/**
 * FormsHub: the login and register overlay.
 *
 * Ported from OSS CE Modules v3.9.1. D-097.
 *
 * ── Layout that cannot jump ─────────────────────────────────────────────────
 *
 * A full-viewport scroll area with fixed top padding, and a dialog at
 * `margin: 0 auto`. The dialog's top edge stays the same distance from the top
 * of the scroll area however tall it grows; when it outgrows the viewport the
 * scroll area scrolls rather than the dialog repositioning.
 *
 * Centring with flex or transforms instead is what produces the jump when a
 * validation message appears and the form gets taller.
