/* ===========================================================================
   TutorPro Online English — shared stylesheet for every static page.

   WHY THIS FILE EXISTS
   --------------------
   Each static page carried its own inline <style> block. They drifted apart
   and, worse, they had all drifted AWAY from the homepage: near-black
   backgrounds and white text, while the homepage is warm cream with purple
   ink. A parent clicking "Pricing" from the homepage landed somewhere that
   looked like a different company.

   One shared file means they cannot drift again, and it is cached once by the
   browser rather than re-downloaded inside every page's HTML.

   The tokens below are copied from src/styles.css so the static pages and the
   React app stay visually identical.
