+- 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? [NEEDS CLARIFICATION: Should page remain active or show "Event Completed" message]
+- 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

 ## Notes
 
-**Clarifications Needed:**
-1. Post-countdown behavior: What should display when countdown reaches zero?
-2. Post-event behavior: Should page remain active or show completion message after Oct 31 2025?
+**Edge Case Resolutions:**
+1. Post-countdown behavior: Display "🎃 EVENT STARTING NOW! 🎃" message when countdown reaches zero
+2. Post-event behavior: Display "👻 EVENT COMPLETED - Thanks for joining! 👻" message after Oct 31 2025 21:00 GMT+8
+3. JavaScript disabled: All static content remains accessible with fallback message "Enable JavaScript for live countdown"
+4. Very small screens (< 320px): Use ultra-minimal ASCII art (simplified version) prioritizing readability
 
 **Design Philosophy:**
 - Extreme minimalism inspired by Homebrew package manager aesthetic
