 # Design System Overview
 
+> [!info] Current version: **Amaneh v2.7.0** (commit 56fc84e, 2026-05-29)
+> Major full-app redesign. Key changes: warm-earth palette (Saffron / Pistachio / Persian Blue / Honey / Pomegranate), three-font stack (Source Serif 4 italic / IBM Plex Sans / IBM Plex Mono), SealMark SVG logo (saffron octagon + serif italic wordmark), CSS custom properties (`--amn-*`) in `global.css`, settings-drawer preset picker simplified to single Amaneh entry.
+
 The frontend design system is built on **Material-UI v7** with project-specific tokens, an LTR + RTL-aware emotion cache, and a user-controllable settings drawer (mode, layout, color preset, font, direction).
