/*
  sign-pdf/sign-pdf.css
  ==================================
  Self-contained styles for the Sign PDF tool. Follows the same
  duplication pattern as every other tool (see upscaler.css's header
  comment) -- base diambil dari watermark-pdf.css (drop zone, field,
  preset group, editor canvas + drag handle, thumbnails, buttons,
  status, FAQ) karena Sign PDF memakai editor canvas drag yang sama
  persis. Tambahan khusus tool ini ada di bagian paling bawah: pad
  gambar tanda tangan (canvas) + tab mode (gambar tangan / upload
  gambar / ketik nama) + palet warna pena.
