Module marked_block 

Functions

contains_marker_line

True when content carries marker as a whole (trimmed) line — the only form the writers emit. Use instead of content.contains(marker) wherever “this file has the block” is meant.

remove_content

remove_from_file

replace_marked_block

Replace the region between start and end markers with replacement (trim-aware newlines). If markers are missing or invalid, returns content unchanged.
