/*
 * The "Request a signature" form, as visitors see it. It lives inside other
 * people's themes, so it takes the theme's typeface and text size and brings
 * only Salsox's teal, square corners and its own spacing. Every rule is
 * scoped under .salsox-sign so it neither leaks into the theme nor depends
 * on it.
 *
 * The one distinctive element is the signing line: the button sits under a
 * dashed rule, the way a paper form marks where to sign. Phone first:
 * fields stack and the button fills the width; from 34rem of container
 * width the fields sit side by side. Motion only answers the
 * visitor (the confirmation appearing) and is off under reduced motion.
