+Pac-Man CRT (temp)
+
+- Location: .openagent/tmp/pacman-crt
+- Run: open index.html in a browser (double-click or `open .openagent/tmp/pacman-crt/index.html` on macOS)
+- Stack: HTML5 Canvas + JavaScript + CSS-only CRT effects
+- Notes:
+  - Grid-aligned movement, pellets, power pellets, four ghosts with chase/scatter/frightened.
+  - Simplified ghost AI: intersection heuristic toward a target; frightened is random; mode timer cycles scatter/chase.
+  - No external assets required (WebAudio beeps for sfx).
+  - Pure static (no build tooling). If desired, serve with any static server.

+# Context: Pac-Man CRT (temporary)
+
+Purpose
+- HTML5 + JS Pac-like with old-school CRT look for local demo purposes. Lives under .openagent/tmp/pacman-crt.
+
+Key files
+- index.html: entry point
+- style.css: CRT screen aesthetics (scanlines, vignette, warp)
+- game.js: tilemap, game loop, entity logic, simplified AI, WebAudio beeps
+
+Known risks / notes
+- Ghost AI simplified vs. original arcade; timings/behaviors are approximate.
+- Collision edge cases may differ from the original hardware.
+- Power pellet and frightened timers are intentionally short for quick demos.
+- CRT effect is CSS-based; appearance varies slightly across browsers/monitors.
+
+Maintenance
+- Self-contained, static; no build step. Update this context if files change.
