Cold Three Three — Automation Studio Site

Marketing site for an n8n / automation freelance practice serving CPG founders and small operations teams. Built with Next.js 16, Tailwind v4, and Sanity (CMS).

Stack

• Next.js 16 — App Router, Server Components, ISR with tag revalidation
• Tailwind CSS v4 — design tokens via @theme
• Sanity CMS v5 — content managed at /studio (embedded)
• Vercel — deployment + env vars

Local development

npm install
cp .env.example .env.local   # then fill in real values
npm run dev

Then open http://localhost:3000. The CMS lives at http://localhost:3000/studio.

How content updates flow

1. Edit a project in Sanity Studio (/studio)
2. Sanity calls POST /api/revalidate?secret=… (configured as a webhook)
3. The route handler calls revalidateTag("projects", { expire: 0 })
4. The next visit to the homepage rebuilds the showcase from fresh data

No full Vercel redeploy is required for content changes.

First-time setup

See SETUP.md for the step-by-step walkthrough (creating a Sanity account, setting Vercel env vars, configuring the webhook).
