// Classification-markings constants
//
// The classification system uses two linked property-field "object types":
//
//   1. System field  — drives the GLOBAL banner. Linked to the server-side
//                      template and inherits its options/colors.
//   2. Channel field — drives PER-CHANNEL banners. Also linked to the
//                      template and inherits its options/colors.
//
// Both fields share the same field name on the server and are distinguished
// only by their object_type ('system' vs 'channel'). They are also scoped
// server-side as system fields, so they share the same field-level target
// attributes (`target_type='system'`, `target_id=''`). Property *values* for
// the system field are stored on the dedicated system endpoint and use the
// sentinel target_id 'system'.
// ---------------------------------------------------------------------------

// Property-field group identifying all classification-markings entities.
// Classification is one tenant of the shared access_control group, so the name
// and the banner actions are defined once, alongside the generic channel
// attributes, and re-exported here for the existing classification callers.
