;;; Commentary:
;; Unit tests for `cj/music--m3u-entries': parse .m3u text into an alist of
;; (stream-url . plist), each plist carrying :name (the #EXTINF label), :uuid
;; (#RADIOBROWSERUUID), and :favicon (#RADIOBROWSERFAVICON).  This is the one
;; pure parser both the name resolution (Phase 1) and the cover-art layer read.
