/* Jenko jenko3 (FR) — from v19 « Schéma ». The page is a single-line diagram: a graphite cable duct runs down the left edge and carries
   the conductor; every block is a feeder with its own breaker. Yellow is the current: it lives on graphite only (the duct,
   the graphite bands) and, on light grounds, only as filled shapes with graphite letters. */
