// orcaFrame.c - ORCA-style desktop application.
//
// Opens a Window Manager window via startdesk()'s full toolset chain,
// runs an event loop via TaskMaster until the user clicks the close
// box, presses Q, or the watchdog fires.
//
// Modeled after ORCA-C's Frame.cc / Reversi.cc samples.  Exercises
// our LLVM/Clang toolchain + the new bank-byte relocation
// end-to-end against the real GS/OS 6.0.2 / 6.0.4 Window Manager.
//
// Phase 4.1 migration: NewWindowParm and event dispatch boilerplate
// folded into iigs/uiBuilder.h and iigs/eventLoop.h respectively.
