🎉 COMPLETE SUMMARY: Dynamic Auto-Refresh Implementation

✅ TASK COMPLETED

Tombol "🔄 Refresh Origin" telah DIHAPUS dan sistem automatic real-time sudah aktif untuk menjaga posisi panel tetap di tengah saat Chrome di-zoom.

📋 PERUBAHAN KUNCI

1️⃣ Tombol Dihapus

File: js/frame/studiopose.js (Line 254)

❌ DIHAPUS: <button id="refreshCenterOriginBtn" onclick="refreshCenterOrigin()">🔄 Refresh Origin</button>

✅ HANYA TERSISA: Checkbox "Pusatkan Origin (0,0) ke Pojok Atas Kiri"

2️⃣ Sistem Otomatis Aktif

File: js/frame/studiopose.js (Line 582-584)

if (typeof initZoomDetection === 'function') {
    initZoomDetection();
    console.log('✅ Zoom detection initialized - akan follow Chrome zoom 25%-500%');
}

✅ AUTOMATIC: Dipanggil saat iframe load
✅ REAL-TIME: Monitor zoom setiap 100ms
✅ DYNAMIC: Update posisi panel otomatis

🎯 CARA KERJA

Chrome Zoom Change (Ctrl++, Ctrl+-, Ctrl+0)
           ↓
Browser zoom level berubah (25% - 500%)
           ↓
initZoomDetection() detect perubahan (setiap 100ms)
           ↓
updateCenterOriginTransform() dipanggil
           ↓
Panel position updated ke center viewport
           ↓
User lihat: PANEL TETAP DI TENGAH ✅
(NO MANUAL ACTION NEEDED)

📊 BEFORE vs AFTER

Feature	Sebelum	Sesudah
Panel Reset	Button click manual	Otomatis real-time
User Effort	Click button tiap zoom	Zero action
Deteksi Zoom	Manual trigger	Every 100ms auto
Visual UX	Bisa bergeser → perlu refresh	Smooth & responsive
Keyboard Shortcut	Ada	Masih ada (Ctrl+Alt+R)

🔧 TECHNICAL DETAILS

API: window.outerWidth vs window.innerWidth

Detects zoom level (0.25 = 25%, 1 = 100%, 2 = 200%, dst)

Detection Frequency: 100ms interval

Responsive tapi tidak memakan CPU banyak

Supported Zoom Range: 25% - 500%

Covers typical browser zoom usage

Position Formula:

transform: translate(calc(-50% - offsetX), calc(-50% - offsetY)) scale(currentZoom);

calc() allows mixing % (responsive) + px (centering)
scale() maintain internal zoom level
