# v3/Caddyfile
#
# Caddy reverse proxy for LibNovel v3.
#
# Environment variables consumed (set in docker-compose.yml):
#   DOMAIN              — public hostname, e.g. libnovel.example.com
#                         Use "localhost" for local dev (no TLS cert attempted).
#   CADDY_ACME_EMAIL    — Let's Encrypt notification email (empty = no email)
#
# Routing rules:
#   /health                        → backend:8080  (liveness probe)
#   /scrape*                       → backend:8080  (scrape task creation)
#   /api/browse                    → backend:8080  (MinIO-cached browse pages)
#   /api/book-preview/*            → backend:8080  (live scrape, no store write)
#   /api/chapter-text-preview/*/*  → backend:8080  (live chapter, no store write)
#   /api/chapter-text/*/*          → backend:8080  (chapter markdown from MinIO)
#   /api/reindex/*                 → backend:8080  (rebuild chapter index)
#   /api/cover/*                   → backend:8080  (proxy cover image)
#   /api/audio-proxy/*/*           → backend:8080  (proxy generated audio)
#   /api/scrape/*                  → backend:8080  (scrape job status/tasks)
#   /*  (everything else)          → ui:3000       (SvelteKit — handles all
#                                                   remaining /api/* routes too)
#
# The SvelteKit UI itself proxies to the backend for: ranking, voices, search,
# browse-page, presign, audio, progress, and the Go /api/progress endpoint.
# MinIO and PocketBase are NOT exposed publicly.
