+## A fuzzer that generates random Vector2 values within a specified rectangular range.[br]
+##
+## This is particularly useful for testing 2D physics, movement
+## systems, UI positioning, sprite coordinates, or any code that processes 2D vectors.[br]
+##
+## The fuzzer generates vectors where each component (x, y) is independently randomized
+## within its respective range, creating a uniform distribution over the rectangular area.[br]
+##
+## [b]Usage example:[/b]
+## [codeblock]
+## # Test 2D movement within screen bounds
+## func test_movement(fuzzer := Vector2Fuzzer.new(Vector2.ZERO, Vector2(1920, 1080)), _fuzzer_iterations := 200) -> void:
+##     var position := fuzzer.next_value()
+##     player.set_position(position)
+##
+## [/codeblock]

+extends Fuzzer

+## Minimum bounds for the generated vectors (inclusive for both x and y).
+var _from: Vector2
+## Maximum bounds for the generated vectors (inclusive for both x and y).
+var _to: Vector2

+func _init(from: Vector2, to: Vector2) -> void:

+## Generates a random Vector2 within the configured rectangular range.[br]

+## Returns a Vector2 where each component is independently randomized:[br]
+## - x: random float between [code]_from.x[/code] and [code]_to.x[/code][br]
+## - y: random float between [code]_from.y[/code] and [code]_to.y[/code][br]
+##
+## The distribution is uniform over the rectangular area defined by the bounds.[br]

+## @returns A random Vector2 within the specified range.
