// Pasted email content (signatures, replies, quoted text) commonly carries
// inline styles on block elements. StarterKit's default Paragraph/Heading
// drop unknown attributes; the composer extends them with these so `style`,
// `class` and the signature range marker round-trip the editor. Kept in its
// own module so tests can build the exact composer paragraph instead of
// hand-copying (and silently drifting from) this config.
