 Static type checking for `.wrn` declarations, props, state, outputs, functions, stores, and generated virtual TypeScript files.
 
 The package is compiler tooling rather than a browser UI package, so its public kit consists of programmatic typecheck helpers and diagnostics.
+
+View attribute `{t:key}` segments are translation markers, not TypeScript expressions. Ordinary expressions in the same attribute remain typechecked. Inline event bindings accept statement lists, with `event.currentTarget` typed as the bound HTML/SVG element. Nullable DOM queries still require normal guards.
