/**
 * Normalizes a flat replacement string into paragraph blocks for span targets.
 *
 * Rules (per D3):
 * 1. Normalize line endings (\r\n and \r → \n).
 * 2. Split paragraph boundaries on \n\n+ (two or more consecutive newlines).
 * 3. Trim leading/trailing empty chunks after split.
 * 4. Each separator run (\n\n, \n\n\n, etc.) creates one boundary (no implicit empty paragraphs).
 * 5. If normalized output has zero blocks, fail with INVALID_INPUT.
 * 6. Single \n within a chunk remains as inline line break content.
