94-110: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winUse a named options object for the synthetic line helper.
linenow takes three same-typed numeric arguments, andtoCharappears beforefromChar. A caller can swap the offsets without a type error. Change the helper and its two call sites to use an object withfromChar,toChar, andwidth.Proposed refactor
- const line = (toChar: number, fromChar: number, width: number) => ({ + const line = ({ + toChar, + fromChar, + width, + }: { toChar: number; fromChar: number; width: number }) => ({ ... - lines: [line(18, 0, 370), line(36, 18, 380)], + lines: [ + line({ toChar: 18, fromChar: 0, width: 370 }), + line({ toChar: 36, fromChar: 18, width: 380 }), + ],As per coding guidelines, use named
options,args, orparamsobjects for three or more or interchangeable arguments.🤖 Prompt for AI Agents

Trace type mismatches to their source rather than casting at the consumer.
Do not annotate or provide explicit type arguments when the compiler can infer them; let inference flow and narrow at boundaries.
Validate large-union object literals with as const satisfies T rather than a : T annotation.

Correct the explicit word-spacing budget for justified first lines with positive indentation. The painter now uses the same available content width as measurement, preventing tab-bearing lines from extending into the right margin.
Adds regression coverage for positive first-line indents and updates the existing synthetic measurement fixture.
