Five or more sections wrapped onto a 3- or 4-column grid, which left the tab bar's divider under the last row only and stranded every upper row's active indicator against nothing. From five they are now what M3 prescribes and its accessibility page defends: a scrollable tab bar, each tab as wide as its label, offset 52dp. Four or fewer still share the row. The 20px icons take the 20 cut. Plan: docs/plans/material-3-alignment.md, step 21 (navigation N-16).
