chore: bump version to 0.3.1

- Add multi-stage Dockerfile (Flutter build → nginx:alpine)
- Add nginx.conf with SPA routing, gzip, and caching
- Add Gitea workflow for release-triggered builds
- Document release procedure in AGENTS.md

Deploys to port 8092, auto-updates via Watchtower.

     * Tag after updating `pubspec.yaml` version and CHANGELOG
     * Push tags with `git push --tags`
 
+### 🚀 Release Procedure
+
+This project uses version-tag-based CI/CD. Releases trigger automated Docker builds and deployments.
+
+**Release Steps:**
+
+1. Update version in `pubspec.yaml` (bump major.minor.patch, not build number)
+2. Update `CHANGELOG.md` with changes under `## [x.x.x] - YYYY-MM-DD`
+3. Commit changes: `git commit -m "chore: release vX.X.X"`
+4. Create git tag: `git tag vX.X.X`
+5. Push with tags: `git push origin master --tags`
+6. Create release in Gitea UI (git.schweitz.net → Releases → New Release)
+   * Select the tag
+   * Add release notes (can copy from CHANGELOG)
+   * **Publish** the release (this triggers CI/CD)
+
+**What happens on release:**
+
+* Gitea CI builds Flutter web app in Docker
+* Image pushed to `git.schweitz.internal/jpmschweitzer/tatlock-ui:latest` and `:vX.X.X`
+* Watchtower detects new image and auto-updates running container
+* App available at `http://tower:8092` (and eventually `home.schweitz.net`)
+
+**Rollback:**
+
+* In Portainer, update image tag to previous version (e.g., `:v0.2.0`)
+* Or: `docker pull git.schweitz.internal/jpmschweitzer/tatlock-ui:v0.2.0`
+
 ### 🧪 Testing Requirements
+
 * **Always add tests for new code before committing.** No exceptions.
 * Tests should cover the happy path and key edge cases.
 * Run `flutter test` before committing to ensure all tests pass.

 ### 📝 Changelog Maintenance

 * **Update `CHANGELOG.md`** with every user-facing change.

+* Format: `## [Unreleased] - YYYY-MM-DD` followed by `### Added`, `### Changed`, or `### Fixed`.
+
+### 🎨 UI Patterns (MUST READ BEFORE CHANGES)
+
+* **Before modifying the widget tree**, read `docs/UI_LAYOUT.md` to understand established patterns.
+* Investigate existing implementations in the codebase before creating new components.
+* **DO NOT** reinvent wheels - check if shared components already exist in `lib/shared/components/`.
+* Look at similar features for reference patterns (e.g., how other list views, forms, or CRUD screens are built).
+* Deviating from established patterns creates inconsistency and technical debt.

+}

+// Section headers auto-generate from unique section values
+// Visibility: items.map((i) => i.section).toSet().length > 1

+
+#### Route Configuration Driven
+
+Sections are defined in the feature's route configuration, not the widget:
+
+```dart
+/// In lib/features/control_room/router.dart
+
+enum ControlRoomNav {
+  // Portainer section
+  containers('containers', 'Containers', Icons.dns, 'Portainer'),
+  networks('networks', 'Networks', Icons.hub, 'Portainer'),
+  volumes('volumes', 'Volumes', Icons.storage, 'Portainer'),
+  images('images', 'Images', Icons.photo_library, 'Portainer'),
+  // NPM section (future)
+  proxyHosts('proxy-hosts', 'Proxy Hosts', Icons.public, 'NPM'),
+  redirections('redirections', 'Redirections', Icons.alt_route, 'NPM'),
+  // Authentik section (future)
+  users('users', 'Users', Icons.people, 'Authentik'),
+  groups('groups', 'Groups', Icons.group_work, 'Authentik');
+
+  const ControlRoomNav(this.id, this.label, this.icon, this.section);
+
+  final String id;
+  final String label;
+  final IconData icon;
+  final String section;
+
+  NavItem toNavItem() => NavItem(
+        id: id,
+        label: label,
+        icon: icon,
+        section: section,
+      );
+}
+```
+
+The NavPanel widget receives items and auto-generates section headers based on unique section values in the list. No section logic lives in the widget - it just renders what the route config provides.
