<p>4x1 with parallel items. <br>No item shares any row-like Baseline Context. All items share 'first-column' Baseline Context.<br>Orthogonal items don't participate in baseline alignment in the column-like baseline; since no item shares row-like Baseline Context, neither 'aling-self' or 'justify-self' apply.</p>
