The briefing email, rewritten

A decision letter instead of a score summary — MRR, churn, Domain Rating and organic, each figure labelled with the window it came from.

• New shape: Overview, Today, Live Pulse, Key metrics.
• Every figure says which window it covers, so a 7-day number is never read as a 30-day one.
• Send one briefing on demand without waiting for the next cron run.
