Both Ghost CMS subscription page and Paymenter billing are fully
configured and live in production. Updated audit to reflect:

GHOST CMS (firefrostgaming.com):
- Live subscription page with Fire/Frost dual-path branding
- 11 subscription tiers displayed
- Production-ready design

PAYMENTER (billing.firefrostgaming.com):
- 11 subscription tiers fully configured
- The Awakened $1, Elemental $5, Knight $10, Master $15, Legend $20, Sovereign $499
- Fire/Frost path variants for each tier
- Order Now buttons functional

These were completed but not documented in the infrastructure audit.
