Closes the long-open "export HTML roundtrip?" question as export-only — the
architecturally-correct, industry-aligned choice (TipTap/ProseMirror, Lexical,
Slate, Notion all keep JSON as the canonical lossless persistence format and
treat HTML/MD as projections).
- README "Serializacion e intercambio" doctrine: JSON = truth; HTML/MD =
export-only projections; import = JSON + plain text. Explains the
state-complete-HTML trap that JSON avoids, why markdown is the most lossy
(GFM cells are inline-only — block cells from P5m can't roundtrip), and the
conditional `parseHtml` per-block path (parseDOM/importDOM pattern) IF
paste-from-external is ever needed — as clipboard interop, never persistence.
- continue.md: the "NO firmada" note flipped to FIRMADA with the rationale.
Docs only.
