/* ==============================================================
   LEON CWIERTNIA — WERKSTATT
   A shop floor, not a brochure.

   Identity rules (locked — do not drift):
     · radius 0 everywhere. no soft shadows. no glassmorphism.
     · palette capped: graphite / painted white / safety yellow / oxide red.
       one LED green for "running". nothing else.
     · monospace is the dominant voice. sans is a supporting player.
     · display type is Archivo at extreme condensed width = painted signage.
     · structure stays exposed: hairlines, ticks, screws, part numbers.
     · motion is mechanical — steps(), not smooth fades.
     · texture is real (grain overlay). generated pages never have grain.
