 * nav.css — Shared navigation bar for Ray pages.

 *   - optional left-side prepend element (e.g. index.html's sidebar toggle)
 *   - <div class="nav-links"> with nav pill links
 *   - <div class="spacer">
 *   - <div class="user-info"> with avatar, name, settings, sign-out
 *
 * Individual .nav-link pill styling lives in common.css.
 * Toolbar button base styling (.btn-toolbar) also lives in common.css.
