Sobre los archivos MDComparativa de ventajas

Limitaciones
HTMLZ Limitaciones
- Niche — no reader support.
- Not a mainstream delivery format.
- Calibre-only.
MD Limitaciones
- No formal authoritative spec — CommonMark, GFM, and MultiMarkdown differ on edge cases.

- Links to images stay external — no embedded media unless you base64-inline.
- Styling is limited to what HTML allows — custom branding requires CSS outside Markdown.
