📸 CAPTURE, FOUR WAYS
• Selected area — drag a box around any part of the page
• Element — hover and click one card, nav bar, or modal, cropped cleanly to its edges
• Visible part — what's on screen, one click
• Full page — the whole scrolling page, stitched into a single image
• Delay timer — count down before capture to catch tooltips, dropdowns, and hover states
