Please address the comments from this code review:

## Overall Comments
- In the new color range picker HTML, the injected Kaspersky script and stylesheet URLs look unrelated to the tool and could introduce instability or security warnings; consider removing those external resources and hosting any required assets locally or via trusted CDNs.
- In the image analysis loop of the color range picker (`if (a < 255) continue;;`), the double semicolon is a minor typo and the alpha-threshold logic currently skips any semi-transparent pixel; if your intent is only to exclude fully transparent areas, consider changing the condition to something like `if (a === 0) continue;` for clarity.

**🚨 issue (security):** Avoid committing third-party injected Kaspersky script/CSS for a local devtool page.

These Kaspersky-hosted resources appear to be AV-injected rather than intentional. They introduce unnecessary external dependencies and potential tracking, so please remove them and keep only locally controlled assets on this page.

**suggestion:** Consider using the modern Clipboard API instead of the deprecated `document.execCommand('copy')`.

`execCommand('copy')` is deprecated and may not work reliably in all browsers. Prefer `navigator.clipboard.writeText(text)` when available, with a fallback to this textarea approach and explicit handling of clipboard/permission failures.

```suggestion
  async function copyText(text, btn) {
    const fallbackCopy = () => {
      const textarea = document.createElement('textarea');
      textarea.value = text;
      textarea.style.position = 'fixed';
      textarea.style.top = '-9999px';
      document.body.appendChild(textarea);
      textarea.focus();
      textarea.select();
      let success = false;
      try {
        success = document.execCommand('copy');
      } catch (err) {
        success = false;
      }
      document.body.removeChild(textarea);
      return success;
    };

    let copied = false;

    if (navigator.clipboard && navigator.clipboard.writeText) {
      try {
        await navigator.clipboard.writeText(text);
        copied = true;
      } catch (err) {
        // fall back to textarea method
        copied = fallbackCopy();
      }
    } else {
      copied = fallbackCopy();
    }

    if (copied) {
      showToast(text);
    } else {
      console.error('Failed to copy text to clipboard:', text);
      showToast('Failed to copy to clipboard');
    }
  }
```
