The bot's poller and the web viewer's preview each carried the same API timestamp parser, API item field extraction, RSS published-date parse, and the allow_private_urls / max_response_bytes / max_parsed_items config reads. modules/feed_parse.py now holds those; the default size limits move there and feed_manager re-exports them.
Where the two sides differ they still do: the bot skips non-dict and id-less API items while the preview turns string items into dicts, and the preview unwraps items/data/results from a bare dict response. Those divergences are a separate decision.
