SwiftUI client for a self-hosted RSS news-correlation platform: signal feed,
story detail, article reader, feed manager, and LAN⇄Tailscale connectivity.
Project generated from project.yml via XcodeGen.

Includes CI build matrix (macOS 14/15 × Debug/Release), issue templates,
backlog, and API/backend handoff docs.
