feat: prioritize lazy options loading and live overview wiring

- queue OPS-001 Caddy route for vd1.uncloud.vpn
- lazy-load options expirations/chains per expiry
- wire overview to live quote data and persisted portfolio config
- extend browser test to verify live quote metadata

+## Fast Follow-up Backlog
+
+### DATA-002A: Lazy Options Loading [P0, S] **[depends: DATA-002]**
+**As a** trader, **I want** the options page to render immediately **so that** it feels responsive and usable.
+
+**Acceptance Criteria:**
+- Initial page load fetches only expirations plus one default expiry chain
+- Changing expiry fetches that expiry on demand
+- Browser test verifies `/options` becomes visible quickly
+- No visible 500/runtime error during page load
+
+**Dependencies:** DATA-002
+
+### DATA-001A: Live Overview Price Wiring [P0, S] **[depends: DATA-001, PORT-001]**
+**As a** portfolio manager, **I want** the overview cards to use live quote data **so that** the displayed spot/LTV values are trustworthy.
+
+**Acceptance Criteria:**
+- Overview page uses live quote from service instead of hardcoded `215.0`
+- Display source and last updated timestamp
+- Margin call / LTV calculations use configured portfolio values
+- Browser test verifies overview renders with live data metadata
+
+**Dependencies:** DATA-001, PORT-001
+
+### OPS-001: Caddy Route for Production Dashboard [P1, S] **[depends: deploy-stable]**
+**As a** VPN user, **I want** to reach the deployed dashboard at `vd1.uncloud.vpn` **so that** I can access it without SSH port forwarding.
+
+**Acceptance Criteria:**
+- Caddy route proxies `vd1.uncloud.vpn` to local deployment container
+- Route works over the VPN only
+- Health check succeeds through Caddy
+- Deployment docs include the route and where it lives
+
+**Dependencies:** stable deployed app on VPS
+
 ## Implementation Priority Queue
 
-1. **DATA-001** - Unblock all other features
+1. **DATA-002A** - Fix options UX/performance regression
-2. **PORT-001** - Enable user-specific calculations
+2. **DATA-001A** - Remove misleading mock overview price
-3. **DATA-002** - Core options data
+3. **OPS-001** - Add Caddy route once app behavior is stable
 4. **DATA-003** - Risk metrics
 5. **PORT-002** - Risk management safety
 6. **EXEC-001** - Core user workflow
