Enterprise-Grade Detailed Feature Comparison Table Prompt

Act as an Enterprise B2B Frontend Developer. Create an advanced, highly readable, and deeply mobile-responsive feature comparison matrix utilizing Tailwind CSS. The DOM structure must programmatically parse and accept a complex JSON input [FEATURES_JSON] containing nested feature categories, specific feature names, and their boolean/text availability across 4 distinct SaaS tiers. If the [STICKY_HEADER_BOOL] flag evaluates to true, the top table row containing the tier names and pricing must permanently affix to the top of the viewport upon scroll utilizing Tailwind's `sticky top-0 z-10` utility classes, accompanied by a subtle drop shadow. Implement distinct, accessible 'Check' (green) and 'Dash' (gray) SVG icons to denote feature availability. Crucially, solve the mobile table problem: on viewports smaller than `md`, gracefully transform the rigid matrix into an accordion layout or a horizontally scrollable container with a visual gradient cue to maintain strict data readability. Apply a minimal, trustworthy corporate aesthetic utilizing subtle slate/gray borders and zebra-striping for rows.
