/* =============================================================================
   eBay Challenge v3 — shared styles

   Only the substrate that every page uses: colors, fonts, masthead, snapshot
   strip, colophon footer, container, buttons, and utility classes.

   Page-specific CSS (dashboards, tables, forms) lives per-page for now — will
   move here as patterns stabilise.
