+## Design Techniques
+
+- Extensive use of circles (ellipse) as image placeholders and decorative elements, embodying the "circle" theme
+- Multi-layer dark gray cards stacked to create dark mode hierarchy and depth
+- Neon lime as the only bright color, used for CTA buttons, decorative dots, and dividers, creating strong contrast
+- Left vertical decorative bars + numbering system, adding structural sense to the layout
+- roundRect rounded buttons with neon lime fill, highlighting calls to action
+
+## Reference Script
+
+Full build script available in `build.sh`.
+**Recommended slides to read for understanding core design techniques**:

+  No need to read all — skim 2-3 representative slides.
