<p>4x1 with parallel and orthogonal items. Items orthogonal to the baseline-axis will use a synthesized baseline (border-box 'under' edge).<br>No item shares any row-like Baseline Context. All items share 'first-column' Baseline Context.<br>The 'justify-self' property (orthogonal to the shared context) aligns all items along the baseline-axis using the column-like baseline.</p>
