Bilingual EN/JA Next.js + Sanity

Bilingual EN/JA Next.js + Sanity Website for a Casting Studio Portfolio demo: a bilingual English/Japanese website for a fictional casting studio, built with Next.js (App Router, TypeScript) and Sanity CMS, deployed on Vercel. English at the root with a full Japanese mirror, a language switch that keeps you on the same page, and hreflang plus JSON-LD on every page. Lighthouse mobile 92-99, CLS 0, first-load JS under 150 KB, all checked in CI. WCAG 2.2 AA, tested with Playwright and axe. The contact form posts signed JSON to a CRM with retries, a queue and an email fallback, so an outage never loses an enquiry.
