  • Charging and completion are announced in a polite live region.
  • The control includes visible hold instructions and a strong focus indicator.

Integration plan

  1. Copy the standalone HTML and scoped CSS into an isolated page.
  2. Adapt plasma color, electric color, surface color, label color through the Inspector.
  3. Connect the defensive JavaScript, then test every control with a keyboard.
  4. Review the result at 375, 768, 1024, and 1440 pixels before shipping.
