Type Alias DataWindowDirection

Direction of the data-collection window relative to the run date.

• forward — future-facing (e.g. week-ahead, year-ahead)
• backward — past-facing (e.g. week-in-review, year-in-review)
• span — anchored at run date but spanning both directions (e.g. election-cycle uses ±6 months around the election week)
• point — single point in time (e.g. breaking-news at run-time)
