/* ============================================================
   AVIF Background Remover - stylesheet (rebuilt 2026-10-02)
   Replaces style.css. Everything is scoped under .abr / .abr-*;
   the shared header, footer, FAQ and related-tools pills come from
   styles/custom_styles.css. Green accent like the other background
   removers, single colours, no gradients, no 4px side borders.
   Dark mode via [data-theme="dark"], light is the default.
