/*
 * Modern wizard shell: step sidebar, card headers, and the "can't skip
 * ahead" validation banner. Originally built for the Training Provider
 * (SDP) wizard and extracted here so every step-wizard form can opt in by
 * adding the "modern-wizard" class instead of duplicating the rules.
 *
 * Colours come from the brand tokens in _Layout.cshtml (--nexus-*) and the
 * theme family (--vz-*), never literals: the gradient here used to be the
 * old flame orange, which survived the indigo rebrand precisely because it
 * was hardcoded - and the light greys stayed light in dark mode.
