+# S15-blueprint-grid — Engineering Blueprint Grid
+
+## Style Overview
+
+Deep blue background with white grid lines and gold markers creates a precise engineering drafting aesthetic.
+
+- **Scene**: Technical planning, engineering blueprints, system architecture
+- **Mood**: Precise, professional, engineering-oriented
+- **Color Tone**: Deep blue + white grid + gold accents
+
+## Color Palette
+
+| Name         | Hex    | Usage                        |
+| ------------ | ------ | ---------------------------- |
+| Deep Blue    | 1B3A5C | Background                   |
+| Bright Blue  | 4A90D9 | Highlight color, titles      |
+| White        | FFFFFF | Grid lines, body text        |
+| Gold Warning | E8C547 | Warning markers, CTA buttons |
+
+## Design Techniques
+
+- Use rect to draw evenly spaced horizontal/vertical grid lines (opacity 0.25), simulating blueprint graph paper
+- Use ellipse as positioning marker points, suggesting key nodes in a coordinate system
+- All shapes use low transparency overlay to maintain blueprint hierarchy
+- Typography uses monospace or bold sans-serif fonts to reinforce engineering drafting aesthetic
+
+## Reference Script
+
+Full build script available in `build.sh`.
+**Recommended slides to read for understanding core design techniques**:
+
+- **Slide 1 (hero)** — Grid line drawing method and layout spacing
+- **Slide 3 (pillars)** — Multi-column layout + grid-aligned typesetting technique
+  No need to read all — skim 2-3 representative slides.
