@@ -75,3 +75,20 @@ For `sprimo-tauri`, when manifest `image` is exactly `sprite.png`:
   - `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`).

+## Recommended 7x8 Row Semantics
+
+For `sprite.png` packs using the fixed `8x7` topology, the project convention is:
+
+- row 1 (`0..7`): `idle`
+- row 2 (`8..15`): `happy`, `love`, compatibility alias `active`
+- row 3 (`16..23`): `excited`, `celebrate`, compatibility alias `success`
+- row 4 (`24..31`): `sleepy`, `snoring`
+- row 5 (`32..39`): `working`
+- row 6 (`40..47`): `angry`, `surprised`, `shy`, compatibility alias `error`
+- row 7 (`48..55`): `dragging`
+
+Default one-shot policy:
+
+- `celebrate` and `success` are one-shot.
+- other row animations loop by default.
