The standard vortex entry point:
<shell> serve HOST PORT websocket server (login applies)
<shell> -c EXPR evaluate one block as the local wisp
<shell> SCRIPT evaluate a file as one block
<shell> REPL on a tty, else stream blocks from
stdin (the ssh transport: blocks in,
show-rendered Reply frames out)The evaluator is warm (one persistent GHC session, booted at startup) unless VORTEX_COLD is set, which reverts to a fresh session per block — useful for comparison and for one-shot runs where the boot would not be amortized.
