/*
 * ═══════════════════════════════════════════════════════════════════════════
 * UNIFIED MICRO AND BIGG FRAMEWORK
 * Integrating HDGL Analog Precision with Emergent Constant Resonance
 * ═══════════════════════════════════════════════════════════════════════════
 *
 * Unifies:
 * - HDGL Analog v30/v30b: Arbitrary precision, complex dynamics, RK4 evolution
 * - fudge10: Emergent constant fitting via D_n(r) symbolic operators
 * - bigG: Φ-recursive scaling for gravitational and cosmological constants
 * - physics.md: Unified field theory with Ω field tension
 * - Resonance excitation: Schumann harmonics and echo crescendo amplification
 *
 * Core Formula: D_n(r) = √(ϕ · F_n · 2^n · P_n · Ω) · r^k
 * Where:
 *   ϕ = 1.618... (Golden ratio)
 *   F_n = ϕ^n / √5 (Fibonacci scaling)
 *   P_n = product of first n primes
 *   Ω = domain-specific field tension
 *   r = radial coordinate
 *   k = dimensional exponent
 *
 * Physical Constants (Emergent Framework from physics.md):
 *   h  = √5 · Ω_h  · ϕ^{6(n+β)}  · b^{n+β}  [Planck constant]
 *   G  = √5 · Ω_G  · ϕ^{10(n+β)} · b^{n+β}  [Gravitational constant]
 *   k_B = √5 · Ω_kB · ϕ^{8(n+β)}  · b^{n+β}  [Boltzmann constant]
 *   m_u = √5 · Ω_mu · ϕ^{7(n+β)}  · b^{n+β}  [Atomic mass unit]
 *   c  = √(Ω_m) · ϕ^{6(n+β)} · b^{n+β}       [Speed of light]
 *
 * Resonance Modulation:
 *   All constants dynamically modulated by spectral power at Schumann frequencies
 *   Echo crescendo amplification at 7.83 Hz and harmonics
