Benchling Custom Entity API
A flexible, user-defined entity type in Benchling's Registry. Unlike specialized entity types such as DnaSequence or Molecule, CustomEntities allow organizations to model any kind of scientific or business object using configurable EntitySchemas (see `schema`). CustomEntities support customFields for storing structured data, can be organized into Folders and Projects, and integrate with Benchling's collaboration, search, and audit systems. They are commonly used to represent cell lines, reagents, instruments, or any domain-specific items that don't fit predefined entity categories.
