## Overview

This is a single-file, browser-based ad layout engine. A user supplies one ad brief; the engine derives a per-surface plan, and the renderer presents it across six ad formats. The README documents the stages and their responsibilities, but no source excerpts were provided, so the graph uses only those documented relationships; UI event details and internal call wiring remain unverified.

Main entry points: [`index.html`](https://github.com/harshithdarisa/adaptive-layout-engine/blob/main/index.html) (Priority admission)
