/* ============================================================
   home.css
   Stitch "Obsidian Reserve" Home screen + the four-item bottom
   nav (Home · Learn · Market · Coach).

   Presentation only. Reuses the canonical --fl-* token layer from
   theme.css (surfaces, mint accent, display/label faces, radii).
   Loaded LAST so it wins the cascade for its own elements.

   Surface language (matches the approved Stitch reference):
     - Cards are DARK RAISED NAVY surfaces (surface-container family),
       NOT the older near-black #0f1010 panels.
     - Market card sits one step lighter for hierarchy.
     - Borders are subtle low-contrast white-alpha hairlines.
     - Card radius is the Stitch 12px, not the 16px app card radius.

   Rules:
     - Negative market values = red (--red-text)
     - Positive market values = mint (--fl-accent)
     - No fake data, no image cards, no marketing heroes.
