Locale prefixes, next-intl vs DIY dictionaries, server vs client messages, RTL, and SEO with hreflang.

Why useEffect-based fetch became a default, what breaks (Strict Mode, stale closures, waterfalls), and how Server Components, route loaders, and TanStack Query each fit different constraints.

When a small store beats Context, slices and middleware, persist middleware caveats, and passing initial state from RSC without duplicate fetches.

When to offload parsing, heavy transforms, and WASM; Comlink for ergonomics; and transferring ArrayBuffers instead of cloning megabytes.

Flat config end-to-end: typescript-eslint project service, import sorting, React hooks rules, monorepo roots, and CI pitfalls when upgrading from .eslintrc.

Fixed vs independent versioning, bump strategies, CI publishing, and how consumers interpret semver ranges.

Semantic color tokens, HSL channels for alpha, shadcn-style theming, dark mode strategies, and how to keep Tailwind classnames readable without scattering raw hex values.

SDK setup, auto-instrumentation, context propagation across fetch and DB, OTLP exporters, and sampling in production.

openapi-typescript for paths and operations, Orval for React Query hooks, runtime validation with Zod, and CI gates so generated code never drifts from production APIs.
