Summary

Closes #13.

Replaces the icon-only placeholder inside the Empty component with inline-SVG architectural drafting drawings, strictly adhering to the Architectural Drafting Standard design system:

1. Streams Blueprint Illustration (StreamsDraftingIllustration):
   • Precise hairline bounding box with corner crosshairs (+) at coordinates (12, 8), (116, 8), (12, 60), (116, 60).
   • Continuous token flow metering pipeline with pulse vector waveform (#0969DA), terminal metering nodes, and dimensional tick marks.
2. Cascades Blueprint Illustration (CascadesDraftingIllustration):
   • Hierarchical tree layout with root project block, orthogonal split routing vectors, junction dots, downstream tier-1/tier-2 dependency nodes, and ratio directional ticks.
3. Receipts Blueprint Illustration (ReceiptsDraftingIllustration):
   • Cryptographic audit voucher ticket with hairline digest barcode vectors, canonical hash ledger guide rows, and concentric verification seal target with crosshair axes.
4. Zero External Assets:
   • All illustrations are lightweight, responsive, pure inline SVGs utilizing theme CSS variables (var(--color-paper) and Tailwind classes text-lead, text-ink).
5. Auto-detection & Flexibility:
   • Automatically maps existing page icons (water_drop, account_tree, receipt_long, account_balance_wallet) to the appropriate drafting blueprint, while accepting an explicit variant?: "streams" | "cascades" | "receipts" | "default" prop.
6. Verification:
   • Passed tsc -b and vitest run (30/30 tests passed).
