/* Login page.
 *
 * The one screen with no sidebar and no top bar, so it is the easiest place
 * for the UI to drift. It is built in the same visual language as the
 * 19-lenses report: the blue-tinted cover gradient, the accent hex mark, Syne
 * for display type and Inter for everything else, small uppercase labels and
 * the 4px accent bar.
 *
 * Every colour comes from the tokens in dark-mode.css, so the page follows
 * the theme the user picked inside the app. Bootstrap is deliberately not
 * loaded here — like the report, the page is small enough to style directly.
