Overview

Renders structured log records as a human-scannable timeline. Output format is intentionally compact:

HH:MM:SS.mmm I LEVEL COMPONENT LABEL                  k=v k=v

Colour is enabled when the target IO is a TTY (or when ‘color: true` is forced). Redaction is optional and injected as a dependency so callers can substitute a stricter `Browserctl::Redactor` or pass `nil` to disable.
