## What It Does Reads platform analytics data from `~/Documents/aireadylife/vault/brand/00_current/` where monthly metric snapshots are stored per platform. For each configured platform (LinkedIn, Twitter/X, YouTube, newsletter/Beehiiv, personal site via Google Analytics), extracts the current month's key metrics: follower or subscriber count, total impressions for the period, total engagements (likes, comments, shares, clicks), and calculates an engagement rate (engagements divided by impressions, expressed as a percentage). Compares each metric to the prior month's figures — both absolute change and percentage change — to produce MoM growth indicators. Growth direction is shown as ▲ (up), ▼ (down), or → (flat, within ±2%). Benchmarks the calculated engagement rate against platform-specific standards: LinkedIn 2-5% is good; Instagram 1-5%; Twitter/X 0.5-1%; newsletter 30-40% open rate, 2-5% CTR.

Formats the complete result as a structured summary table with one row per platform, metric columns for this month and prior month, delta indicators, and engagement rate vs benchmark. Flags any platform where engagement rate has dropped more than 20% MoM as 🟡 watch. Returns the formatted
