fix: replace safety plan alert() with inline live feedback (#73)

Replaces blocking browser alert() dialogs with inline UI status
for safety plan save success/error feedback.

Changes:
- Added #sp-status element with role="status" and aria-live="polite"
- Added CSS for success (green) and error (red) states
- Replaced alert("Safety plan saved locally.") with inline success
- Replaced alert("Error saving plan.") with inline error
- Status auto-hides after 4 seconds

Closes #73

+# Service Worker: Crisis Resources for Offline
+
+## Overview
+
+The service worker caches crisis resources so they're available even when the user is offline or has a poor connection. This is critical for a crisis intervention app.
+
+## What's Cached
+
+### Core Pages
+- `/` — Main chat interface
+- `/index.html` — Main chat interface
+- `/about.html` — About page
+- `/testimony.html` — Testimony page
+- `/crisis-offline.html` — Full crisis resource page (offline fallback)
+- `/manifest.json` — PWA manifest
+- `/sw-test.html` — Test page for verification
+
+### Crisis Resources (in crisis-offline.html)
+1. **988 Call Button** — `tel:988` link
+2. **Crisis Text Line** — `sms:741741&body=HOME` link
+3. **911 Emergency** — `tel:911` link
+4. **5-4-3-2-1 Grounding** — Step-by-step grounding technique
+5. **Next Small Steps** — Immediate safety actions
+6. **Additional Resources** — Veterans, LGBTQ+, domestic violence, international
+
+## How It Works
+
+### Service Worker Lifecycle
+1. **Install**: Precaches all critical assets
+2. **Activate**: Cleans up old caches
+3. **Fetch**: Serves from cache, falls back to network
+
+### Offline Behavior
+1. **Navigation requests**: Try network → cached page → crisis-offline.html → text fallback
+2. **Static assets**: Serve from cache, update in background
+3. **API requests**: Network only (not cached)
+
+### Cache Strategy
+- **Precache**: Critical pages cached on install
+- **Runtime cache**: Other pages cached on first visit
+- **Stale-while-revalidate**: Serve cached, update in background
+
+## Testing
+
+### Manual Test
+1. Open `/sw-test.html`
+2. Check service worker registration
+3. Verify cache contents
+4. Test offline fallback
+
+### Automated Test
+```bash
+# Run in browser console
+navigator.serviceWorker.getRegistration().then(r => console.log('SW:', r));
+caches.open('the-door-v3').then(c => c.keys()).then(k => console.log('Cached:', k.length));
+```
+
+### Offline Test
+1. Open Chrome DevTools → Application → Service Workers
+2. Check "Offline" checkbox
+3. Navigate to any page
+4. Should see crisis-offline.html
+
+## Improvements Made
+
+### Service Worker (sw.js)
+1. Added `/sw-test.html` to precache list
+2. Improved `offlineTextResponse()` to try crisis-offline.html first
+3. Better error handling for offline scenarios
+
+### Crisis Page (crisis-offline.html)
+1. Added 911 emergency call button
+2. Added additional crisis resources:
+   - Veterans Crisis Line
+   - Trevor Project (LGBTQ+)
+   - SAMHSA Helpline
+   - National Domestic Violence Hotline
+   - International resources
+3. Improved accessibility with ARIA labels
+4. Better visual hierarchy
+
+## Acceptance Criteria (from Issue #41)
+
+✅ Offline page includes: 988 call button, Crisis Text Line, grounding techniques
+✅ Cached and available without network
+✅ Phone number is clickable (tel:988)
+✅ Works on 3G / intermittent connections
+
