🚀 Version 1.03 – Drag & Pan + Auto-Update
- 🖐️ Click-drag panning with smooth inertia (grab/grabbing cursor), plus automatic clamping to keep the image in view.
- 🧭 Smart bounds & margin: prevents empty edges on large zooms and allows a small pan margin for smaller images.
- 🧮 Refined transform pipeline: centered anchoring with
translate(-50%, -50%) scale(...) rotate(...) and absolute positioning for crisp motion. - ⌨️ Improved Double-Ctrl detection: debounced with keyup/keydown so holding Ctrl doesn’t trigger repeats or false positives.
- 🧹 Stronger cleanup: removes all
.zoom-overlay remnants and resets pan/zoom state on close. - 🖱️ Wheel-to-zoom preserved and background page scroll is blocked while the viewer is open.
- 🔁 Rotation & zoom limits kept: quick 90° rotate; zoom range remains 0.2×–5×.
- ⚡ Smoother interactions: disables transitions while dragging, restores them after; reduced layout jank.
- 🛠️ UI tweaks: toolbar uses fixed positioning for stability; minor polish on fade-in/out.
- 📦 Userscript metadata: added
@downloadURL and @updateURL for GreasyFork auto-updates. - 🐞 Misc fixes: prevents text selection during drag and tidies duplicate event paths.
