Same-origin (Caddy) means the SPA reaches /api and /nats through its own
origin in production, but those relative paths do not exist on the bare Vite
dev server, so `pnpm dev` no longer connects. busService already reads
VITE_BUS_HTTP / VITE_BUS_WS as overrides of the same-origin defaults — this
documents that path (Option A, no proxy code) and moves the dev server off the
port reserved by an unrelated local app.
- vite.config: dev server port 5173 -> 5174 (5173 is in use by another local
app). strictPort left off so Vite falls back to the next free port. Comment
explains the same-origin/dev split and the env-var override.
- app.md: Ejemplo and the CORS gotcha document the exact dev command
(VITE_BUS_HTTP/WS pointing at a cluster node) on :5174 and the same-origin
production model.
