merge atio features into unified main branch

Merge atio's UI improvements (sidebar layout, chat fixes, checkout
simplification, z-index fixes) into cfaun's module system (links,
tasks, expenses).

Conflicts resolved keeping cfaun's versions for:
- Home.vue (multi-action FAB with quick actions)
- di-container.ts, useModularNavigation.ts (module registry)
- nostr-feed/index.ts (disabled, replaced by links)
- package.json/lock (cfaun's dependency tree)

Branding files kept as cfaun's — per-target branding should come
from build-time config, not branches.

Removed: target-ui.md (atio reference doc, no longer needed)

Next: refactor app.config.ts to read enabled modules from VITE_*
env vars so per-target config lives in the deploy flake.

+### **BaseService Pattern**
+
+All services MUST extend `BaseService` (`src/core/base/BaseService.ts`) for standardized initialization and dependency management:
+
+**Service Implementation Pattern:**
+
+```typescript
+import { BaseService } from '@/core/base/BaseService'
+
+export class MyService extends BaseService {
+  // 1. REQUIRED: Declare metadata with dependencies
+  protected readonly metadata = {
+    name: 'MyService',
+    version: '1.0.0',
+    dependencies: ['AuthService', 'RelayHub', 'VisibilityService']
+  }
+
+  // 2. REQUIRED: Implement onInitialize
+  protected async onInitialize(): Promise<void> {
+    // Dependencies are auto-injected based on metadata.dependencies
+    // Available: this.authService, this.relayHub, this.visibilityService, etc.
+
+    // Register with VisibilityService if using WebSockets
+    if (this.visibilityService) {
+      this.visibilityService.registerService(
+        this.metadata.name,
+        this.onResume.bind(this),
+        this.onPause.bind(this)
+      )
+    }
+
+    // Your initialization logic
+    await this.setupConnections()
+  }
+
+  // 3. Implement visibility handlers for WebSocket services
+  private async onResume(): Promise<void> {
+    // Reconnect and restore state when app becomes visible
+  }
+
+  private async onPause(): Promise<void> {
+    // Pause operations when app loses visibility
+  }
+
+  // 4. Optional: Cleanup logic
+  protected async onDispose(): Promise<void> {
+    // Cleanup connections, subscriptions, etc.
+  }
+}
+```
+
+**BaseService Features:**
+- **Automatic dependency injection** based on `metadata.dependencies`
+- **Retry logic** with configurable retries and delays
+- **Reactive state** via `isInitialized`, `isInitializing`, `initError`
+- **Event emission** for service lifecycle events
+- **Error handling** with consistent logging
+- **Debug helpers** for development
+
+**Service Initialization:**
+```typescript
+// In module's index.ts
+const myService = new MyService()
+container.provide(SERVICE_TOKENS.MY_SERVICE, myService)
+
+// Initialize with options
+await myService.initialize({
+  waitForDependencies: true,  // Wait for dependencies before initializing
+  maxRetries: 3,              // Retry on failure
+  retryDelay: 1000           // Delay between retries (ms)
+})
+```
+
+**Available Dependencies:**
+When you list these in `metadata.dependencies`, they'll be auto-injected:
+- `'RelayHub'` → `this.relayHub`
+- `'AuthService'` → `this.authService`
+- `'VisibilityService'` → `this.visibilityService`
+- `'StorageService'` → `this.storageService`
+- `'ToastService'` → `this.toastService`
+- `'LnbitsAPI'` → `this.lnbitsAPI`

-**Reference**: [Vue.js Forms Documentation](https://vuejs.org/guide/essentials/forms.html)
+### **CSS and Styling Guidelines**
 
-**❌ NEVER do this:**
+**CRITICAL: Always use semantic, theme-aware CSS classes**
-```vue
-<!-- Wrong: Manual form handling without vee-validate -->
-<form @submit.prevent="handleSubmit">
 
-<!-- Wrong: Direct v-model bypasses form validation -->
+- ✅ **Use semantic classes** that automatically adapt to light/dark themes
-<Input v-model="myValue" />
+- ❌ **Never use hard-coded colors** like `bg-white`, `text-gray-500`, `border-blue-500`
 
-<!-- Wrong: Manual validation instead of using meta.valid -->
+**Preferred Semantic Classes:**
-<Button :disabled="!name || !email">Submit</Button>
+```css
+/* Background Colors */
+bg-background      /* Instead of bg-white */
+bg-card           /* Instead of bg-gray-50 */

