📚 Description

Privatus Analytics is cookieless web analytics. This adds it to the registry as privatusAnalytics / useScriptPrivatusAnalytics(). The site ID is rendered as data-site, a few tracker options (modules, spa, manual, domains, exclude, hash) map onto data-* attributes, and the tracker's track, pageview, props, optOut, optIn and isOptedOut calls are exposed through the composable's proxy.

Capabilities are bundle: true and nothing else, the same family as Fathom (#720), Pulse and Statable. Privatus Analytics counts visitors from a daily salted hash of the connecting IP and user agent, so beacons routed through the Nuxt server would merge every visitor into one.

About bundling: the tracker reads its options from its own script element (document.currentScript). It posts to {data-api}/api/event and loads optional modules from {data-api}/js/pa.<name>.js, falling back to the origin it was served from. A bundled copy is served from the Nuxt origin, so the composable always pins data-api (default https://privatusstats.com). No SDK patch is needed. Only the main script is bundled. Optional modules still load from the API origin at runtime.

The tracker sets no cookies and keeps no visitor ID in the browser. The only thing it writes is the visitor's own opt-out flag in localStorage. It is about 3.5 KB gzipped. Client-side navigation is counted through history.pushState, so Vue Router page views need no setup.

Playground and fixtures use site: 'pa_test123', which is not a registered site, so the API drops its events. The tracker also sends nothing on localhost or when navigator.webdriver is set, so browser tests don't record visits.

Tests: unit (test/unit/privatus-analytics.test.ts for the script input, bundle.resolve and dev validation, plus proxy-configs), types, and an e2e fixture that checks the bundled script keeps data-site and data-api and that the tracker API is installed after load. pnpm lint (no new warnings), pnpm typecheck, the unit and typecheck projects, and the new e2e test pass locally. registry-types.json is regenerated. I didn't regenerate script-sizes.json. Happy to add it if you'd like it in this PR.

Walkthrough

The change adds Privatus Analytics to the script registry, with configuration validation, a runtime API, and bundle resolution. It marks the integration as unsupported for proxying. Documentation, a playground page, Nuxt fixtures, and tests cover its configuration, tracking API, bundle behaviour, and proxy exclusion.

Priority: Normal

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: Low · up to 62a1a

Guidance may lead to duplicate page views or missing engagement measurements, and one supported tracking call is rejected by TypeScript. These are bounded issues suitable for targeted follow-up.

## Page views in Nuxt

The tracker counts client-side navigation through `history.pushState`, so Vue Router page views need no setup. To send page views yourself, set `manual: true` and call `proxy.pageview()`{lang="ts"}.

Explain how to disable automatic SPA page views.

If a Nuxt app calls proxy.pageview() on each navigation, manual: true alone still lets the tracker count SPA navigations automatically. This guidance can therefore lead to duplicate page views. Tell users to set spa: 'off' as well when they manage every page view themselves. (privatusanalytics.com)

Accept the callback-only track call.

The tracker supports track('Logout', done), but this signature requires the second argument to be PrivatusAnalyticsProps. TypeScript therefore rejects a supported call. Add an overload for the callback-only form while retaining the properties form. (privatusanalytics.com)

Clarify that modules replaces the default.

If a user sets modules: ['auto'] to add automatic events, Line 1429 causes the composable to emit data-modules="auto". The tracker then disables its default engage module, so time-on-page and scroll-depth data stop. State that users must include 'engage' to keep those measurements. Update the matching documentation.
