/* The stylesheet of every page of the system (not the landing page, not the
   calculator). One file, built from a few components; pages only combine
   them. See docs/dev/frontend.md#stylesheet.

   Rules that keep pages tidy at any width:
   - Nothing styles bare elements beyond typography and form fields: a
     button looks like a button because it has .btn and a variant.
   - Every button has the same box (border, line height, min height), so
     buttons side by side always share their height and centre line.
   - Buttons that belong together go in a group (.button-stack, .button-row,
     .button-grid), which gives them equal widths and aligned edges.
   - Side margins come from the page container only (--gutter). */
