public class MazeDisplayer extends javafx.scene.canvas.Canvas
A resizable JavaFX Canvas that renders a Maze, the player, the goal, an optional Solution overlay, and an optional set of visited cells for the search visualizer.

Exposes JavaFX properties for everything that changes at runtime so the controller can bind it to the ViewModel — setting any property triggers a redraw.

Sprite handling: if /mazealgo/view/images/wall.png, /player.png and /goal.png are on the classpath they're used; otherwise the displayer falls back to colored shapes (dark slate walls, blue player circle, green flag-style goal). The fallback ships with the repo so the UI works out of the box without sourcing third-party assets.

Layer order (back to front): floor, walls, grid lines, visited overlay, solution path, goal sprite, player sprite. The visited overlay sits under the solution so the solution always reads on top.
