=== RENDERED AUDIT: FIRST 240 LINES ===
     1	// Accessibility check for the full audit, drawn the way a browser draws it.
     2	//
     3	// The Accessibility page tool (public/accessibility-audit.html) runs its checks on the page as Chrome
     4	// draws it with the site's own CSS: it measures colour contrast and control edges, and it knows which
     5	// text the CSS hides. lib/accessibility-checker.js reads the raw HTML only. This module runs the page
     6	// tool's own check (checkA11y) in one shared headless Chrome on the HTML the full audit already fetched,
     7	// so /api/audit-full gives customers the same answers as the page tool. Any failure (Chrome missing,
     8	// time-out, crash) rejects, and the caller falls back to lib/accessibility-checker.js.
     9	//
    10	// Every page is first loaded with its own scripts running, in Chrome's sandbox, and a copy of the finished
    11	// page is audited (renderWithScripts), so the audit sees what visitors see after the page loads (content,
    12	// colours and banners added by scripts, and pages built entirely by JavaScript). A bot-check page is never
    13	// run with scripts: a site that blocks checkers is respected, not worked around. If the page cannot be loaded
    14	// that way (error status, bot-check, or it comes back almost empty), the fetched HTML is audited instead.
    15	//
    16	// Safety: Chrome runs with its sandbox ON (it runs other sites' scripts). Every request Chrome makes (stylesheets go through the app's own guarded fetch; images and
    17	// fonts the audited page asks for) is checked first and blocked if it points at a private, loopback or
    18	// link-local address, so an audited page cannot make the server call itself or its network. The tool
