# Local web preview for Recl∆Im.

# Builds the release web bundle (~16 s) and serves it on
# http://127.0.0.1:8080 via python3's stdlib http.server so an
# AG-member can poke the demo from a browser without the
# Flutter dev tooling being installed on the reviewer's machine.
#
# Production path (NOT done by this script):
#
#   1. Copy build/web/ to a static host. Hetzner CX-Server +
#      Caddy with auto-HTTPS is the existing F∆I pattern (see
#      fai_chain release-host).
#   2. Set the CSP, HSTS, and frame-ancestors headers Caddy
#      already templates per F∆I deployment.
#   3. Add reclaim.flemming.ai DNS A-record to the F∆I IP.
#
# For local dev: this script is enough.
