 * Deliberately standalone rather than layered on site.css: the splash page is
 * a fixed, non-scrolling composition (`overflow: hidden`, everything
 * `position: fixed`), which is exactly wrong for a long document.
 *
 * These pages are read by two audiences with equal claim on them: someone
 * deciding whether to trust the app, and an App Store reviewer checking the
 * URL resolves. Both are served by plain, high-contrast, unfussy text.
 *
 * They follow the splash's mode. The same inline boot script runs here - not a
 * copy of it: render.py lifts it out of index.html at build time, so the two
 * pages cannot drift and the one test covers both. localStorage is per-origin,
 * so a choice made on the splash is already in force by the time a visitor
 * lands on /privacy.
