/* Dropsi.
 *
 * The Filesharing design system, reduced to what one page needs and rebuilt so
 * that Internet Explorer 11 renders it. Two rules follow from that and run
 * through the whole file:
 *
 * 1. EVERY COLOUR IS DECLARED TWICE - the fixed value first, the custom
 *    property second:
 *
 *        background: #f0921e;
 *        background: var(--accent);
 *
 *    IE 11 has no custom properties, so it drops the second line and keeps the
 *    first. Every other browser applies the second and gets the theme. No
 *    browser sniffing, no second stylesheet, no build step. When you change a
 *    colour, change BOTH lines - a var-only edit is invisible until somebody
 *    opens the page on Windows 7, which is the last place anybody looks.
 *
 * 2. NO `gap`, NO CSS GRID. Spacing is margins, layout is flexbox. IE 11
 *    supports neither `gap` nor modern grid, and carrying two layout systems
 *    behind an @supports query means the fallback is never the one anybody
 *    looks at. One code path, tested everywhere.
 *
 * Dark theme lives in a prefers-color-scheme block, which IE 11 skips - it
 * stays on the light palette, which is correct for the machines in question.
