Scenario: An enemy unit within LoS and Range 2 of a unit with a standby token performs a move action, thus triggering the standby. The friendly unit spends the standby and decides to take a move action. If the unit with the standby is Rebel Boba Fett, he can replace the move action with Card Action: Jump, as the Jump Keyword says, "A unit that has the Jump X keyword can perform the Jump X card action any time it could perform a move action."
Now, here's the question: If the unit with the standby were instead Geonosian Warriors with the free action: Jump, would they be able to do the same -- spend the standby to jump? The reason I ask is because the CRB section on Free Card Actions says, "A unit may only perform free actions during its Perform Actions step" -- we don't have a can/cannot, so which rule takes priority? can the "Jump X replaces any move action" supersede the "Units may only perform free actions during its Perform Actions step?" --- So to ask the question in a clear, unified sentence, "Can a unit with [free card action]: Jump X use the Jump keyword outside of its Perform Actions step, like while spending a Standby token?
--In-game, we have examples of free card actions being performed outside the Perform Actions step, like R2-D2's Smoke screen card, but that one specifically calls out a timing window for that free action, whereas triggering a standby doesn't.
