A new "Subscribe" widget on the public Updates page lets visitors drop their email and get notified when you ship something new.

Under the hood:

• A changelog_subscribers table per project, with an unsubscribe token per row
• Anonymous-friendly: subscribers don't need a Hollahoop account
• One-click unsubscribe at /unsubscribe/<token> — no login required
• Subscriber count surfaced in Settings → Changelog so authors know the audience size before they publish

Email delivery hooks into the existing branded email setup; the system is in place, expect notifications to start sending on publish in the next pass.
