+Your style is inspired by Cleo Abram's "Huge If True" — you make complex technical topics feel exciting, accessible, and important. Key principles:
+- Start with a BOLD claim or surprising fact that makes people stop scrolling
+- Use analogies and real-world comparisons to explain technical concepts
+- Build tension: "Here's the problem... here's why it matters... here's the breakthrough"
+- Keep energy HIGH — short sentences, active voice, conversational tone
+- End with a clear takeaway that makes the viewer feel smarter
+- Target audience: developers who want to stay current but don't have time to read everything
+
+Script format: 60-90 second explainer videos. Think TikTok/YouTube Shorts energy with real educational depth.

+# Umami Analytics Setup
+
+## Overview
+Umami is self-hosted on Vercel + Supabase for $0/month analytics.
+
+## Setup Steps
+
+### 1. Fork Umami
+Fork https://github.com/umami-is/umami to the CodingCatDev GitHub org.
+
+### 2. Create Umami tables in Supabase
+Run the Umami PostgreSQL schema in your Supabase SQL editor.
+See: https://umami.is/docs/install
+
+### 3. Deploy to Vercel
+- Import the forked repo in Vercel
+- Set environment variable: `DATABASE_URL` = your Supabase connection string
+- Deploy
+
+### 4. Configure
+- Visit your Umami instance (e.g., analytics.codingcat.dev)
+- Create a website entry for codingcat.dev
+- Copy the Website ID
+
+### 5. Set environment variables in codingcat.dev
+```
+NEXT_PUBLIC_UMAMI_WEBSITE_ID=<your-website-id>
+NEXT_PUBLIC_UMAMI_URL=https://analytics.codingcat.dev/script.js
+```
+
+### 6. Custom domain (optional)
+Add `analytics.codingcat.dev` as a custom domain in Vercel for the Umami project.
+
+## Querying Analytics Data
+Since Umami writes to your Supabase database, you can query analytics directly:
+
+```sql
+-- Top pages last 30 days
+SELECT url_path, COUNT(*) as views
+FROM website_event
+WHERE website_id = '<your-id>'
+  AND created_at > NOW() - INTERVAL '30 days'
+  AND event_type = 1
+GROUP BY url_path
+ORDER BY views DESC
+LIMIT 20;
+
+-- Sponsor report: views by content type
+SELECT 
+  CASE 
+    WHEN url_path LIKE '/post/%' THEN 'Blog Post'
+    WHEN url_path LIKE '/podcast/%' THEN 'Podcast'
+    WHEN url_path LIKE '/course/%' THEN 'Course'
+    ELSE 'Other'
+  END as content_type,
+  COUNT(*) as views,
+  COUNT(DISTINCT session_id) as unique_visitors
+FROM website_event
+WHERE website_id = '<your-id>'
+  AND created_at > NOW() - INTERVAL '30 days'
+  AND event_type = 1
+GROUP BY content_type
+ORDER BY views DESC;
+```
