   One shared magazine skeleton, three path skins. The renderer stamps
   body[data-path] from the manifest path id (see _stamp_path_attr), and every
   rule below keys off that attribute, so an accent only ever lands on the
   guide's own path. shared/magazine.css stays frozen: this layer only overrides
   its colours plus one new hero dot, and shifts figure / pull-quote alignment.
   All tints are light-theme; no path changes the page grid or the reading
   measure.