+text-muted-foreground/70     /* For transparency */
 ```
 
-**✅ ALWAYS do this:**
+**Why Semantic Classes:**
-```vue
+- Ensures components work in both light and dark themes
-<!-- Correct: Uses form.handleSubmit for proper form handling -->
+- Maintains consistency with Shadcn/ui component library
-<form @submit="onSubmit">
+- Easier to maintain and update theme colors globally
-  
+- Better accessibility
-<!-- Correct: Uses FormField with componentField binding -->
-<FormField v-slot="{ componentField }" name="fieldName">
-  <FormControl>
-    <Input v-bind="componentField" />
-  </FormControl>
-</FormField>
-

-### **Android 14/15 Camera Workarounds**
-
-**Non-Standard MIME Type Workaround:**
-```html
-<!-- Add non-standard MIME type to force camera access -->
-<input type="file" accept="image/*,android/allowCamera" capture="environment" />
-```
-
-**Plain File Input Fallback:**
-```html
-<!-- Fallback: Plain file input shows both camera and gallery options -->
-<input type="file" accept="image/*" />
-```
-
-### **Industry-Standard Patterns**
-
-**1. Page Visibility API (Primary Solution):**
-```javascript
-// Modern browsers: Use Page Visibility API instead of beforeunload
-document.addEventListener('visibilitychange', function() {
-  if (document.visibilityState === 'visible') {
-    // Resume critical operations, restore connections
-    resumeOperations()
-  } else {
-    // Save state, pause operations for battery conservation
-    saveStateAndPause()
-  }
-})
-```
-
-**2. Conditional BeforeUnload Protection:**
-```javascript
-// Only add beforeunload listeners when user has unsaved changes
-const addFormProtection = (hasUnsavedChanges) => {
-  if (hasUnsavedChanges) {
-    window.addEventListener('beforeunload', preventUnload)
-  } else {
-    window.removeEventListener('beforeunload', preventUnload)
-  }
-}
-```
-
-**3. Session Recovery Pattern:**
-```javascript
-// Save form state on visibility change
-document.addEventListener('visibilitychange', () => {
-  if (document.visibilityState === 'hidden') {
-    localStorage.setItem('formDraft', JSON.stringify(formData))
-  }
-})
-
-// Restore on page load
-window.addEventListener('load', () => {
-  const draft = localStorage.getItem('formDraft')
-  if (draft) restoreFormData(JSON.parse(draft))
-})
-```
-
-### **Testing & Debugging**
-
-**Reproduction Steps:**
-1. Open form with file upload on mobile device
-2. Select camera input during image upload operations
-3. Turn screen off/on during upload process
-4. Switch between apps during file selection
-5. Low memory conditions during camera usage
-
-**Success Indicators:**
-- User sees confirmation dialog instead of losing form data
-- Console warnings show visibility change detection working
-- Form state preservation during app switching
-- Camera input properly separates from gallery input
-
-**Debug Console Messages:**
-```javascript
-// Look for these defensive programming console messages
-console.warn('Form submission blocked during file upload')
-console.warn('Visibility change detected while form is open')
-```
-

+# Link Aggregator Implementation Plan
+
+## Overview
+
+Transform the nostr-feed module into a Reddit-style link aggregator with support for:
+- **Link posts** - External URLs with Open Graph previews
+- **Media posts** - Images/videos with inline display
+- **Self posts** - Text/markdown content
+
+## NIP Compliance
+
+| NIP | Purpose | Usage |
+|-----|---------|-------|
+| NIP-72 | Moderated Communities | Community definitions (kind 34550), approvals (kind 4550) |
+| NIP-22 | Comments | Community posts (kind 1111) with scoped threading |
+| NIP-92 | Media Attachments | `imeta` tags for media metadata |
+| NIP-94 | File Metadata | Reference for media fields |
+| NIP-25 | Reactions | Upvote (`+`) / Downvote (`-`) |
+| NIP-10 | Reply Threading | Fallback for kind 1 compatibility |
+
+## Event Structure
+
+### Submission (kind 1111)
