+For `sprimo-tauri`, when manifest `image` is exactly `sprite.png`:

+- runtime uses a fixed grid topology of `8` columns x `7` rows.
+- frame size is derived from actual image dimensions:
+  - `frame_width = image_width / 8`
+  - `frame_height = image_height / 7`
+- manifest `frame_width` and `frame_height` are ignored for this case.
+- animation frame indices are validated against the fixed grid frame count (`56`).
