Low and mid fidelity

Low fidelity draws a clean grey wireframe: outlines, crossed image boxes and grey lines in place of body copy. Mid fidelity shows real text, filled primary buttons and your accent colour.

Switch it from the Theme panel (nothing selected). Every layer restyles at once and nothing you typed is lost.

Mid fidelity is part of Pro. Free accounts can try it: frames and exports show a faint PRO PREVIEW watermark until you upgrade, and it disappears when you switch back to low.
