/*
 * Vesper — getvesperapp.com
 *
 * Palette and radii are lifted from the desktop app's Nocturne stylesheet so
 * the site and the product look like one thing: surface #232532, text #e9e9ed,
 * the accent rotated to green (#00aa8f / #10b194), radii 4 / 8 / 14. The page
 * background is a shade deeper than the app's #161826 because a full-bleed web
 * page needs more room underneath the content than a 1200px app window does.
 *
 * No webfonts, no scripts, no third-party anything: the privacy page claims the
 * site loads nothing from another origin and build.mjs fails the build if that
 * stops being true.