+
+```jsonc
+{
+  "kind": 1111,
+  "content": "<self-post body or link description>",
+  "tags": [
+    // Community scope (NIP-72 + NIP-22)
+    ["A", "34550:<community-pubkey>:<community-d>", "<relay>"],
+    ["a", "34550:<community-pubkey>:<community-d>", "<relay>"],
+    ["K", "34550"],
+    ["k", "34550"],
+    ["P", "<community-pubkey>"],
+    ["p", "<community-pubkey>"],
+
+    // Submission metadata
+    ["title", "<post title>"],
+    ["post-type", "link|media|self"],
+
+    // Link post fields
+    ["r", "<url>"],
+    ["preview-title", "<og:title>"],
+    ["preview-description", "<og:description>"],
+    ["preview-image", "<og:image>"],
+    ["preview-site-name", "<og:site_name>"],
+
+    // Media post fields (NIP-92)
+    ["imeta", "url <url>", "m <mime>", "dim <WxH>", "blurhash <hash>", "alt <desc>"],
+
+    // Common
+    ["t", "<hashtag>"],
+    ["nsfw", "true|false"]
+  ]
+}
+```
+
+### Comment on Submission (kind 1111)
+
+```jsonc
+{
+  "kind": 1111,
+  "content": "<comment text>",
+  "tags": [
+    // Root scope (the community)
+    ["A", "34550:<community-pubkey>:<community-d>", "<relay>"],
+    ["K", "34550"],
+    ["P", "<community-pubkey>"],
+
+    // Parent (the submission or parent comment)
+    ["e", "<parent-event-id>", "<relay>", "<parent-pubkey>"],
+    ["k", "1111"],
+    ["p", "<parent-pubkey>"]
+  ]
+}
+```
+
+## Implementation Phases
+
+### Phase 1: Core Data Model
+- [x] Create feature branch
+- [x] Document plan
+- [x] Create `types/submission.ts` - Type definitions
+- [x] Create `SubmissionService.ts` - Submission CRUD
+- [x] Create `LinkPreviewService.ts` - OG tag fetching
+- [x] Extend `FeedService.ts` - Handle kind 1111
+
+### Phase 2: Post Creation
+- [x] Create `SubmitComposer.vue` - Multi-type composer
+- [x] Add link preview on URL paste
+- [x] Add NSFW toggle
+- [x] Add route `/submit` for composer
+- [ ] Integrate with pictrs for media upload (Future)
+
+### Phase 3: Feed Display
+- [x] Create `SubmissionRow.vue` - Link aggregator row (Reddit/Lemmy style)
+- [x] Create `VoteControls.vue` - Up/down voting
+- [x] Create `SortTabs.vue` - Sort tabs (hot, new, top, controversial)
+- [x] Create `SubmissionList.vue` - Main feed container
+- [x] Create `SubmissionThumbnail.vue` - Thumbnail display
+- [x] Add feed sorting (hot, new, top, controversial)
+- [x] Add score calculation
+- [x] Create `LinkAggregatorTest.vue` - Test page with mock data & live mode
+
+### Phase 4: Detail View
+- [x] Create `SubmissionDetail.vue` - Full post view with content display
+- [x] Create `SubmissionComment.vue` - Recursive threaded comments
+- [x] Create `SubmissionDetailPage.vue` - Route page wrapper
+- [x] Add route `/submission/:id` for detail view
+- [x] Add comment sorting (best, new, old, controversial)
+- [x] Integrate comment submission via SubmissionService.createComment()
+
+### Phase 5: Communities (Future)
+- [ ] Create `CommunityService.ts`
+- [ ] Create community browser
+- [ ] Add moderation queue
+
+## Ranking Algorithms
+
+### Hot Rank (Lemmy-style)
+```typescript
+function hotRank(score: number, createdAt: Date): number {
+  const order = Math.log10(Math.max(Math.abs(score), 1))
+  const sign = score > 0 ? 1 : score < 0 ? -1 : 0
+  const seconds = (createdAt.getTime() - EPOCH.getTime()) / 1000
+  return sign * order + seconds / 45000
+}
+```
+
+### Controversy Rank
+```typescript
+function controversyRank(upvotes: number, downvotes: number): number {
+  const total = upvotes + downvotes
+  if (total === 0) return 0
+  const magnitude = Math.pow(total, 0.8)
+  const balance = total > 0 ? Math.min(upvotes, downvotes) / Math.max(upvotes, downvotes) : 0
+  return magnitude * balance
+}
+```

+
+## Migration Strategy
+
+1. **Backwards compatible** - Continue supporting kind 1 notes
+2. **Gradual adoption** - Add kind 1111 alongside existing
+3. **Feature flag** - Toggle between classic feed and link aggregator view
