Prompt

A busy-state button with diagonal barber-pole stripes: alternating 12px bands of #6366f1 and #4f46e5 at -45 degrees, background-size 34px so the bands tile without a seam, scrolling sideways every 0.8s. White 14px semibold text, 8px radius, 13px by 26px padding, cursor progress, 90% opacity (100% on hover). Meant to be disabled while a task runs. Focus 2px indigo outline.
