"""
api_server.py — Optional Flask bridge so the browser dashboard (or the React
entry app) can push entries to Tally with one button.

The dashboard at azizsaif.com/Murtuzabhai-tally is 100% client-side and never
needs this. Run this ONLY if you want the browser to talk to your local Tally.

Run:  python api_server.py    (listens on http://localhost:5000)
