Start with content and integrations#
- Use appropriately composed images and avoid uploading unnecessary duplicate media.
- Keep the initial page focused instead of stacking many autoplay banners.
- Review apps and third-party scripts before adding more tracking or widgets.
- Test the actual published configuration on mobile and desktop.
- Keep product/gallery/media alt text and essential interactions intact while optimizing.
Theme behavior#
The code uses responsive image helpers and conditional assets in multiple places. The featured-products carousel can defer offscreen instance initialization; this does not mean the Swiper dependency is absent from initial loading. The gallery viewer library can load on first relevant interaction. These implementation choices are not a promise of a particular Lighthouse score.
Measure consistently#
Use comparable routes, devices and throttling settings. Repeat measurements and record warnings. A password page, extension, preview environment or unresolved request can make a score misleading. Public performance acceptance for the current release is still pending.
