Caddyfile

# /etc/caddy/Caddyfile on the VPS.
# Each domain's A/AAAA record must already point at this VPS — Caddy provisions a
# Let's Encrypt cert on first request and auto-renews. Nothing else to do for TLS
# (just make sure ports 80 and 443 are open).
#
# Layout:
# thermograph.org/* -> the Thermograph app (path-split across
# backend/frontend -- see below)
# emigriffith.dev/ -> static portfolio site (served straight from disk)
# emigriffith.dev/thermograph* -> permanent redirect to thermograph.org (the app moved)
#
# Thermograph now owns thermograph.org's root, so both services run with
# THERMOGRAPH_BASE=/ (see /etc/thermograph.env) — pages, assets and API all sit
# at "/" with no sub-path prefix. Repo-split Stage 4: backend and frontend are
# two containers now (docker-compose.yml), each on its own loopback port --
# Caddy path-splits directly to whichever owns a given path, so the browser
# still sees one apparent origin. Repo-split Stage 7a flipped which side owns
# the enumerated list: frontend now owns everything (content pages, the
# interactive tool's SPA shells, every static asset, the dynamic IndexNow key
# file) except the short, stable set below, which mirrors backend/web/app.py's
# own routing exactly (a single catch-all proxy to frontend for everything
# else) -- unlike frontend's paths, backend's don't grow every time a new
# static asset filename is added. A gap in this list still just degrades to
# "one extra hop" through backend's own proxy fallback, never a 404.
