/* The screens — specs/ux.md §4, from specs/design/grouped.html.
 *
 * The arrangement is the platform's grouped list, and it is four rules:
 *
 *  · the page is sunk and the content floats on it, as cards with a gutter
 *    rather than bands running edge to edge;
 *  · the section label sits above its card, in the page — that is what makes a
 *    list read as a group instead of as a banded table;
 *  · separators start where the text starts, not at the edge of the card;
 *  · one tint, on anything that can be touched. Everything else is ink and grey.
 *
 * The palette is tokens.css and is not restated here. What this file owns is
 * density, which is the thing that deliberately did not travel from the Mac:
 * 44 px is the floor for anything tappable, and titles get the full width
 * because they are what is actually read.
