where do custpage variables come from

AI generated answer (using internal Slack threads):

'custpage' variables in NetSuite are typically added dynamically via SuiteScript code or workflows. They are not part of the actual definition of the record itself, hence they might not be directly referenceable via saved searches or customizable in the usual sense. These variables are often used to add custom fields to a form or record. The 'custpage' prefix is a standard naming convention in NetSuite for custom fields added via script.
