+/// Per-dimension alignment of a loop tile size to a `linalg.pack` /
+/// `linalg.unpack` inner tile size, supplied by the caller (which performed the
+/// tiling and knows both the tile sizes and the inner tiles) so that
+/// pack/unpack TilingInterface implementations need not re-derive it from the
+/// materialized IR. An absent entry (or `Unknown`) means "no information": the
+/// implementation must fall back to its prior behavior for that dimension.
+///   - `Multiple`: the loop tile size is an integer multiple of the inner tile.
+///   - `Equal`:    the loop tile size equals the inner tile size.
