A scrollable set now starts 52dp in, so it reads as scrollable; a primary
indicator is inset 2dp at each side while a secondary one still spans the tab;
a link marked aria-current takes the active label colour the indicator already
followed; and the focus ring is 2px outside the tab, as everywhere else in the
package, paid for with 5px of room around the bar that the state layer and the
indicator reach back into.
Plan: docs/plans/material-3-alignment.md, step 21 (navigation N-10, N-18,
N-20, N-21).
