Stock $D5F2 repaints the cockpit display to the E0 counter readout on
the FIRST increment of $3187/$3184/$3185, so one benign give-up shows
E0000001 forever. New opt-in make_patch.py edit 5 hijacks the render's
LDX #$2038 into a 30-byte cave at $E000: all three counters below N ->
exit via the routine's own epilogue (registers restored, display
untouched); any >= N -> resume the render. Counters still accumulate.
Built + disassembly-verified (not yet burned): RIOv4_2_patched_e0t5.bin
(9600) and RIOv4_2_patched_31250v2_e0t5.bin (FastRIO). Docs updated.
