 - Per-word confidence filter (≥ 60) drops the low-confidence noise Tesseract still emits. Re-assembles lines from kept words; status line reports how many words were dropped.
 - Crop & rotate modal between image pick and OCR. After choosing an image, a modal pops up with cropperjs's drag-handle crop UI and Rotate left / Rotate right / Reset buttons. EXIF orientation is honoured automatically. Cancel / `Esc` / clicking the backdrop aborts; `Enter` accepts. Library lazy-loaded from esm.sh (no bundling).
 
+### Changed
+- "Scan image" button replaced with a 📷 floating action button at the bottom-right of the viewport (was a small button in the input pane header). Mobile thumb-friendly, doesn't crowd the input label.
+- Crop modal has inner padding so cropperjs's corner handles stay away from the screen's right/bottom edges — fixes the bottom-right resize handle triggering Android's edge-swipe back gesture. Also respects iOS safe-area insets.
+
 ### Fixed
 - "Hot: …" status no longer claims "unloads in X" when the server's `keep_alive` is `-1` (Ollama returns an absurd year-4001 `expires_at`). Threshold: any expiry >7 days drops the suffix and just shows the model name.
