summary: List the interactive elements of an HTML page with stable CSS selectors
description: 'Reduces an HTML document to the elements an agent can act on: links with href, buttons, inputs (not type=hidden), selects, textareas, [role], [onclick], contenteditable, each with tag, type, role, best-effort accessible name (including label associations) and a CSS selector that matches exactly that element, preferring a stable id, then a data-testid-style attribute, name, aria-label, then a structural path anchored at the nearest stable id. Skips elements hidden by attributes (hidden, aria-hidden, inert, inline display:none or visibility:hidden, closed details, template/noscript) and collapses repeated identical controls. Static HTML only: no scripts run, stylesheets are not applied, and visibility from CSS classes is unknown.
