Worked on the emscripten-core/emscripten repository to improve documentation accuracy by removing outdated references to the deprecated Large-Allocation HTTP header. Focused on aligning the documentation with current web standards and clarifying that browser support is now limited to Firefox, which helps reduce confusion for both developers and maintainers. Utilized technical writing and documentation skills, specifically working with reStructuredText, to ensure that the changes were clear and traceable for future maintenance. This update addressed issue #26370 and contributed to more reliable cross-browser guidance, supporting the ongoing maintainability and usability of the emscripten documentation for its user community.
