+
+### Session 5 - 2026-08-20 (Afternoon)
+**Status:** ✅ Prestige System Added
+
+#### What was done:
+- Created complete prestige/reset system with Stellar Essence currency
+- Formula: floor(sqrt(totalStardust / 1,000,000)) essence per prestige
+- Each essence provides +10% production bonus (stacks multiplicatively)
+- Added 6 prestige upgrades: Cosmic Fingers, Stellar Touch, Essence Amplifier, Quantum Garden, Accelerated Growth, Temporal Manipulation
+- Created PrestigeUI module for rendering and managing prestige tab
+- Added prestige particle effects (cosmic explosion on reset)
+- Added prestige sound effect (ethereal whoosh via Web Audio API)
+- Integrated prestige multiplier into click power, production, building costs, and offline progress
+- Added prestige button to footer with glow animation when eligible
+- Updated game state to persist prestige data across resets
+
+#### Files modified/created:
+- `js/prestige.js` - New file with Prestige system (essence calculation, upgrades, multipliers)
+- `js/prestigeUI.js` - New file with PrestigeUI module (tab rendering, event handling)
+- `js/game.js` - Added prestige fields to state, integrated multipliers into calculations
+- `js/particles.js` - Added createPrestigeEffect() method
+- `js/audio.js` - Added playPrestige() sound effect
+- `css/game.css` - Added prestige button styles, tab styles, upgrade card styles
+- `index.html` - Added prestige tab and script tags
+- `dev-journal.md` - Updated with session log
+
+#### Next goals:
+- Achievement expansion (prestige-related achievements)
+- Mobile touch optimizations
+- Consider adding more visual polish to the click button
