 - Keep doc comments and comments simple, one line, straightforward, and unbloated.
 - Prefer implementing functionality in existing files unless it is a new logical component. Avoid creating many small files.
 - Prefer `impl` blocks over standalone functions: place functionality as methods or associated functions on the relevant type, extending the type's existing `impl` block instead of creating a duplicate one in another file.
-- Prefer generic parameters with a `where` clause over argument-position `impl Trait` in function signatures (`fn extend<I>(&mut self, elements: I) where I: IntoIterator<Item = AnyElement>`); return-position `impl Trait` stays.
+- Always use generic parameters with a `where` clause instead of argument-position `impl Trait` in function signatures (`fn extend<I>(&mut self, elements: I) where I: IntoIterator<Item = AnyElement>`); return-position `impl Trait` stays.
 - Do not wrap dependency APIs in project structs or pass-through helper functions; call their methods directly where needed. Extract a helper only when it holds real logic that is used in more than one place.
 - Bind a global store handle to a local before using it (`let theme = Theme::global(cx);` then `theme.…`) instead of chaining `::global(cx)` inline.
 - Avoid using functions that panic like `unwrap()`; instead use mechanisms like `?` to propagate errors.
