Add Subscription Billing Integration

I run a small website that is built entirely with custom HTML + CSS and I’m now ready to accept paid members. The job is straightforward: introduce a subscription system that lets visitors choose between a Monthly or Annual plan and pay only by credit or debit card. Because there’s no back-end framework in place, I’ll need you to wire the existing static pages to a reliable card processor—Stripe or a comparable PCI-compliant gateway—so payments, renewals, and cancels are handled automatically. I’d also like lightweight authentication so active subscribers can reach a protected area that is already designed but not yet gated. Key deliverables: • Responsive pricing section showing both plans with dynamic “Subscribe” buttons • Secure checkout modal or page linked to the processor (credit/debit card only) • Webhook or equivalent logic to set, verify, and revoke access on payment events • Clear, commented HTML/CSS/JS edits so I can maintain them later No design overhaul is necessary—just cleanly integrated code that blends with the current look and keeps page speed snappy. If you’ve done Stripe, Razorpay, or similar integrations in static sites before, you’ll finish this quickly. Let me know your expected timeline and the gateway you’d recommend.
