   AETERIA — the design system. LAW. Every surface obeys.

   THE ONE-LINE LAW:
   Gray-dark ground. Amber light. Thin glass. Sharp particles as smoke.
   No blue. No clutter. 60fps. Senior-architect Apple grade.

   QUALITY GATES (checked by tests/visual QA):
   zero blue backgrounds · zero invisible text · every button answers ·
   1px glass edges · sharp particles · 60fps · no console errors ·
   every form accepts input · 4.5:1 contrast
