Instameex - Web Front
------------------------------------
Flask front end for assembling Instagram-compliant HDR JPEGs (gain map
injection adapted from kostis-kounadis/instagram-hdr-assembler — see
LICENSE). Gives you a browser form instead of a terminal, and
surfaces the assembly report (including the "GainMapMin is negative"
warning) on a results page.

This file is just the entry point — see src/script/app/ for the app itself:
  src/script/app/config.py       constants
  src/script/app/jobs.py         in-memory job registry + heartbeat/reaper
  src/script/app/validation.py   upload + Instagram resolution checks
  src/script/app/assembler.py    gain-map assembly pipeline
  src/script/app/routes.py       Flask routes

Run directly:      python3 main.py
Run in Docker:      see Dockerfile (gunicorn main:app)
