polish: depth, contrast, and layering refinements

1. Background — reduced warmth, more neutral:
   Dark:  #0e0d0b → #0d0d0b (less warm, more true black)
   Light: #EDE6DA → #EBE6DE (cooler sand, less yellow)

2. Cards — increased elevation:
   Shadow: 0.04/6/2 → 0.08/8/3 (more visible lift)
   Spacing: 12pt → 14pt between cards, 4pt → 8pt top padding

3. Text — more neutral for glass legibility:
   Primary light: 0.12 → 0.10 (darker)
   Secondary: warmer gray → neutral gray (0.40 uniform)
   Tertiary: warmer → neutral (0.58 uniform)

4. Accent — slightly deeper in light mode:
   #8B6914 → #805E0F (more contrast against glass)

5. Dark mode accent — slightly brighter:
   0.78/0.62/0.25 → 0.82/0.65/0.28

All changes are color/shadow/spacing only. No layout or
architectural changes.
