/* =============================================================================
   TILES.CSS — Index Tile Component (Market Pulse / Landing Page)
   AI Supply Chain Dashboard
   Created: 2025-02-27

   PURPOSE: The animated index tiles (SPY, QQQ, DIA etc.) with MA stack ladder
   and trend score are exclusive to index.html. Extracted here to keep index.html
   lean for the Vite migration.

   COMPONENTS:
   - .index-tile          Clickable market tile card
   - .change-badge        % change pill (top-right)
   - .price-text          Large price display
   - .stack-row           MA stack ladder row
   - .ext-bar             Extended hours strip
   - .vol-tag             Volume ratio badge
   - .cat-section         Category group wrapper
   - .guide-wrapper       Score guide tooltip
   - .modal-overlay       TradingView chart modal
   - .dash-btn            "View full dashboard" CTA button

   USAGE: @import './tiles.css'; in index.html ONLY.
   Also imports: base.css, scores.css (for score-N classes on trend-badge).

   REVERT: Copy all rules below back into index.html's <style> tag.
