Laser Grid Lock.

• Steel blocks absorb light. Free tiles wrap around them.
• Solrock patrols one tile, then rotates its beam arrow clockwise.
• Minior sends cyan counterclockwise and amber clockwise, perpendicular to the incoming beam.
• Lunatone absorbs light. Four consecutive shift hits trigger EMP. Missing one hit clears charge.
• Rayquaza absorbs any beam that hits it. Delta Stream seals the portal for three turns and locks a rotating row. Columns stay usable. The fourth turn opens the portal and releases every row: arrive with the full circuit on that turn. Undo restores the storm phase.
• An amber core needs amber light. A prism portal needs both colors from different angles in the same turn.
• Numbered nodes must be visited in order on one branch, with a mirror between each. Rails move every two shifts.

Each legal shift moves tiles, advances patrols, rails and the storm, traces all beams, then charges Lunatone. A completed circuit wins before EMP. Reset restarts the level; Undo restores the previous board and all entities. Moves counts both shifts and undo actions; Turn rewinds on undo.
