Cookie Consent Banner

Create a lightweight cookie consent banner for my website as ONE self-contained snippet (HTML + <style> + <script>, every class prefixed "cc-"), with no external libraries.

- Website / business: [Your business name]
- Brand colour for buttons and toggles: #2563eb
- Privacy policy URL: [your privacy policy link]

REQUIREMENTS
- A bottom banner (max 980px, centred, dark #0F172A, 20px radius) with a short plain-English message, a privacy-policy link and 3 buttons: "Reject non-essential", "Customise" and "Accept all" — Accept and Reject must be equally easy to choose
- A "Customise" dialog (role="dialog", aria-modal, focus moved inside, Escape closes it) with toggle switches for Essential (always on, disabled), Analytics and Marketing, plus "Reject all" and "Save choices" buttons
- Save the choice in localStorage under a versioned key ("cookie-consent-v1") with a timestamp; don't show the banner again until the version changes
- IMPORTANT: block analytics and marketing scripts until consent. Use the pattern <script type="text/plain" data-consent="analytics">…</script>; after consent, turn each allowed tag into a real <script> (support both inline code and src)
- After a choice, show a small "Cookie settings" button in a corner to reopen the preferences
- On mobile the buttons stack full-width; respect prefers-reduced-motion

Return the snippet in one code block, then show exactly how to wrap a Google Analytics tag so it waits for consent.
