Leetcode 1618. Maximum Font to Fit a Sentence in a Screen

Given a screen width and height, a sentence (words separated by spaces), and a font-size-dependent character width/line height model, find the largest integer font size that lets you fit the whole sentence on the screen without breaking words. This requires a feasibility check by greedily simulating word wrapping for a candidate size and using binary search (or monotonic search) over font sizes to maximize it.
