/* Host-safe ports of the recovered gate/mode helpers:
 *   - allocate_layout_gate_mask_bit @ 1000:0d1b
 *   - free_layout_gate_mask_bit     @ 1000:0d5d
 *   - set_mode_or_status_bits       @ 1000:19fb
 *
 * The original routines reserve a five-word gate record in the primary record
 * buffer, run a parser pass, then clear/restores parser/runtime flags.  Overlay
 * jumps are exposed as booleans/counters so the host build remains deterministic.
