Environment / auth

OMA_DB
Path to the SQLite store. Defaults to a fixed per-user data directory; set this to isolate a store.
OMA_VIEWER
Browser viewer on loopback. On by default; set to 0 to turn it off.
OMA_DYNAMIC_TOOLS
Set to 1 to also expose one open_<name> tool per saved app. Off by default, because it costs prompt cache.
