/*
 * BotGuard overlay styles.
 *
 * Served as a file rather than injected as a <style> element so the module works under a
 * Content-Security-Policy without 'unsafe-inline' in style-src. Everything the operator can
 * configure - colours, radius, width, blur, accent - comes through CSS custom properties,
 * which JavaScript sets with element.style.setProperty(). CSP governs <style> elements and
 * style attributes that arrive in markup; it does not intercept CSSOM writes, so this stays
 * fully configurable while remaining policy-clean.
