HTTP Security Headers — Security Policies

This project provides a comprehensive web development checklist designed to verify the production readiness of websites before they are launched. It serves as a technical audit framework that guides developers through a systematic, manual validation process to ensure that all quality, performance, and accessibility standards are met. The checklist distinguishes itself through a hierarchical taxonomy that organizes complex technical requirements into logical domains, such as security, performance, and semantic structure. By utilizing a progressive enhancement methodology, it encourages developers to prioritize core functionality and universal accessibility, ensuring that sites remain robust and usable across diverse environments. The framework covers a broad range of essential implementation areas, including search engine optimization, asset management, and the configuration of browser-level security protocols. It also provides guidance on optimizing document metadata, managing web fonts, and refining code to improve responsiveness and load times.
