Detailed Description

A GUI-side view onto one pipe's currently published backbuffer: wraps the pipe cache's own memory, never an independent copy (pixelpipe_hb.c owns the keepalive ref). Callers declare and own their own instance(s) - darkroom keeps one for dev->pipe and one for dev->preview_pipe, Studio Capture owns exactly one, for its main pipe only. Initialize .hash to DT_PIXELPIPE_CACHE_HASH_INVALID before first use - a zero-initialized (calloc'd) instance looks like a valid hash of 0, not the sentinel.
