The React components page now explains which components render only in the browser, and a new help center article covers components that flash or are missing from the page source.
The new article is added to the Help center group in each language's navigation.
Based on Update from support feedback: clarify custom components are client-rendered, which added the English content.

Overview
Adds Spanish, French, and Chinese versions of the guidance that custom React components are client-rendered only, mirroring the English update from support feedback.

Each locale’s customize/react-components page now spells out which patterns are browser-only (export in MDX, named imports from .jsx snippets) versus server-rendered (MDX snippets imported as content), and expands SEO and initial load notes (flash, layout shift) with pointers to built-in components.

A new help center article explains why custom components can flash or be missing from “view source,” when to use built-in components instead, and is wired into es.json, fr.json, and zh.json Help center navigation.
