/* ============================================================================
   Dr. Tushar Deshpande — site theme
   Deep navy ground, teal action colour, gold hairlines, warm paper surface.
   No external fonts, no CSS framework, no runtime dependencies.

   Density note: the brief asked for each page's main content to sit inside
   roughly one scrolling window, with larger sub-headings and larger figures.
   Section padding is therefore tighter than the original build while the type
   scale for h3 / sub-headings / captions is a step larger.
