/* ==========================================================================
   Aurena Showcase — stylesheet
   Extracted from the previously inline styles in index.html.
   Organised as: design tokens → base/reset → keyframes → layout → components
   → section-specific pieces. Reusable classes are favoured over one-offs.
   Note: hover effects are driven by `style-hover` attributes in index.html,
   which the support.js runtime compiles into real :hover rules — so they are
   intentionally NOT duplicated here.
