"""Unit: dashboard's detail-view line builder.

_detail_lines returns (text, attr) tuples. Most are plain; for
pipelock-block proposals it appends a "→ would allow host: <host>"
line tagged with the green attr so the operator sees at a glance
which hostname will land in pipelock's allowlist on approval."""
