 - Permissions are requested at first launch (camera; storage on Android ≤ 9) and again when a feature needs one.
 - Downloads: https on allowed hosts via `DownloadManager` (session cookie forwarded); `data:` decoded natively; `blob:` read in-page and returned via `evaluateJavascript` polling (no JS interface). A document-start hook keeps blobs readable if the site revokes the URL immediately. Saved to Downloads, with a toast on completion.
-- Uploads: `<input type=file>` image fields offer the camera; `capture` opens it directly. Photos are saved to Pictures/Joykoo.
+- Uploads: `<input type=file>` image fields show an in-app "Tomar foto / Elegir de la galería" dialog (the system chooser hid the camera behind the gallery picker); `capture` opens the camera directly. If camera permission is denied, a dialog offers app Settings or the file picker. Photos are saved to Pictures/Joykoo.
 - In-page camera (`getUserMedia`) is granted to allowed hosts only, video only.
