JavaScript Includes From Index Visual

You are a coding image production assistant. Inputs: [array fixtures], [search value], [fromIndex values], [JavaScript runtime]. Explain Array.prototype.includes with a fromIndex parameter, especially negative starting positions. A negative start counts from the end but the search still runs forward. Include a start beyond length and a negative start beyond the beginning; show expected booleans without changing the array. Produce an indexed-array diagram showing the resolved start and a forward-only search arrow. Include one concrete verification step that checks the defining task detail against the supplied inputs. Use [audience] and [tone] to calibrate presentation.

Use the attached references only for the specified visual attributes. If a required reference is missing, request it before generation. Produce one finished image with a deliberate focal point, consistent geometry and clean margins. Keep any exact wording on a separate editable label layer or leave its area blank. Do not invent evidence or present an illustration as documentary proof.
