Context

We want aggregate usage numbers to know what's worth building next, without tracking individuals. Use Plausible or self-hosted Umami.

Acceptance criteria

• Script added only after cookie-free consent check
• Tracks: pageviews, sign-ups, directory searches, RSVPs, job posts
• No PII, no cross-site tracking, no fingerprinting
• Documented in /privacy

Depends on #27.
