Case contract

Input [word widths, width, cap lines, cap width, gap, indent]. With a drop cap its first letter moves into the cap (first word loses one unit) and the first cap-lines lines are narrowed by cap width + gap; the first-line indent applies only without a cap. Greedy fill with unit spaces; a word too wide for an empty line is set alone. Return [[words on line, used width]].

Why this case matters

Line breaking decides where paragraphs wrap on screen and in print; a wrong decision point shifts every following line.

One recorded failure

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.

Boundary fixture	Actual	Expected	Outcome
regression: cap gutter	`[[1, 5], [1, 6], [3, 7]]`	`[[1, 5], [1, 6], [2, 5], [1, 1]]`	Failed
