/* Adjust capture limits here. These are backend policy, not protocol limits.
 * modes.m uses these bounds to advertise native camera resolutions; nv12.c uses
 * the same ceilings when packing samples. No additional resolutions are synthesized.
 *
 * The limits bound capture cost and uncompressed NV12 traffic. They also apply
 * when the shared codec selects H.264 output. Revisit them when adding VideoToolbox
 * encoding, but retain suitable limits for NV12 passthrough; encoder availability
 * alone does not mean that compression was negotiated for a stream.
 *
 * NV12's even dimensions and plane layout, AVFoundation's available output formats,
 * and exact lookup of previously advertised modes remain required runtime checks.
 * The shared descriptor count limit is ECAM_MAX_MEDIA_TYPE_DESCRIPTORS in ../camera.h.
