/* ============================================================
   ConvertICO converter core - styles (added 2026-10-06)
   Every page built on the shared core (_ci_tool.php + /scripts/ci-core/).
   Page parts are scoped under .ci-page (the .tool-container), the tool
   UI under .ci (#ciTool). Look copied from avif-to-png / psd-to-png
   (2026-10-06). One input colour per page: --ci-accent (set inline on
   .ci-page and from the config on .ci); every shade is derived with
   color-mix(). Light default, dark via [data-theme="dark"].
   Single colours, no gradients, no 4px side borders.
