 ## 2025-12-31 - [Asset Optimization]
 **Learning:** This repository consists entirely of static assets with no build system. Performance gains come exclusively from optimizing these assets (e.g., lossless PNG compression) rather than code changes.
 **Action:** Use tools like `optipng` to reduce file sizes without quality loss. Handle filenames with spaces carefully in shell commands.

+## 2025-01-25 - [Asset Optimization Wins]
+**Learning:** Found significant reductions in 'older' assets (e.g., Cave Girl Torso reduced by ~78KB/28%), confirming the README's note about older textures being less refined.
+**Action:** Prioritize optimization of assets in older series/folders as they likely yield better compression ratios.
