   Triple Layer Engineering — design tokens
   Concept: technical-drawing / spec-sheet. Navy blueprint ground, warm paper
   panels, a single gauge-amber accent. Corner registration marks and hairline
   rules stand in for the numbering a stepped process would use — this content
   is categorical, not sequential, so no 01/02/03 markers anywhere.
