/* ===========================================================
   DRYER VENT UNIVERSITY — DESIGN SYSTEM
   Concept: the "Field Tag" — every card, badge and photo slot
   borrows the shape of an inspection tag clipped to a duct run:
   die-cut corner, grommet hole, mono-set stamp label. Typography
   pairs an industrial condensed display face (signage authority)
   with IBM Plex Sans/Mono (documentation, evidence, case files).
