# Knobuss - optional carousel screen (base id 10). A Gyruss-style tube shooter: your ship orbits the rim, you
# auto-fire inward, foes spiral out from the centre. Turn the knob to aim, blast them before they
# reach you. Remove it: drop this file from your config's package "files:" list. Nothing else to edit.
# Scores (g_gy_top / g_gy_best) + the "Reset scores" settings action live here - fully self-contained.
#
# Perf: ship + bullet pool (6) + enemy pool (10) are all positioned each tick from float arrays in
# ONE lambda (lv_obj_set_pos over a pooled lv_obj_t* array - LVGL can't index a widget by a runtime
# var), so per-tick cost is constant and the action chain stays shallow. Sprites have a fixed src
# (enemies alternate enemy/enemy2 by slot), so there are no per-tick image swaps.
