New "Scan image" button in the input pane header: - Opens the phone's rear camera (capture=environment) or a desktop file picker via a hidden <input type="file">. - On image selected, lazy-imports tesseract.js from esm.sh — no bundling, no Docker image growth. - Language follows the "From" dropdown (ISO 639-2 mapping for the 30 currently-supported languages). "Auto-detect" loads the eng+por+deu+nld pack and lets tesseract pick. - Progress status renders below the input (engine load → OCR percentage → "done in Xs"). - Result replaces the editor contents; existing vim bindings, Shift-H/L nav, Ctrl-Enter translate all keep working. First scan triggers a ~5 MB Tesseract WASM download plus the chosen language pack (~3-10 MB). Cached by the browser after.
