// Tests for shared/logo.js — turns the .app-header__logo SVG into a
// link to the project landing (or deployment root). Mounts at
// DOMContentLoaded across every tool's bundle.
//
// Strategy: serve any tool's compiled HTML at multiple URL paths via a
// tiny in-process HTTP server, so we can verify the wrapping anchor's
// href reflects the URL the page was loaded from.
