 ## Enforceable boundaries
 
 - Code style и i18n: [`docs/CONVENTIONS.md`](docs/CONVENTIONS.md), исполняются Biome и TypeScript.
+- React component declaration, props и export style: [`docs/CONVENTIONS.md`](docs/CONVENTIONS.md), часть исполняется Biome, часть является mandatory review convention.
 - FSD и public API: [`docs/STRUCTURE.md`](docs/STRUCTURE.md), исполняются dependency-cruiser и Knip; направление `app → pages → features → entities → shared`.
 - HTTP и types: [`docs/API-LAYER.md`](docs/API-LAYER.md); только typed client и generated OpenAPI `paths[...]`, без ручных transport DTO и прямых T-Bank calls.
 - UI states и VM/view boundary: [`docs/UI-PATTERN.md`](docs/UI-PATTERN.md); container вызывает page VM hook, VM владеет data/state/derived presentation data, `*.view.tsx` получает props и рендерит. View files дробить по semantic responsibility, когда section/state можно назвать отдельно.

+## React component style
+
+Biome-enforced guardrails:
+
+- Named React components объявлять как const-valued components, а не function declarations.
+- Не использовать default exports.
+- Export statements держать после declarations тела module.
+
+Mandatory review conventions:
+
+- React components типизировать через `FC`: `const Component: FC<Props> = (props) => { ... }`; если props нет — `const Component: FC = () => { ... }`.
+- Props описывать named type рядом с component либо в `Component.types.ts`, если type переиспользуется или file становится крупным.
+- Не использовать inline props typing в component parameters.
+- Для components только с `children` использовать `FC<PropsWithChildren>` без отдельного props alias. Если кроме `children` есть другие props, использовать named props type на основе `PropsWithChildren<{ ... }>`.
+- Не destructure props в component parameters; принимать `props` и destructure внутри component body.
+- Обычный module export surface сводить к одному нижнему named export block, когда это выражается читаемо без потери public API.
+- Чистые barrel files должны использовать прямой re-export без промежуточного import: `export { Component } from "./Component";`.
+
 ## File roles
 
 - `Component.tsx` - контейнер или публичный компонент; для data-driven pages вызывает page VM hook и выбирает top-level state view.
