+Fusion Accounting Core
+======================
+Foundation for the Fusion Accounting sub-modules. Owns:
+- Three security groups (User, Manager, Admin) shared across all fusion sub-modules
+- Shared-field declarations on Community account models so deferred-revenue,
+  signing-user, and similar Enterprise-extension fields survive Enterprise uninstall
+- Runtime helper for detecting Odoo Enterprise accounting modules
+
+This module never works alone. Install fusion_accounting (the meta-module)
+or one of fusion_accounting_ai, fusion_accounting_bank_rec, etc.
