This change includes: - Adding `sass` as a dev dependency. - Introducing a custom SCSS file to override KaTeX variables and disable TTF/WOFF fonts, relying solely on WOFF2 for embedding. - Adjusting the Vite configuration to resolve `katex-fonts` alias and inject SCSS variables. * fix: LaTeX processing within blockquotes * webui: update webui build output --------- Co-authored-by: Aleksander Grygier <aleksander.grygier@gmail.com>
