/* =================================================================
   agent-fluid.css — June 2026 agent chat rebuild
   One coherent dark cascade (the previous file layered three themes:
   cream → light chat-first → dark; only the dark one rendered).
   Loaded after styles.css; uses #agentLab for high specificity to
   beat the legacy body[data-ui-route="agent"] chain.

   Structure:
     1. Design tokens (base/light values — kept for the a11y contrast
        lint in test/a11y/color-contrast.test.js; the dark shell block
        below overrides them for the live UI)
     2. Skip link
     3. Section reset + retro-background wipe
     4. Dark chat-first shell (live tokens)
     5. Components (single pass, no override wars)
     6. Keyframes, focus, reduced-motion, responsive
