Performance

Performance should be visible as a first-class docs topic, not only an advanced subtopic.

What this page should cover

• the major runtime costs in introspection-heavy code
• where ginext is trying to improve performance
• how to profile real applications
• how overlays or generated surfaces can affect hot paths
• where users should look before reaching for low-level optimizations

This page can then link deeper into advanced implementation material when the site grows.
