+## Mouse input handler for Match3 gameplay
+##
+## Static methods for handling mouse interactions in Match3 games.
+## Converts between world coordinates and grid positions, performs hit detection on tiles.

+## Usage:
+##   var tile = Match3InputHandler.find_tile_at_position(grid, grid_size, mouse_pos)
+##   var grid_pos = Match3InputHandler.get_grid_position_from_world(node, world_pos, offset, size)
