✨ add Nisse info panel with work log (Issue #9)

Clicking a Nisse opens a top-left panel showing name, AI status,
energy bar, active job, job priority buttons, and a live work log
(last 10 of 20 runtime-only entries). Closes via ESC, ✕, or clicking
another Nisse. Dynamic parts (status/energy/job/log) refresh each
frame without rebuilding the full group.

 ## [Unreleased]
 
+### Added
+- **Nisse Info Panel** (Issue #9): clicking a Nisse opens a top-left panel with name, AI status, energy bar, active job, job priority buttons, and a live work log (last 10 of 20 runtime entries); closes with ESC, ✕ button, or by clicking another Nisse
+- Work log tracks: walking to job, hauling to stockpile, going to sleep, waking up, chopped/mined/farmed results, deposited at stockpile
+- **ESC Menu** (Issue #7): pressing ESC when no overlay is open shows a pause menu with Save Game, Load Game, Settings (placeholder), and New Game; New Game requires confirmation before wiping the save
+- ESC key now follows a priority stack: confirmation dialog → context menu → build menu → villager panel → Nisse info panel → ESC menu → (build/farm mode handled by their systems) → open ESC menu
+
+### Added
+- **F3 Debug View**: toggleable overlay showing FPS, tile type and contents under the cursor, Nisse count by AI state, active jobs by type, and pathfinding visualization (cyan lines in world space)
+
 ### Fixed
 - Nisse now clear the FOREST/ROCK tile after harvesting, opening paths to deeper resources
 - Nisse no longer get stuck idle after depositing items at the stockpile
@@ -20,8 +29,12 @@ Format follows [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).
 - Villagers are now called **Nisse** throughout the UI (panel, controls hint, stockpile display, context menu, spawn message)
 
 ### Added
-- Scroll wheel now zooms toward the mouse cursor position instead of the screen center
+- Scroll wheel zooms toward the mouse cursor position (zoom-to-mouse), correctly accounting for Phaser's center-based zoom model
 - Middle mouse button held: pan the camera by dragging
+- Test environment at `/test.html` with `ZoomTestScene` (Phaser default) and `ZoomMouseScene` (zoom-to-mouse) for camera behaviour analysis; file-logging via Vite middleware to `game-test.log`
+
+### Fixed
+- `getCenterWorld()` in `CameraSystem` returned wrong world coordinates at zoom ≠ 1; corrected from `scrollX + width/(2·zoom)` to `scrollX + width/2`
 - Right-click context menu: suppresses browser default, shows Build and Nisse actions in the game world
 - Initial project setup: Phaser 3 + TypeScript + Vite
 - Core scenes: `BootScene`, `GameScene`, `UIScene`
