/* =====================================================================
   Scroll Expansion Hero Polish
   Native Razor Pages / CSS / JavaScript tuning inspired by the 21st.dev
   ScrollExpandMedia behavior.

   Goals:
   - Keep the existing Evorix hero markup/assets.
   - Make the expansion feel controlled, smooth, and intentional.
   - Avoid the old 250svh runway feeling.
   - Use a wheel/touch progress engine like the original React component.
   - Keep the ripple background and footer ripple from the previous patch.
