    SLATEARENA DESIGN SYSTEM NOTES

    This CSS file is intentionally commented as a handoff artifact.
    Treat these notes like embedded markdown for future developers, agents, and designers.

    Product Feel:
    - Premium sports intelligence platform.
    - Dense enough for bettors/DFS players, but not chaotic.
    - Should feel closer to a trading desk/community arena than a marketing template.

    Visual Rules:
    - Cards and panels max out at 8px radius.
    - Avoid decorative blobs, oversized hero art, and generic gradient SaaS styling.
    - Green/blue indicate positive edge or action.
    - Amber indicates gated/locked/caution.
    - Red indicates negative movement/risk.
    - Text must remain readable on mobile; do not scale typography by viewport width.

    Future Rebuild:
    - These tokens should become shared app tokens in React/Next/Vite.
    - Component families to preserve: shell, board rows, edge panel, pricing cards,
      community pulse, lead form, trust/legal note.
