Pilot tool that sends a receipt photo to Claude, classifies the budget
category, and for groceries locates + categorizes each line item, rendering
an annotated PNG with per-category subtotals. Uses the Claude cloud API
(claude-opus-4-8) for pixel-accurate bounding boxes; reads CLAUDE_API_KEY
from ../.env.
Complementary to the local-only OCR/ tools (ollama, no cloud).
