/* ═══════════════════════════════════════════════════════════
   AI & JOBS LAB — page-specific styles. Editorial chrome
   inherits from main.css; this file adds the search, occupation
   card, scatter, bump chart, empirical-reality grid, and
   compare-two-jobs view.

   Two accent colors are used here: the existing red --accent
   for the AI exposure axis, and --accent-2 (a deep editorial
   blue, defined in main.css) for robotics. Per CLAUDE.md
   convention, no other new accent colors.
