- Preserve leading whitespace in text_with_formatting() to fix ~80% of
missing-space issues (e.g. "holdermeans" -> "holder means")
- Tighten word boundary gap threshold from 0.05 to 0.01 and add
word-count heuristic to distinguish CID word-level operators from
Type1 line-level operators, fixing spurious spaces (e.g. "t emporary")
- Replace fixed paragraph threshold (1.8x base_size) with dynamic
median-based computation for double-spaced documents
- Remove --- page break markers between pages
- Fix page number y-threshold for US Letter (720pt vs 800pt)
Eval: +1.4% mean word_sim, zero char_sim regressions across 63 PDFs.
