/**
 * Phase 2 (legacy flat pages) normalization.
 *
 * Converts the loose `PdfDocumentPhase2` shape — pages with `text` /
 * `texts` / `graphics` arrays and a meta block — into a strict
 * `NormalizedPdfDocument` ready for `renderPdfPages`. Performs all
 * runtime validation that the Zod schema would catch in strict mode,
 * but throws structured `PdfError("SCHEMA_REJECTED")` errors carrying
 * the failing JSON path in `details.path`.
 *
 * Extracted from `engine.ts` during M3.b. No behavior changes.
