Session summary: ### Commits pushed to PR #16 (feat/backend-status-indicator) **fix: wall-aware ghost movement, gameLoop guard, spawn grace period, duplicate listener** - Duplicate `keyup` listener removed (was registering multiple times on restart) - RAF guard (`rafId`) prevents stacked game loops on restart/guest/login - Spawn grace period (90 frames ≈ 1.5s) stops ghosts instantly killing players on spawn - All entry points (`loginBtn`, `guestBtn`, `restartBtn`) now call `startGame()` instead of `gameLoop()`    date: 2026-03-09T06:45:59.871073+00:00   source: joekookerbot   id: chat-history-session-19   title: Session 19 — Pacman BFS Pathfinding, Goggles Power-up & Bug Fixes   tags: ["joekookerbot", "chat-history"]
