nx_nishios_events.nx -- NishiOS GUI rung-3: an INPUT EVENT LOOP (interactivity). A desktop you can't touch isn't an OS GUI. This adds the real loop: data-driven windows (a window table), a click handler that RAISES the window under the cursor (focus -> z-order changes from the event), and cursor tracking. It renders frame 0 (win "files" on top), processes a CLICK on the lower "terminal" window, then renders frame 1 -- where that window is now raised to the front. The z-order change between the two frames IS the proof the event loop works. The event SOURCE is scripted here (the emu has no live PS/2 mouse; that driver is the wiring rung), but the event-handling LOGIC -- hit-testing, focus-raise, cursor move, re-render -- is real. KAT: frame0 overlap shows the top window; after the click, frame1 overlap shows the RAISED window; the cursor moved to the click point; both frames exported as real BMPs. HONEST SCOPE: scripted events + 2 windows. Live PS/2 input, drag, a full ASCII font, and wiring into the boot kernel's framebuffer are the next rungs.
