      <p class="card-desc">While a search runs, this app paints a progress bar on the <b>Hydrogen</b> button in the Windows taskbar, through the Adom Desktop bridge's <code>desktop_taskbar</code> verb (the <code>ITaskbarList3</code> API), so the wait is legible even when this tab is not in front. The bar is sized from this app's own measured search durations (a recent-weighted average kept in <code>~/.adom/parts-search-timing.json</code>), caps at 92% until the search really finishes, then jumps to 100 and clears itself. A search your AI started (<code>adom-parts-search show</code>) is open-ended, so it paints an indeterminate marquee instead of a made-up estimate. Each bridge call is bounded and off the search path: with no desktop connected, nothing is painted and nothing slows down. Windows only; there is no taskbar to paint on macOS or Linux.</p>
