User-defined variables populated by filtering records with Whippy Query Language (WQL).
Each key is a variable name, such as available_jobs. Its value contains the filter rules that define which
records populate the variable and may also contain limit and sort.
At runtime, Whippy filters records for the current contact and, where applicable, the current agent, then makes
the results available in the agent instructions:
{{@repeat available_jobs}}...{{@endrepeat}} repeats the enclosed content for each matching record.
Fields within the repeated content can use placeholders such as {{custom.job.title}}.{{@if available_jobs}}...{{@else}}...{{@endif}} renders the first block when records match, or the
optional @else block when none match.
