/**
 * QR panel on wp-login.php.
 *
 * Sized to sit inside the 320px #login column alongside the standard form.
 */

/*
 * Side-by-side layout.
 *
 * The panel and the login box are wrapped in this row by the script. It wraps
 * on narrow screens so the panel drops underneath rather than squeezing the
 * form, and it leaves #login's width and padding alone so any site-side
 * customisation of the login box still applies.
 */
/*
 * Three columns: an empty one, the login box, an empty one. The two outer
 * tracks are equal, so the login box lands dead centre of the page and stays
 * there whether the QR panel is shown or not. The panel then sits inside an
 * outer track and hangs off the middle without shifting it.
 *
 * A flex row cannot do this: it centres the pair, which drags the login box off
 * to one side as soon as the panel appears.
 *
 * Bottom edges are aligned rather than centres, so the two boxes sit on a
 * shared baseline instead of both ends looking ragged.
