Local adaptations are the tool interface, file/page/size limits, deterministic flat filenames,
page selection, lifecycle cleanup, a resource-free Markdown renderer, and strict sanitized
preview/export. No upstream brands, example documents, images, songs or analytics included.
The website CSP is unchanged. The downloadable offline HTML has its own restrictive CSP:
no script, automatic image/frame/network loads, forms or base URL; only the site's fixed
inline typography stylesheet is permitted. Plain Markdown export retains the user's source.
