Interview Prompt
A content `feed` arrives as a list whose entries are grouped into sub-lists nested to arbitrary depth; collapse it into a single flat list of leaf values in their original left-to-right order. A leaf is any non-list value, so a string stays whole rather than being split into its characters, and empty sub-lists contribute nothing.
Summary
Sections nested inside sections. One stream, in order.
