+# S23-isometric-clean — Isometric Clean Tech
+
+## Style Overview
+
+Light blue-gray background using diamond and rectangle combinations to create isometric/3D block visuals, conveying a clean and modern technological feel.
+
+- **Scene**: Tech products, SaaS platforms, data display
+- **Mood**: Clean, modern, technological
+- **Color Tone**: Light blue-gray base + blue accent + light gray layers
+
+## Color Palette
+
+| Name            | Hex    | Usage                                          |
+| --------------- | ------ | ---------------------------------------------- |
+| Light Blue-Gray | F0F4F8 | Background base color                          |
+| Blue            | 4A90D9 | Primary accent color, isometric block top face |
+| Light Gray      | E8ECF1 | Block side face, auxiliary color block         |
+
+## Design Techniques
+
+- Diamond shapes simulate isometric perspective block top faces, rectangles serve as side faces, combined to create 3D block effects
+- Blocks arranged in grid pattern, forming isometric spatial sense
+- Restrained color scheme (only blue-gray), maintaining clean and uncluttered appearance
+- Typography uses modern sans-serif fonts like Inter Bold
+
+## Reference Script
+
+Complete build script is in `build.sh`.
+**Recommended slides to read for understanding core design techniques**:
+
+- **Slide 1 (hero)** — How to construct isometric blocks using diamond + rectangle combinations
+- **Slide 3 (pillars)** — Grid layout with multiple block arrangements
+  No need to read all — skim 2-3 representative slides.
