Does Frozen Fortress trigger before or after scoring for holding battlefields?

Ruling: Frozen Fortress triggers and resolves before scoring occurs. The Beginning Phase consists of two steps: the Beginning Step (where "at the start of Beginning Phase" effects like Frozen Fortress trigger), followed by the Scoring Step (where holding and "when I hold" abilities occur).

Sequence:

• Beginning Step: Frozen Fortress triggers, is placed on the chain, and resolves, dealing 1 damage to each unit
• Scoring Step: The turn player holds all battlefields they control and scores Victory Points
• "When I hold" abilities trigger after the hold action completes and points are gained
