Review follow-ups:
- The phrase's median counts each word once: neighbouring words OCR
sized alike share a run, so 15, 9 and 9 pt gave 12 pt, not 9.
- The styled rewrite's width calibration is not clamped again after the
phrase ratio, so a word sized at more than twice the phrase keeps the
width the scan shows it at.
- The single-style rewrite (a new family or bold) scales the first
word's Tz by its own size over the phrase's, so the line is as wide
whatever size OCR guessed for that word.
