Audit context

robots.txt is available. 11 of 11 tracked AI bots are not blocked. Declared sitemaps: 0. The homepage exposes Schema.org types Product, SoftwareApplication, Review, FAQPage; 8 OpenGraph tags were found and markup completeness is 90%.

The Google Lighthouse measurement is still collecting. Once complete, performance, accessibility, technical quality, SEO, and experimental browser-agent signals will be added with a limited weight.
