/* ==========================================================================
   1. RESET & SCROLLBAR STABILITY
   
   KEY DECISIONS:
   - html gets overflow-y: scroll to ALWAYS show scrollbar gutter.
     This prevents width jump when content goes from short to tall.
   - We use width: 100% everywhere, NEVER 100vw (which includes scrollbar).
   - No overflow on body — let html handle it.
   - Scrollbar is styled to be subtle and consistent.
