Firefly (fan expansion for Hive)

Description

--- The Firefly exhibits unique vertical movement in Hive, ascending rapidly to the top and restricted from ground-level circling. Key mechanics include: - *Ascension from ground*: Moves exactly two spaces upward onto the top of the Hive. - *Top-level traversal*: While on the Hive, advances one space before inevitably dropping down. - *Ground-level restriction*: Prohibited from moving around the Hive at ground level. The Firefly's movement rules emphasize verticality and limitation: from ground level, it precisely ascends two spaces to position itself atop the Hive. Once elevated, it can only progress one space across the top surface prior to dropping back down. Notably, it is entirely barred from circumferential movement around the Hive while at ground level, enforcing a specialized, non-horizontal path that integrates height dynamics into gameplay strategy. ---
