How the location is sourced. Drives how value is interpreted: free_text treats value as a literal location string, office resolves it to an organization office id, and custom_list resolves it to a job_board_custom_locations id. Must match the parent job board's configured location strategy.

Location value, interpreted per type. For free_text, the candidate-facing string (e.g. Remote (US)). For office, the integer office id as a string. For custom_list, the integer job_board_custom_locations id as a string — and the custom location must belong to the same job board as the post.
