   LEHMANN AVIATION — specialized unmanned aircraft
   Design tokens — inherited from the X-1 system (Manrope + JetBrains Mono,
   Tesla-style full-viewport panels, 4px buttons, mono micro-labels), shifted
   to an industrial register: ink-dominant instead of white-dominant, and a
   single range-orange signal instead of the X-1 blue.
   Signature element: the MISSION TRACE — a hairline flight profile
   (launch / climb / profile / recovery) used as section divider and as the
   structural motif of the target pages.
