/* ==========================================================================
   Vantello site styles
   --------------------------------------------------------------------------
   Replaces the per-page <style> blocks that previously drove the responsive
   layout by substring-matching inline style attributes (e.g.
   [style*="repeat(3, 1fr)"]). That approach broke silently whenever an inline
   style was reformatted, so layout is now driven by classes.

   Palette is anchored to the approved logo colours:
     Deep Navy #0B2D4D   Electric Blue #2D7FF9   White #FFFFFF
