/* ==========================================================================
   Down To Groundworks — finished static build (leg 3)
   De-canvassed from the Claude Design return. System: NVIDIA spine resolved to
   DTG (charcoal + signal red), Saira Condensed / IBM Plex Sans / IBM Plex Mono.
   Angular 2px, zero shadows/gradients (bar hero legibility), hairline rules,
   dual-canvas (near-black chapters + paper-white body).
