+# BUILD_PR — Index Full Height + SEO Content
+
+## Purpose
+Ensure /index.html fills full viewport height and add light SEO/engaging content.
+
+## Scope
+- /index.html only
+- No changes to other pages
+- No layout restructuring beyond height fill
+
+## Changes
+1. Ensure page fills viewport height (min-height: 100vh applied at shell level excluding page-shell rule constraints)
+2. Add short engaging intro content:
+   - lightweight description of platform
+   - keywords for SEO
+   - readable, non-intrusive
+
+## Content Addition (example)
+"Build, play, and explore classic-style games and modern tools in one place. 
+This platform showcases interactive samples, arcade-inspired games, and developer tools designed for learning, experimentation, and performance testing."
+
+## Rules
+- No inline styles
+- Use existing theme structure
+- No new components
+
+## Validation
+- Page fills full screen (no bottom gap)
+- Content renders cleanly
+- No layout regressions
