/* ==========================================================================
   CueForge Labs — Forge Field Manual
   Shared product-dossier system. Loaded by every individual product route,
   by business-solutions.html and by the two Business Solutions app pages.

   Direction: a well-made technical field manual. Bold chapter markers, large
   evidence plates, annotated interface details, confident breathing room —
   on CueForge's near-black cinematic field with restrained circuit energy.

   Typography contract:
