-// ====================
-// The purpose of this project is to
-// make a reader so that I can read
-// novels even faster than my already
-// amazing speed.(200k words/day) to (300k words/day)
-//
-// Rsearch objective:
-// Terminal: RSVP (Rapid Serial Visual Presentation)
-//
-// Project Name: fastAsFKReader(FAFK)
-// Author : Aakarsh Kashyap
-// [ 2026-06-17 ]
-// ====================
-
-// Steps
-//
-// 1. Get to the raw mode
-// 2. Get cursor to center of the terminal
-// 3. Parse the whole file into the memory and save it into a vector
-// of strings.
-// 4. Figure out the central letter of the string
-// 5. Print that word with the central letter coloured
-// 6. We will take a timer args which will make word rendering fast or slow but
-// it's fine for now
-// 7. The size of the word is smt dependent on user terminal zoomin we will not
-// try to render bigger font or anything
-// 8. End of the program.

-/* CONCLUSION */
-// Experiment have failed. I do not see any particular increase int my
-// reading speed, infact it has become difficult to
-// keep previous context in mind
-// There must be something else going on in that reel
-// I will try to ask about it from sei or shashy maybe there is a
-// better way
