Description

Is your feature request related to a problem? Please describe.

Currently, JPEG XL (.jxl) files cannot be displayed on the web or in the iOS app.

Describe the solution you'd like

Support for JXL files would be great, especially if the browser already supports displaying them anyway, why would it not display them but download them?

Research direction

Start by reviewing the viewer's existing handling for media formats that browsers cannot display inline, then check the linked Nextcloud iOS and Photos issues for related decisions. Confirm current browser support for JPEG XL and identify the viewer entry points involved. Done means JXL files display in the web viewer as intended, with any iOS work aligned with the linked issue.
