   PRATHAMSATYA WEBSITE — MAIN STYLESHEET
   =========================================================================
   This file contains the design system (colors, fonts, spacing) and the
   base styles for every component on the site. Phone/tablet/desktop
   breakpoints live in responsive.css. Animation keyframes live in
   animations.css. Load order in the HTML is: style.css, responsive.css,
   animations.css.

   HOW TO RE-COLOR THE WHOLE SITE:
   Scroll to the ":root" block right below this comment and change the
   hex color values. Every component on every page reads its colors from
   these variables, so editing them here updates the entire website.
