Rohlik Score од pali

Rohlik Score overlays a colored Nutri-Score badge (A_E) on every product card while you browse rohlik.cz.

How it works:
- Fetches exact nutrition data from rohlik.cz's own product API
- Falls back to Open Food Facts international database
- Computes Nutri-Score from raw macros when no database match is found

Features:
- Color-coded badges: dark green (A) _ red (E)
- Hover badge to see full breakdown: energy, fat, sugar, protein, salt, fibre
- Toggle ratings on/off via the panel (click extension icon)
- All data cached locally for 24 hours _ no tracking, no accounts
- Estimated scores marked with ~ indicator

Data sourced from Open Food Facts (open database, no API key required).
