Timeline: Q4 2025
Priority: Medium
Estimated Effort: 2-3 days

Description: Add SRI hashes to all external resources (Google Fonts) to prevent supply chain attacks.

Implementation:

<!-- Current (without SRI) -->
<link href="https://fonts.googleapis.com/css2?family=Inter:wght@400;500;600;700&family=Orbitron:wght@400;500;600;700&family=Share+Tech+Mono&display=swap" 
      rel="stylesheet">

<!-- Future (with SRI) -->
<link href="https://fonts.googleapis.com/css2?family=Inter:wght@400;500;600;700&family=Orbitron:wght@400;500;600;700&family=Share+Tech+Mono&display=swap"
      rel="stylesheet"
      integrity="sha384-GENERATED_HASH_HERE"
      crossorigin="anonymous">

Automation Script:

#!/bin/bash
# Generate SRI hashes for external resources
for url in $(grep -oP 'https://[^"]+' index.html | grep -E '(googleapis|gstatic)'); do
    hash=$(curl -s "$url" | openssl dgst -sha384 -binary | openssl base64 -A)
