dev: serve at dev.thermograph.org behind basic auth, bound to loopback
Dev was mesh-only: bound to 10.10.0.2, no DNS record, no Caddy site. A public
record now exists for it, so it gets a real front door instead of a name that
resolves to a timeout.

Three things keep that acceptable on a box that also runs Forgejo and its CI
runner, and all three are load-bearing together:

  - the stack binds LOOPBACK, so the site block is the only route in — not even
    the mesh reaches the app directly, which is what makes the guard total
    rather than decorative,
  - HTTP basic auth, so a stumbled-upon URL is not a running build,
  - X-Robots-Tag: noindex, so dev never competes with thermograph.org for the
    same content in a search index.

The credential in Caddyfile.vps1 is a bcrypt hash, not a password.

# Dev overlay for the LAN dev server (deploy/deploy-dev.sh):
#
# docker compose -f docker-compose.yml -f docker-compose.dev.yml up -d
#
# Split-repo adaptation: the monorepo's docker-compose.dev.yml (see
# thermograph/docker-compose.dev.yml) overlaid a base file where backend and
# frontend had `build: .` -- dev's whole point there was `--build` in place from
# the working checkout. This infra repo holds no Dockerfile at all (each service's
# lives in its own app repo, thermograph-backend / thermograph-frontend), so the
# base docker-compose.yml already has NO `build:` for either service, only
# `image: .../${BACKEND_IMAGE_PATH}:${BACKEND_IMAGE_TAG}` (and the frontend
# equivalent) -- same registry-pull model as prod/beta, just pointed at a dev tag
# by deploy-dev.sh. This overlay must NOT reintroduce `build:`; it only relaxes
# resource caps and LAN-exposes a port, same as the monorepo overlay did.
#
# Differences from the prod stack:
# 1. backend is published on ${DEV_BIND_ADDR}, defaulting to LOOPBACK.
#
# This used to be a flat 0.0.0.0:8137, from when dev ran on the operator's
# LAN box and the point was for phones on the Wi-Fi to reach it. Dev now
# runs on vps1, a public VPS, where 0.0.0.0 would publish whatever
# unreviewed branch is in flight to the entire internet — with no Caddy, no
# TLS and no auth in front of it.
#
# So the default is 127.0.0.1 — safe anywhere, including a laptop running
# `make dev-up` — and on vps1 deploy/env-topology.sh keeps it there. Caddy
# fronts the stack at dev.thermograph.org with TLS, HTTP basic auth and
# X-Robots-Tag: noindex (deploy/Caddyfile.vps1). Loopback is what makes that
# guard total: the site block is the only route in, so nothing reaches the
# app without the password — not even from the WireGuard mesh.
# 2. frontend's port publish is dropped entirely -- dev has no Caddy to reach it
# directly, so it stays compose-internal-only, reached solely through
# backend's own reverse-proxy fallback (THERMOGRAPH_FRONTEND_BASE_INTERNAL,
# see backend/web/app.py's _proxy_to_frontend in the backend repo). This
# keeps the dev stack serving the one URL it always has, at :8137.
# 3. The CPU caps are removed -- dev runs UNCAPPED (no thread/CPU limits), unlike
# prod's backend=4 / frontend=2 / db=2 allocation. `!reset` drops the base
# value (both the top-level `cpus:` and the Swarm-style `deploy.resources`
# block the base file carries for parity).
# 4. backend/daemon/lake get a second env_file entry pointing at an OPTIONAL
# copy of the render under $APP_DIR (`required: false`, so it is a no-op
# when absent). It exists for snap-packaged Docker, which is confined to
# $HOME and cannot see /etc/thermograph.env at all — not a permissions
# error; the file simply does not exist as far as snap-confined Docker is
# concerned, so the base file's env_file entry silently loads nothing.
# deploy-dev.sh now produces the mirror ONLY when it detects snap Docker,
# which vps1 (ordinary apt Docker) is not — there, dev reads
# /etc/thermograph.env like beta and prod do, and no plaintext copy of the
# render is written into the checkout. compose appends env_file lists across
# overlays (last-wins on duplicate keys), so this stays additive.
