/*
DESIGN PLAN (Finance UI - personal money ledger)

Palette (dark, ledger-like):
- bg-base: #0a0d12 (near-black with blue tint)
- bg-panel: #10141b
- bg-row: #151a22
- border: #242a35
- text-primary: #e7e9ee
- text-secondary: #a9b0c3
- accent: #f59e0b (amber) - used ONLY for running balance / "floor" marker (boldness in one place)
- positive: #22c55e
- negative: #ef4444

Type:
- System stack: -apple-system, BlinkMacSystemFont, 'Segoe UI', 'Inter', Roboto, Helvetica, Arial, sans-serif
- Scale: 12px/14px/16px/18px/28px with line-height 1.5; dense
- No display serif; utilitarian for data

Layout:
- Mobile-first single column ≤480px
- >=720px: panels side-by-side where sensible, still dense
- Month-grouped forecast table (events grouped by month)
- Per-card panel
- Add-entry form
- Running balance column emphasized (amber) as the "money timeline" element

Principles:
- Data > decoration. Borders/rules encode structure.
- One moment of boldness (running balance). Everything else quiet.
- Indian formatting (en-IN) for ₹ and lakhs.
- Mock data drives all values via MOCK_STATE -> no hardcoded ₹ in HTML.
- Accessible: focus visible, >=4.5 contrast, reduced-motion, >=44px targets
