D3-TUI will use SPECTRE’s profiler for performance monitoring:
/* In main.c */
void main_loop(void) {
d3tui_shachi_prof_frame_begin();
d3tui_shachi_prof_terminal_begin();
d3tui_term_update(terminal);
d3tui_shachi_prof_terminal_end();
d3tui_shachi_prof_render_begin();
d3tui_term_render(terminal);
d3tui_shachi_prof_render_end();
d3tui_shachi_prof_frame_end();
}
