/* ========================================================================= RonRov accessibility widget — professional redesign (v2) Compliance target: IS 5568 / WCAG 2.0 AA. Key architecture note: - Color FILTERS (contrast/invert/grayscale) are applied to the page content wrapper #a11y-content (opened in inc/header.php, closed in inc/footer.php) — NOT to . Applying a CSS filter to an ancestor of a position:fixed element makes that element scroll with the page (iOS Safari bug on long pages). The widget lives OUTSIDE #a11y-content, so the floating button always stays fixed and un-filtered. - All other helpers (font scale, links, focus, motion, readable font, spacing, big cursor) stay on ; none of them create a containing block, so they are safe there. ========================================================================= */ :root{ --a11y-font-scale: 1; --a11y-accent: #1e63d6; /* AA on white (4.7:1) */ --a11y-accent-ink: #ffffff;
