Framer Header Currency Switcher

I need a lightweight dropdown embedded in the site header that lets visitors toggle between INR, USD. The moment a new currency is chosen, every price on the Framer-built frontend must refresh to that denomination and stay consistent as the user browses, using session or localStorage to remember the preference.

Styling has to feel completely native: match our colour scheme, keep the exact font and sizing, and follow the button treatment already in the header. No paid Shopify apps, no back-end edits—this is strictly a front-end enhancement that talks to the existing Shopify data without touching its configuration.

Deliverables
• Responsive dropdown component placed in the header
• Client-side script that converts and displays prices site-wide in real time
• Persistence of the selected currency across all pages
• Clean, well-commented code packaged for quick hand-off

It’s an urgent, low-complexity job, so the ability to start immediately and deliver fast is essential. Please let me know your turnaround time and any examples of similar Framer + Shopify work you’ve done.
