 ✔ Works across Go, PHP, JavaScript, Rust, and Python.
 ✔ Future-proof for centuries (supports up to the year 2320+).
 
+
+✅ Uses 12-digit milliseconds (future-proof for ~31,000 years).
+✅ Uses a 2-digit random number (00-99) to avoid collisions.
+✅ Ensures fixed 8-character Base-62 output.
+✅ Time-ordered for better database indexing.
+✅ Efficient and compact in multiple languages.
+
+This should be rock-solid for high-performance, compact, and unique IDs 🚀.
