/* ============================================================
   Tony’s Hangar — Tony Jürgens, engineering portfolio · v3
   Plain CSS, no dependencies, no web fonts (system DIN-style
   condensed faces for signage: DIN Condensed on Apple devices,
   Bahnschrift on Windows, Roboto Condensed on Android).

   The theme is an aircraft hangar: sliding doors, floor
   markings, airfield signs, riveted data plates, a tool chest
   and a departures board. Kept legible first, themed second.
