/**
 * Parse PDF bytes into a {@link FlowDoc} (E-PDF EP5): reconstruct via the tagged
 * structure tree when present (EP3), else the layout heuristic (EP4), lifting
 * raster images back into reading order (EP6). Records losses for encryption that
 * could not be opened, heuristic (untagged) reconstruction, and the vector
 * regions that are not reconstructed (clipping paths, bare `sh` shadings).
 *
 * @param bytes    The complete PDF file bytes.
 * @param password The user password for an encrypted source; the empty string
 *                 opens permissions-only encryption.
 * @param filters  Decoders for `/Filter` names this reader does not implement
 *                 (§7.4); see {@link StreamFilters}.
 * @returns The reconstructed FlowDoc and its accumulated {@link Loss} report.
 *
 * Which of the two readings a file gets is the FILE's to decide and no
 * caller's: a page that is mostly marks is reproduced where it stands, one
 * that is mostly lines is re-set as a document, and the reader records which
 * it chose. There is no override — see the note on {@link readingOf}.
