§2 · HTTP Session Tokens

2. Strictly Necessary Cookies

The following first-party cookies are essential for core platform operation and security:

Your browser’s `localStorage` and `sessionStorage` store the following prefixed keys directly on your device:

`ncs:recent`	`localStorage`	Maintains up to 6 recently inspected or launched specimens for your personal tray.

§4 · Default-Denied Specification

4. Google Consent Mode v2 Architecture

On every page load, prior to any optional script execution, our document `` initializes Google Consent Mode v2 in a strict default-denied state:

gtag('consent', 'default', {
  'analytics_storage': 'denied',
  'ad_storage': 'denied',
  'ad_user_data': 'denied',
  'ad_personalization': 'denied',
  'wait_for_update': 500
});

§5 · User Autonomy

5. Browser & Platform Controls

You can inspect and toggle your analytics consent status in real time on our interactive Consent Mode v2 Controls page, or clear site storage at any time through your browser’s privacy settings.

§6 · Governance
