-# Mono Design System - Qt Implementation Guide
-
-**Version:** 1.0
-**Based on:** [decode-ui Design System](C:\Users\Administrator\decode-ui\.agents\skills\design-system\SKILL.md)
-**Theme Library:** dark.qss, light.qss, style.qss
-**Last Updated:** April 2026
-
----
-
-## Brand & Mission
-
-**Visual Style:** Minimal, clean, high-contrast, playful, matrix-inspired with hacker-chic aesthetic
-
-**Design Philosophy:**
-- **Keyboard-first:** All interactive elements are fully navigationable via keyboard
-- **Accessibility:** WCAG 2.2 AA compliant - color contrast, focus states, motion preferences
-- **Semantic:** Use class attributes to convey component intent, not layout
-- **Density:** Compact spacing (4–48px scale) for data-dense interfaces
-- **Typography:** Space Mono for UI, JetBrains Mono for code/data
