Route groups
Primary groups include `(dashboard)`, `(marketing)`, `(auth)`, and `(public)`.
Module routes should live under `(dashboard)/(modules)` unless there is a clear reason otherwise.
Shell-backed modules
Activity-bar modules use the shared modern shell, sidebars, and workspace layout framework.
Special modules like `cpanel` still follow shell rendering and role gating conventions.
Documentation sources
Keep `docs/architecture/ROUTES.md` aligned with route additions and redirects.
Use implementation changelogs for delivery snapshots and `docs/WORKLOG.md` for chronological context.
