v2.1.0 - 5G NR Support, Unified Risk Assessment & UI Polish

What's New

5G NR FR1 Support

• 14 NR bands added: n1, n2, n3, n5, n7, n25, n28, n38, n41, n66, n71, n77, n78, n79 (3GPP TS 38.101-1)
• Total band count now 85 across 14 technology categories
• Full NR support in power estimation, duty cycle calculation, and receiver sensitivity

Unified Risk Assessment

• New calculate_unified_risk() bridges frequency-based and power-based analysis into a single consistent result
• Quantitative power data now upgrades frequency-only risk scores when available

Monte Carlo Simulation Fixed

• New monte_carlo_interference_analysis_multi() wrapper correctly connects the UI to the analysis engine
• Previous version had parameter name mismatches causing silent failures

New Features

• Coupling factor exposed as user-configurable slider (0.0-1.0) with Monte Carlo variation
• Bandwidth normalization in regulatory compliance checking
• 34 isolation matrix pairs (was 16) - added NR-WiFi, NR-GNSS, and cross-technology coexistence scenarios
• constants.py module as single source of truth for version, colors, risk styles, and sort orders

Professional UI Polish

• Removed ~80 emoji from all headers, buttons, expanders, and sidebar elements
• Streamlined sidebar layout with redundant status indicators removed
• Simplified chart legends (removed verbose mathematical formulas)
• Consolidated 4-column footer into single professional caption
• Unified color system across all charts via centralized constants
• New .streamlit/config.toml with professional blue theme

Bug Fixes

• Fixed Monte Carlo parameter name mismatch between UI and analysis engine
• Fixed disconnected analysis paths (frequency and power results now integrated)

v2.0.0 - Professional UI Overhaul

🎉 v2.0.0 - Professional UI Overhaul

Major Features

• 📋 Professional Results Table: Displays P_TX (dBm), P_RX (dBm), Desense (dB), Margin (dB), and 3GPP Compliance for every interference product
• 📊 Summary Dashboard: At-a-glance severity counts (Critical/High/Medium/Low/Safe) with compliance metrics
• 🔬 3GPP Compliance Report: Expandable violation report with regulatory references and critical isolation requirements
• ⚡ Monte Carlo Analysis: Optional worst-case analysis with P50/P95/P99 percentiles

New Modules

• regulatory_limits.py: 3GPP TS 36.101/38.101 spurious emission database with GPS L1 protection limits
• isolation_matrix.py: Per-band isolation requirements (20+ critical band pairs)

Code Quality Fixes

• Fixed legacy IM3 formula: 2×P_in - IIP3 → 3×P_in - 2×IIP3
• Removed duplicate path loss function
• Added edge case guards (empty list, division by zero, log10)
• Renamed IM3_Type → Product_Subtype for clearer terminology
• Fixed RFID/NFC zero-width bands (now 0.12 MHz bandwidth)
• Fixed broken emoji characters throughout
• Updated documentation references

Additional Assets
