Website Fixes & Email Verification Setup

I have a small “Loveable” site that lives on GitHub Pages and I’m looking for a quick tidy-up:

• Set up account-verification emails: I haven’t chosen a provider yet, so I’ll need you to recommend and configure something lightweight (SendGrid, Mailgun, Amazon SES—open to the simplest option). The flow should trigger automatically after sign-up, send a confirm-your-email link, and mark the account as verified once the link is clicked.

• Track down and repair every broken link across the site so no visitor ever hits a 404 again.

The codebase is plain HTML/CSS/JavaScript in a GitHub repository; you’ll get branch access for your changes and can raise a pull request when you’re done. Deliverables are:

1. Working verification email system, documented in a short README snippet (API keys redacted).
2. Clean link map showing what was fixed, plus the updated pages pushed to the repo.

That’s it—straightforward, but I’d like it polished and merged promptly.
