+## Stack

+- Next.js 15 (App Router) + React 19 + TypeScript
+- Tailwind CSS 4 (CSS-first config in `app/globals.css`)

+- lucide-react (icons)

+## Editing copy
+
+All user-facing copy lives in `content/`:
+
+| File | Purpose |
+| --- | --- |
+| `content/site.ts` | Site name, tagline, description, social URLs, brand asset URLs |
+| `content/products.ts` | Product cards: name, tagline, description, status, href |
+| `content/values.ts` | "Why SentrisCloud" value props |
+| `content/nav.ts` | Top nav and footer link grids |
+
+Editing copy never touches JSX — change the data, the section re-renders automatically.
+
+## Adding a section
+
+1. Create `components/sections/<name>.tsx`
+2. Export a function component
+3. Import in `app/page.tsx` and place it where you want
+4. If it has data, put data in `content/<name>.ts`
+
+## Live stats
+
+`components/sections/stats.tsx` is a server component that calls `getChainSnapshot()` (in `lib/chain.ts`) which queries the mainnet RPC. The whole page is revalidated every 60s (`export const revalidate = 60` in `app/page.tsx`) — keeps RPC traffic predictable.
+
+Override the RPC by setting `NEXT_PUBLIC_MAINNET_RPC` in `.env.local`.
+
+## Run
+
+From the monorepo root:
+
+```bash
+pnpm -F @sentriscloud/landing dev
+# → http://localhost:3000
+```
+
+Build:
+
+```bash
+pnpm -F @sentriscloud/landing build
+```
+
+## Deploy
+
+Vercel-ready: `Root Directory` = `apps/landing`, `Install Command` = `pnpm install`, `Build Command` = `pnpm build`. Set `NEXT_PUBLIC_MAINNET_RPC` if not using the default.
+
+## Design system
+
+Aesthetic follows `sentris-design`: editorial luxury (Playfair Display + Sora + IBM Plex Mono, emerald-on-canvas dark), no crypto-neon, no glassmorphism. Tokens defined in `app/globals.css` under `@theme`.
