   CSS Color Scheme Editor - stylesheet (rebuilt 2026-10-05)
   Everything is scoped under .cce / .cce-*; the shared header, footer,
   FAQ and related-tools pills come from styles/custom_styles.css,
   which loads first. Blue accent, single colours for titles and icons,
   no 4px side borders. Dark mode via [data-theme="dark"], light default.
