Meal Scan — Macronutrient Estimator

Upload a meal photo and get an estimated calorie / protein / fat / carb breakdown. A YOLO model segments the plate into meat, rice, and vegetables; optional Gemini Vision refines the food identification and the USDA FoodData Central database supplies nutrition facts.

Configuration (set these in the Space's "Settings → Secrets")

Secret	Purpose
WEIGHTS_REPO_ID	Hugging Face model repo holding best.pt (e.g. your-username/meal-scan-weights)
GEMINI_API_KEY	Optional. Enables Gemini food identification.
FDC_API_KEY	Optional. Enables live USDA nutrition lookup.

If the Gemini or USDA keys are absent, the app falls back to generic food labels and a bundled sample macro table, so it still runs.
