/*
 * "Stay updated" band (theme 0.25.0): top of the footer on Home, About and Contact (GPIPL Settings →
 * Stay updated band). Lives inside the dark footer, so colours come from the dark role tokens.
 * Also styles the "Suggest a website improvement" dialog (printed at wp_footer, light scheme).
 * Layer "polish" so it refines footer and form styles without !important.
