+# Zettai Systems website
+
+Static marketing site for **Zettai Systems** — IT services, solutions, and company pages.
+
+## Run locally
+
+Use the rewrite-aware server so clean URLs work (same as production):
+
+```bash
+python3 serve.py
+```
+
+Then open **http://127.0.0.1:8080/about** — not `file://…/about`.
+
+Optional port: `python3 serve.py 3000`
+
+`file://` cannot apply URL rewrites. Always use `serve.py` for local testing of `/about`, `/services/...`, etc.
+
+## Deploy to cPanel
+
+1. Upload **all** project files to your web root (usually `public_html`), preserving the folder structure (`css/`, `js/`, `assets/`, `services/`, etc.).
+2. Ensure `.htaccess` and `404.html` are in the web root (Apache `mod_rewrite` required for clean URLs).
+3. Confirm the site loads over HTTPS once your host certificate is active.
+4. Production URLs are extensionless (e.g. `/about`, `/services/cloud-integration`). Old `.html` URLs 301-redirect to the clean form.
+
+**Note:** `python -m http.server` does not apply `.htaccess`. For local clean-URL testing, use Apache or another server with rewrite support; opening `/about.html` still works as a static file.
+
+## Google Analytics
+
+GA4 is loaded from `js/analytics.js` on every page. Set `MEASUREMENT_ID` in that file to your `G-` stream ID (Admin → Data streams). Localhost traffic is ignored so preview does not pollute reports.
+
+## Theme toggle
+
+Light/dark preference is stored in `localStorage` under the key **`zs-theme`**.
+
+## Contact details
+
+- **Phone:** +91 807 299 8024 (`tel:+918072998024`)
+- **Email:** solutions@zettaisystems.com (`mailto:solutions@zettaisystems.com`)
+- **Careers email:** careers@zettaisystems.com
+- **Address:** No.10/21, 27th Street, Thillai Ganga Nagar, Nanganallur, Chennai – 600061, Tamil Nadu, India
+
+## Forms / email
+
+Contact and careers forms POST to PHP endpoints (requires PHP on the host, e.g. cPanel):
+
+- `/api/contact.php` → `solutions@zettaisystems.com`
+- `/api/careers.php` → `careers@zettaisystems.com` (resume attachment supported)
+
+Local `python3 serve.py` does **not** run PHP. Test mail on the live Apache/cPanel server after deploying the `api/` folder.
+
+Ensure mailboxes `solutions@` and `careers@` exist, and that PHP `mail()` (or hosting SMTP) is enabled.
+
+**Hosting note:** some hosts use a bot cookie (`humans_XXXX`) that returns HTTP 409 on first `/api/*.php` hits. The site JS sets that cookie and retries automatically. If mail still fails, whitelist `/api/` in ModSecurity / Imunify.

+## Notes
+
+- Official domain: **`https://zettaisystems.com/`** (canonical, sitemap, and og:url use extensionless paths).
+- Clean URLs require Apache rewrite via `.htaccess` after deploy.
