Force HTTPS and add browser-level defenses - shippingszn launch readiness

HTTPS is the little padlock in the browser bar. It encrypts everything between your user and your server, so people sharing the same WiFi can't read passwords as they're being typed. Security headers are extra instructions you send to the browser saying “never trust content claiming to be from me unless it really is.”

Without HTTPS, anyone on the same coffee-shop WiFi can read your users' passwords as plaintext. Without security headers, attackers can wrap your site inside theirs (clickjacking) or trick browsers into running malicious scripts. The fixes are basically free.

The shippingszn CLI includes automated checks for this launch-readiness control.

The Launch Fix Kit keeps scan-specific findings, file and line evidence, AI-builder punch-list tasks, and verification steps tied to the paid report.

Most modern hosting (Replit, Vercel, Netlify, Cloudflare Pages, Railway) gives you HTTPS automatically when you publish — confirm the lock icon shows up in the browser bar.
Set up an automatic redirect from http:// to https:// so no one accidentally lands on the unencrypted version.
Add a Content-Security-Policy header that locks down where your scripts, images, and fonts are allowed to come from.
Add X-Content-Type-Options: nosniff and X-Frame-Options: DENY (or SAMEORIGIN if you embed your own pages).
Test your site at https://securityheaders.com — aim for at least an A grade.
