-## Design Context
-
-### Users
-
-Developers and power users who manage multiple AI accounts (Google Gemini, Claude) through a desktop Electron app. They use IDEs like Cursor, OpenCode, and Windsurf. They need to monitor token usage across accounts in real-time to avoid quota exhaustion.

-### Brand Personality
-
-- **Professional**: Clean, precise, no clutter
-- **Technical**: Data-dense but readable, developer-friendly
-- **Efficient**: Information at a glance, minimal clicks
-- 3 words: "precise", "technical", "focused"
-
-### Aesthetic Direction
-
-- Dark mode primary (this is a developer tool used for long sessions)
-- Deep navy/slate backgrounds, not pure black
-- Sharp accent colors for data visualization (subtle blues, teals, amber for warnings)
-- High information density without visual noise
-- Monospace for numbers/data, clean sans-serif for UI chrome
-- No gradients on text, no glassmorphism, no rounded-everything

-### Design Principles
-
-1. Data first — charts and numbers are the heroes
-2. Every pixel earns its place — no decorative elements
-3. Density over whitespace — developers want to see everything
-4. Motion only for state changes — no gratuitous animations
-5. Consistent with shadcn/ui + Tailwind system already in place
