Support fillStyleId

Resources:

• Use getStyleById() to get a paint style (reference)
• PaintStyle API

Thoughts:

• Probably not much use in HTML + inline CSS
• For JS + inline CSS, we can create a string variable from the paint style, then use it whenever the color needs to be used. For example:

const blue = "#235EE7";
// inside the component...
<div style={{ color: blue, /* other styles */}}>Title</div>

• For JS/HTML + Tailwind CSS, we can add the colors into tailwind.config.js:

module.exports = {
  theme: {
    colors: {
      'blue': '#235EE7',
    },
  },
}
