Dashed-border dropzone for embedded upload contexts (settings → upload avatar, new transfer modal). Idle → neutral. Drag accept → yellow border + tinted bg. Drag reject → red border + tinted bg. Always shows the "or select" link as a click target.

Triggered when the user drags files anywhere in the app, not just over a dropzone. Yellow-tinted scrim with a 3px dashed border, big cloud glyph centered. The underlying UI dims but stays visible through the backdrop blur.

Once the upload starts, the dropzone collapses into a list of rows. Each row shows file glyph, name, progress bar, percent / rate, and a cancel button. Completed rows turn green; failed turn red and keep their cancel as a "remove" affordance.
