/* ==========================================================================
   Joshua Terrell — Artist & Photographer
   Stylesheet
   --------------------------------------------------------------------------
   Design system: flat / material-influenced surfaces with subtle elevation.
   Palette is built around a single blue accent on a white canvas, warmed up
   with a serif display face so the site reads as a working artist's studio
   rather than a generic software product.
   No external fonts or libraries are used — everything below relies on
   system font stacks and hand-written CSS/SVG for a fast first paint.
