   CONCEPT 1 — "BLUEPRINT"
   Light engineering document. Hairlines, mono spec labels, sharp 3px corners.
   Automotive dialect: technical drawing — dimension lines with tick ends,
   hex-bolt corner marks, tyre-tread hairline dividers, gauge tick rulers,
   one light-treated workshop photo band.
   Orange is a signal colour only: rules, ticks, bolts, icons, one badge.
