-- quantum-resources.lua
-- Sovereign Trinity Kernel — LuaJIT/LuaLaTeX nexus layer.
--
-- Pipeline:
--   ANU QRNG (vacuum fluctuations) → 6502 VM (MoA orchestrator)
--   → Dex FFI (verified GF2 kernels) → LaTeX macros → PDF
--
-- Every number in the paper is computed, not typed.
-- The entropy comes from real quantum physics in Australia.
-- The math is verified by Dex shape-safe kernels.
-- The proofs are closed by Lean 4 (zero sorry).
