• refactored logic as much as posibile to get rid of unnecessary array mapping / filtering or if else statements, to improve load time
• removed PreviewPrompt to reduce logic and added simple span with needed functionality (should behave the same)

visually it improves with about 1 sec load, the small rectangle still shows up but we can't really use dangerously set html and not have that small flickering
