`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).
