-- site — writeonce.de: the language tutorial, served BY the language.
-- Full stack in one binary: writeonce-framework ([deps]) for HTTP/routing/
-- auth, wo-html ([deps]) for server-rendered pages with Tailwind-style
-- utilities, @table + WAL for the chapters themselves. The site is its own
-- final chapter: /ch/serving shows this file's shape.
--
--   SITE_TOKEN=... WO_DATA=./data ./site 8080
--
-- Behind nginx/caddy for writeonce.de: the proxy terminates TLS and
-- forwards to 127.0.0.1:8080 (the framework speaks HTTP/1.1 keep-alive).
--
-- This file is the BOOTSTRAP and nothing else: seed, routes, serve. The
-- model is types.wo; every feature is a directory holding its view and
-- its controller.
