One copy instead of two:

Suggested change

	image_bytes = buffer.getvalue()
	# Create and return response with appropriate headers
	return Response(
	to_js(image_bytes).buffer,
	headers={
	"Content-Type": content_type,
	"Cache-Control": "public, max-age=3600",
	},
	)
	image_bytes = create_proxy(buffer.getvalue())
	jsbuffer = image_bytes.getBuffer()
	try:
	# Create and return response with appropriate headers
	return Response(
	jsbuffer.data,
	headers={
	"Content-Type": content_type,
	"Cache-Control": "public, max-age=3600",
	},
	)
	finally:
	image_bytes.destroy()
	jsbuffer.release()

What if we move this into it's own .html file and do

  return Response(endpoints.read_text(), headers={"Content-Type": "text/html"})
