/* ============================================================================
   Accelerating AI - "Signal" design system (WordPress theme stylesheet)
   Ported faithfully from the Claude Design handoff:
     tokens/{colors,typography,spacing,fonts}.css + base.css
     components/{Button,Badge,Input,IconTile}
     ui_kits/relaunch-site/app.css  (the "Signal" layout)
   Direction: editorial, technical, credible. Dark stage + electric-blue accent,
   numbered section indices, registration-mark corner ticks, travelling signal
   line, big confident Gotham, generous full-bleed imagery.
   Self-contained - no build step, no framework.
