- 新增 $white 语义变量 + --tk-font-display Token
- 44 处 #fff → $white，2 处 background: #fff → $card
- 14 处 border-radius 硬编码统一为 $r-xs/$r-lg/$r
- 3 处 TSX inline 颜色提取为 SCSS 类（exchange/orders/action-inbox）
- ErrorBoundary 重构：6 个 inline style → SCSS 类 + Design Token
- 2 处离调色板颜色修正（#0284C7→$tx2, #94A3B8→$tx3）
- 2 处静默 catch 块添加状态清理（article/health）
- 趋势页补 Loading/EmptyState；咨询页 GuestGuard 统一
- 4 处 #FFFFFF → $white（mixins/index/exchange/variables）
