This skill draws on established Salesforce Industries patterns for callable Apex implementations,
including the `System.Callable` interface, `VlocityOpenInterface`, and `VlocityOpenInterface2`
extension points used in OmniStudio and Industries integrations.

The guidance, migration patterns, and bundled examples reflect best practices for secure,
deterministic callable implementations across Industries extension points such as OmniScripts,
Integration Procedures, and DataRaptors.
