`place="bottom"` ignored --material-bottom-bar, so a floating toolbar overlapped
the shell's navigation bar and a docked one landed squarely on it. Both now clear
it — max(), not a sum, since that height already swallows the bottom safe area —
and the docs say what M3 says: never show a docked toolbar and a navigation bar
together. Plan: docs/plans/material-3-alignment.md, step 14 (navigation N-02).

M3 Expressive top app bars (small, centered, medium and large flexible,
search) that collapse with CSS sticky, docked and floating toolbars,
primary and secondary tabs with a view-transition indicator, section
navigation, the account menu and theme toggles.
