Can you fix it without breaking my live store?

Yes. We work on a staging copy, ship the minimal correct fix rather than a sweeping refactor, add a regression check so the bug can’t silently come back, and clear only the caches that need clearing. You get to review the change on staging and sign off before anything reaches production. Because Hyvä is a transparent Tailwind + Alpine stack, fixes are usually small and surgical, not risky theme-wide rewrites.
