When to use it

A playful reveal: a gift, a reward, a hidden picture.

When not to

Hiding text people must read, or coupon and discount copy.

Working with an AI agent

Every component ships agent-ready metadata. An example instruction for this one:

Matte paper register (graphite or clay wax on cream; #1C1B18 / #F4F1EA). Edit --sf-* tokens; replace the .sf-pic SVG; BRUSH and DONE set the brush and the auto-clear share.

Safe to edit

  • --sf-* tokens
  • .sf-pic SVG drawing
  • BRUSH, DONE

Keep intact

  • IIFE + prefix, reduced-motion, visibilitychange, theme hook, demo-v1

Known limitations

  • Resizing re-covers a part-scratched card
