AI Mascot IP Display (浠宝/福宝) — Session Summary

Goal

Complete and verify the mascot IP形象 system (浠宝/福宝) across all touchpoints: database, backend API, login/registration, profile settings, AI chat display, and floating avatar

✅ Investigated all mascot-related files and verified completion state
✅ Fixed hardcoded typing indicator in chat.vue (🤖 → {{ mascotIcon || '🤖' }})
✅ Added dynamic CSS class mascot-{code} to chat nav bar
✅ Added mascot-specific nav gradient: .mascot-xibao (warm orange), .mascot-fubao (golden)
✅ Added mascot-specific avatar styling (gradient + colored border)
✅ Added welcome icon float animation with per-mascot delays
✅ Added mascot selection to user-edit.vue (registration flow):
- Mascot card UI (浠宝/福宝 with gradient icons)
- selectMascot(code) method
- form.mascot field in data
- mascot passed in all API calls (saveUserInfo, directRegister, updateUserInfo)
- mascot saved to uni.getStorageSync('userInfo') on navigation
- Card styles with active state and gradient backgrounds
✅ Verified other mascot components:
- MascotEnum.java ✅ (XIBAO/FUBAO with code, gender, persona)
- User.java:95 ✅ (private String mascot; field)
- AIChatController.java ✅ (injects mascot_name/mascot_gender/mascot_persona into Dify)
- UserMascotController.java ✅ (POST set/get)
- profile.vue ✅ (mascot-selector with cards)
- AIFloatingAvatar.vue ✅ (reads from storage)
- chat.vue ✅ (reads from userInfo onLoad, mascot-specific styling)

🔄 Verify all diagnostics clean
🔄 (Optional) Test full mascot flow: login → user-edit mascot selection → profile → AI chat

Added mascot selection to user-edit.vue during registration (not login.vue), since WeChat login is one-tap
Used gradient/card UI matching profile.vue style for consistency
Saved mascot to userInfo storage in navigateToHome() to ensure chat.vue reads it immediately

Pre-existing LSP warnings (unused e variables, string concatenation) — NOT introduced by edits
小程序 limits: no optional chaining, no CSS Grid — all CSS uses flexbox
chat.vue has 4 pre-existing var declarations — kept as-is for legacy compatibility
