/* Internet Chronicle — editorial record, two themes.
   Ported from the design canvas "Timeline Variants":
   light warm-paper timeline + dark warm-black reading pages, AUTO/LIGHT/DARK
   toggle, Spectral serif for display & prose, IBM Plex Mono for everything
   structural. Status colors carry meaning; oxblood/salmon is the only accent.
   Extensions not in the canvas (kept in the same idiom): the EN pending
   marker, LOW CONFIDENCE flag, ARCHIVED source links, update source links. */
