Summary

Prepare 26.11.4 with an updated toolchain, simpler desktop integration, and more consistent single-column pages.

Toolchain / CI   Flutter 3.50, Dart 3.14, dependency updates, Pigeon generation
Desktop          Upstream window/tray APIs; Linux system title bar and Skia
Setup / Connect  Responsive setup; one stable session card with placeholders
Shared UI        Reduced motion, concise labels, aligned sections and spacing
Documentation    System requirements and refreshed localized showcase references

Remove the connection-explanation section while retaining connection plans, runtime identity, traffic, routing, and health information. Keep existing fonts and single-column layouts.

Evidence

• Before: Connection and session details occupied separate sections with state-dependent layout; setup and shared pages had uneven spacing and repeated guidance.
  After: Setup redistributes content responsively; one session section preserves disconnected placeholders and truncates long node names. Shared sections and setting rows align their content consistently.
• flutter analyze --no-pub: passed.
• flutter test --no-pub --reporter expanded: 2305 passed, 5 skipped.
• Build-script unit tests: 35 passed, 1 skipped.
• Production-entry debug builds succeeded for macOS, iOS Simulator, and Android.
• Reviewed native mock captures across macOS, iPhone, iPad, and Android phone/tablet/Desktop in English, Chinese, and Russian. These captures do not exercise a real VPN connection.

Merge Danger

Door: Two-way. No database migration or rewriting of saved configurations or caches.

Blast Radius: Cross-platform. Toolchain/dependency updates and desktop window, tray, and rendering behavior. Linux uses Skia to avoid blank content on Mesa SVGA3D; Windows/Linux GPU behavior was not validated on this host.
