail (apps/web/src/components/settings/shell/settings-nav-rail.tsx, driven by apps/web/src/lib/settings-nav.ts): My account, Company (covered in detail by First-day setup), Team, Sales, Operations, and more, down to Integrations. Each top-level section groups several sub-pages (e.g. Team groups Users, Roles, Project roles, and Permission matrix); which sections and sub-pages a given user can see is permission-gated the same way top-nav modules are, per Concepts: roles and permissions.

TODO(owner, likely product): write the full guide as an orientation tour covering every section in settings-nav.ts (Sales, Operations, and whatever comes after Team in the rail), not just Company, so a new Owner or Admin knows where to configure each part of the product before diving into individual how-tos.
