Feature: Standardize HTML class attribute naming (className → class)

Increasing Access

Making the code style consistent helps keep the project easier to read and understand, especially for new contributors. Right now, some parts of the code use className and others use class. Sticking to class everywhere follows Preact’s best practices and standard HTML, which makes things simpler and less confusing for everyone.

Feature request details

Description

This is a code quality improvement to standardize the use of HTML class attributes throughout the codebase.

Current Issue

The codebase inconsistently uses both className and class attributes. Some files use class, others use className, and some mix both within the same file.

Proposed Solution

Replace all instances of className with class throughout the codebase to maintain consistency with Preact best practices.
