@Generated public final class EpubMetadata extends com.google.protobuf.GeneratedMessage implements EpubMetadataOrBuilder
 Comprehensive EPUB metadata as extracted by Tika from EPUB documents.
 Based on Tika's Epub interface, EpubParser, OPFParser implementations, and actual EPUB structure.
 This is a 1:1 mapping to all fields that Tika can extract from EPUB documents.
 EPUB files are structured ZIP archives containing:
 - META-INF/container.xml (points to OPF file)
 - *.opf file (package document with metadata and manifest)
 - XHTML content files (actual book content)
 - CSS, images, fonts (embedded resources)
 - Optional: metadata.xml (additional Dublin Core)
Protobuf type ai.pipestream.parsed.data.epub.v1.EpubMetadata
