This commit includes all the needed workarounds and most changes from the main branch for everything to work, like: * removing empty lines in raw HTML that break output * read .browserslistrc, CSS variables from disk instead of duplicating it * using Hugo mounts * using Hugo for the docs CSS/JS * move ToC Sass code to a separate file while adapting it for Hugo Thus, this patch makes our npm scripts faster since lint runs on one step and there's no separate docs assets processing.
