/* bootstrap-subset.css
 *
 * A minimal, self-contained replacement for the only Bootstrap 4.0.0-beta.2
 * classes this page actually uses, vendored in place of the ~140KB maxcdn
 * Bootstrap CSS. Values are copied verbatim from Bootstrap 4.0.0-beta.2 so the
 * page looks identical. The login modal/form/button classes are intentionally
 * omitted except for `.modal { display: none }`, which keeps the inert login
 * dialog hidden exactly as Bootstrap's JS-driven modal would.
