+/**
+ * CanvasMinimap — bottom-right corner overview of the whole canvas with a
+ * draggable viewport rectangle.
+ *
+ * Geometry mirrors the canvas:
+ *   .canvas-world is 4000×3000 px in world space.
+ *   .canvas-content is the viewport, sized to the available area at runtime.
+ *   .canvas-world's transform is `translate(pan.x, pan.y) scale(zoom)`.
+ *
+ * The minimap is MINIMAP_W × MINIMAP_H. SCALE = MINIMAP_W / WORLD_W = 0.05.
+ * A world point (wx, wy) renders at (wx * SCALE, wy * SCALE).
+ *
+ * The viewport rectangle drawn inside the minimap shows what fraction of
+ * the world is currently visible:
+ *   rect.x = -pan.x / zoom * SCALE
+ *   rect.y = -pan.y / zoom * SCALE
+ *   rect.w = viewport.width  / zoom * SCALE
+ *   rect.h = viewport.height / zoom * SCALE
+ *
+ * Interaction:
+ *   - Mouse / touch down OUTSIDE the rectangle → teleport: re-center the
+ *     viewport on the clicked world point.
+ *   - Mouse / touch down INSIDE the rectangle → drag mode: live-pan the
+ *     canvas. Inverse of (delta in minimap space) → world delta.
