Sobre os arquivos EPUBTOML Config

Sobre os arquivos TOMLComparativo de vantagens
EPUB Vantagens
- Open standard — no vendor lock-in, no DRM required.
- Reflowable text — adapts to any screen size, font size, or orientation.
- Rich typography via CSS, embedded fonts, and SVG.
- Accessibility-first: native support for screen readers, adjustable text, and alt-text.
- Universal across every non-Kindle ebook reader and library app.
TOML Vantagens
- Unambiguous parsing — every TOML 1.0 parser produces the same output.
- Native date/time types (unlike JSON).
- Comments, multi-line strings, nested tables.
- Explicit types with no coercion gotchas.
- Chosen by Rust (Cargo), Python (pyproject), Hugo, Zola.
Limitações
EPUB Limitações
- Kindle does not support EPUB natively (Amazon wants you to convert to AZW3).
- Fixed-layout EPUBs (for children's books, comics) are awkward to author.
- Rendering quality varies between apps — some CSS works everywhere, some does not.
- Adobe DRM (ADEPT) or Apple FairPlay are optional layers that complicate portability.
TOML Limitações
- Less flexible than YAML for deeply nested config.
- Table arrays with many rows become visually busy.
- Smaller ecosystem than YAML or JSON.
- Not ubiquitous in DevOps — tooling leans YAML.
