Why this matters
Markdown renders differently across platforms. A README that looks clean in GitHub may have broken heading hierarchy in a CMS, collapsed code blocks in Notion, or malformed tables when pasted into Confluence. A local previewer lets you verify structure, table formatting, and link rendering before committing or publishing. It is especially useful when writing documentation that will be rendered somewhere you cannot easily preview in real time, or when the output will be converted to another format downstream.
