/**
 * tap-targets.ts — WCAG 2.5.5 / Apple 44pt tap-target audit module.
 *
 * Two input modes:
 *   url mode      — renders a page with Playwright, collects every interactive
 *                   element's getBoundingClientRect w/h via page.evaluate.
 *   snapshot mode — accepts a caller-supplied elements[] array (no browser needed).
 *
 * For each element: pass = (w >= minSize && h >= minSize). Failures include a
 * concrete fix suggestion. Results sorted worst-first (largest combined deficit).
