// Shared redirect tables consumed by both `next.config.ts` (the Next.js
// build) and `vercel.ts` (the TanStack/Vercel deploy). Defined once here
// so the two configs don't drift.
//
// Shape mirrors Next's `redirects()` entry and Vercel's `Redirect` type
// (they're identical — `source`, `destination`, `permanent`, optional
// `has`). Basepath handling differs between the two: Next auto-prefixes,
// Vercel doesn't — each consumer is responsible for that.
