Reason for Selling

I built Sidus Astro end-to-end as a complete production product and I'm moving on to new projects. Rather than leave it idle, I want it acquired by someone who can market and grow it in the spirituality and wellness space. The codebase, domain, Stripe integration, and documentation are ready for immediate handover.
