 - **ky v2**: Uses `baseUrl` + `prefix` (not `prefixUrl`). Hooks receive a single state object (`{ request }`, `{ response }`) instead of positional arguments.
 - **TypeScript 6**: Requires `"ignoreDeprecations": "6.0"` in tsconfig when using `baseUrl` + `paths` for `@/*` aliases.
 - **Tailwind v4**: Uses `@import "tailwindcss"` and `@theme inline` block (not `@tailwind base/components/utilities`).
+- **Zod v4**: Import from `zod/v4` (not `zod`). Use `@hookform/resolvers/zod` for form resolver.
+- **TypeScript `verbatimModuleSyntax`**: All type-only imports must use `import type` syntax. Common: `ColumnDef` from TanStack Table, `UseFormRegister` from react-hook-form, `z.infer` results.
+- **react-hook-form sub-components**: `UseFormRegister<A>` is not assignable to `UseFormRegister<B>` even when A extends B (contravariance). Prefer inlining fields or passing individual `register("field")` results as props.
