 * app.css — the app shell: the frame around the sheet of paper.

 *   notes list | top bar
 *              | tool tray
 *              | banner
 *              | stage (the written or the typed view) ... side panel over its right edge
 *
 * The window never scrolls; the list, the two views and the panel do.
 * Below 1000 px the notes list is a drawer, below 700 px the panel is as
 * wide as the window. The top bar adapts to its own width, not to the
 * window: the same bar is narrow beside an open list and wide without it.
 * The widths used for that are also in js/app.js (BAR_STEPS).
 *
 * Colors come from tokens.css only.
