- * |
- * `seamed`: The header is presented as seamed with the panel. |

- * `waterfall`: Similar to standard mode, but header is initially presented as |
- * seamed with panel, but then separates to form the step. |

- * `waterfall-tall`: The header is initially taller (`tall` class is added to |
- * the header). As the user scrolls, the header separates (forming an edge) |
- * while condensing (`tall` class is removed from the header). |
- * |
- * `scroll`: The header keeps its seam with the panel, and is pushed off screen. |

- * `cover`: The panel covers the whole `paper-header-panel` including the |
- * header. This allows user to style the panel in such a way that the panel is |
