10 predefined layouts (single, dual_horizontal, dual_vertical, quad, main_plus_preview, six_grid, nine_grid, sixteen_grid, panoramic, main_with_strip) — normalized [0..1] координаты, port из vf_cuda_grid.c старого FFmpeg patch'а. Применяются к фактическому output разрешению композитора через cfc_composer_set_layout(name). Source pool НЕ пересоздаётся: sources привязаны к индексам cells, layout меняет только геометрию (cell.x/y/w/h). Это даёт zero-disruption switch без потери накопленного state и без re-subscribe к cuframes publishers. ZMQ verbs: set_layout / list_layouts / get_layout. CLI: --layout=NAME перетирает --cell координаты на старте. Используется ONVIF wrapper'ом (gx/cctv-onvif:0.1) для PTZ presets: GotoPreset(token) → ZMQ set_layout(token).
