So the main valid methods would be image-based. The guide should focus on generating images with the desired font from online tools.

Including screenshots or examples would be helpful, but since this is text-based, I'll describe the steps clearly. Also, mention the importance of high-quality images to avoid pixelation on VK.

body font-family: 'Deia', sans-serif;

I should structure the guide step-by-step, starting with the easiest method first, which would be using online generators. Then, for those wanting more control, software options. Also, mention any possible CSS methods if applicable, but note limitations.

Advanced techniques might include using custom HTML/CSS if the user has a VK blog or page, but standard profiles probably can't. So maybe that section is minimal here.

Also, note that when creating text images, it's important to have a clear background and font color contrast, and maybe add effects like shadows for readability on VK's interface.
