Live HTML recon discovered stable BEM-style classes. Each history item is a
.OffersArchiveSearchOffers__row with 6 positional cells: area+rooms, floor,
start_price+ppm2, last_price+ppm2, publish_date+exposure, status/removed_date.
Drops chunked-text fallback as primary strategy (kept as last-resort with
warning log). Eliminates 3 PRs of regex whack-a-mole (#538/#541/#542):
- area = year+area concat → impossible with cell isolation
- area = sub-fragment '2,2' → impossible
- date inversion → cell [4] is always publish, cell [5] is always removed
- 1-комн/2-комн/3-комн all parsed identically
Re-sweep Базовый 52 should now hit ~90%+ plausible area_filled vs 8.7%
from PR #542.
