Can you explain why those changes improve accessibility?

Using fill('color') on shapes (e.g.
doc.rect(100, 100, 300, 200).fill('orange')

results in an accessibility parsing error:
“Error while parsing PDF Document (Operator 'cs' not allowed in this current state…)” (see attached report).

To resolve this, I switched to an explicit color-setting approach, which eliminates the error and passes accessibility checks:

doc.fillColor('orange')
   .rect(100, 100, 300, 200)
   .fill();

Similarly, using stroke('color'):

doc
  .lineWidth(15)
  .rect(100, 100, 300, 200)
  .stroke('orange');

triggers a parsing error:
“Error while parsing PDF Document (Operator 'CS' not allowed in this current state…)”.

This is fixed by explicitly setting the stroke color before stroking:

doc
  .lineWidth(15)
  .strokeColor('orange')
  .rect(100, 100, 300, 200)
  .stroke();

The updated approach resolves the accessibility issues and has been verified with accessibility testing tools.
