+# @mintel/observability
+
+Standardized observability package for the Mintel ecosystem, providing Umami analytics and Sentry/GlitchTip error tracking with a focus on privacy and ad-blocker resilience.
+
+## Features
+
+- **Umami Smart Proxy**: Track analytics without external scripts and hide your Website ID.
+- **Sentry Relay**: Bypass ad-blockers for error tracking by relaying envelopes through your own server.
+- **Unified API**: consistent interface for tracking across multiple projects.
+
+## Installation
+
+```bash
+pnpm add @mintel/observability @sentry/nextjs
+```
+
+## Usage
+
+### 1. Unified Environment (via @mintel/next-utils)
+
+Define the following environment variables:
+
+```bash
+# Analytics
+UMAMI_WEBSITE_ID=your-website-id
+UMAMI_API_ENDPOINT=https://analytics.infra.mintel.me
+
+# Error Tracking
+SENTRY_DSN=your-sentry-dsn
+```
+
+Note: No `NEXT_PUBLIC_` prefix is required for these anymore, as they are handled by server-side proxies.
+
+### 2. Analytics Setup
+
+In your root layout:
+
+```tsx
+import {
+  AnalyticsContextProvider,
+  AnalyticsAutoTracker,
+  UmamiAnalyticsService,
+} from "@mintel/observability";
+
+const analytics = new UmamiAnalyticsService({
+  enabled: true,
+  websiteId: process.env.UMAMI_WEBSITE_ID, // Server-side
+  apiEndpoint:
+    typeof window === "undefined" ? process.env.UMAMI_API_ENDPOINT : "/stats",
+});
+
+export default function Layout({ children }) {
+  return (
+    <AnalyticsContextProvider service={analytics}>
+      <AnalyticsAutoTracker />
+      {children}
+    </AnalyticsContextProvider>
+  );
+}
+```
+
+### 3. Route Handlers
+
+Create a proxy for Umami:
+`app/stats/api/send/route.ts`
+
+```ts
+import { createUmamiProxyHandler } from "@mintel/observability";
+export const POST = await createUmamiProxyHandler({
+  websiteId: process.env.UMAMI_WEBSITE_ID,
+  apiEndpoint: process.env.UMAMI_API_ENDPOINT,
+});
+```
+
+Create a relay for Sentry:
+`app/errors/api/relay/route.ts`
+
+```ts
+import { createSentryRelayHandler } from "@mintel/observability";
+export const POST = await createSentryRelayHandler({
+  dsn: process.env.SENTRY_DSN,
+});
+```
+
+### 4. Notification Setup (Server-side)
+
+```ts
+import { GotifyNotificationService } from "@mintel/observability";
+
+const notifications = new GotifyNotificationService({
+  enabled: true,
+  url: process.env.GOTIFY_URL,
+  token: process.env.GOTIFY_TOKEN,
+});
+
+await notifications.notify({
+  title: "Lead Capture",
+  message: "New contact form submission",
+  priority: 5,
+});
+```
+
+### 5. Sentry Configuration
+
+Use `initSentry` in your `sentry.server.config.ts` and `sentry.client.config.ts`.
+
+On the client, use the tunnel:
+
+```ts
+initSentry({
+  dsn: "https://public@errors.infra.mintel.me/1", // Placeholder
+  tunnel: "/errors/api/relay",
+});
+```
+
+## Architecture
+
+This package implements the **Smart Proxy** pattern:
+
+- The client NEVER knows the real `UMAMI_WEBSITE_ID`.
+- Tracking events are sent to your own domain (`/stats/api/send`).
+- Your server injects the secret ID and forwards to Umami.
+- This bypasses ad-blockers and keeps your configuration secure.
