What it may solve
A DeepSeek Harness plugin (dual-face host + browser) for watching your DeepSeek account **balance** and estimating **token-based costs**, with prices configured per **model × peak/off-peak period** online. Everything lives in a unified modal (opened from the sidebar-footer **Balance** button); a **session-header** button shows a live "Session ≈xx CNY". UI copy is bilingual (Chinese / English, following the host UI language).
