## ⚡ Quick Guidelines
- ✅ Focus on WHAT users need and WHY
- ❌ Avoid HOW to implement (no tech stack, APIs, code structure)
- 👥 Written for business stakeholders, not developers

## User Scenarios & Testing *(mandatory)*

### Primary User Story
As a McDonald's China IT team member, I want to view the Halloween 2025 event announcement page so that I can learn about the event details, activities, and know when it starts through a countdown timer.

### Acceptance Scenarios
1. **Given** a team member visits the event page on desktop, **When** they load the page, **Then** they see ASCII art logo, event details in bilingual format, and a live countdown timer
2. **Given** a team member visits the event page on mobile, **When** they load the page, **Then** all content remains legible including ASCII art and the page is fully responsive
3. **Given** the event date/time approaches, **When** a team member views the countdown, **Then** it accurately reflects time remaining in GMT+8 timezone
4. **Given** a team member reads event information, **When** they scroll through the page, **Then** they can find event date (Oct 31 2025), time (18:00-21:00), location (MITA Building 2F Pantry), activities (cosplay, debugging games, lucky draw), and organizer contact (jessi.pan@cn.mcd.com)

### Edge Cases
- What happens when the countdown reaches zero? Display "🎃 EVENT STARTING NOW! 🎃" message
- How does ASCII art render on very small screens (< 320px)? System must provide mobile-optimized version
- What happens if user visits after event date? Display "👻 EVENT COMPLETED - Thanks for joining! 👻" message after Oct 31 2025 21:00 GMT+8
- What if JavaScript is disabled? Countdown won't work but all static content must remain accessible
